Salutations Stats & Strategy Specialists
(Today’s post is sponsored by the letter ‘S’)
A couple years ago, I wrote a post about KEM farming (which can be found here) and how it yields donuts. Since that time, many of you like myself have gone on to grow your KEM farms to over 100 KEMs, earning over 100 donuts every 4 hours, as you have raised your XP bonus percentage into the thousands.
At this point, some of you may wonder is it worth always going for 3 donuts when you fill an XP bar? Or are you better spending that money on additional KEMs?
Let’s take a look and see…
ALWAYS GOING FOR 3 DONUTS
There are 5 possible outcomes of those donut boxes if you always go for three donuts:
- 3 donuts on first try
- 2 donuts on first try, 3 donuts on second try (Cost $50,000)
- 1 donut on first try, 3 donuts on second try (Cost $50,000)
- 2 donuts on first try, 1 donut on second try, 3 donuts on third try (Cost $100,000)
- 1 donut on first try, 2 donuts on second try, 3 donuts on third try (Cost $100,000)
If we average these 5 probable outcomes (taking into account the first possibility is twice as likely as the other 4), you’ll earn 3 donuts at a cost of $50,000.
18 donuts at a cost of $300,000 / 6 = 3 donuts at a cost of $50,000
So “Always Going For 3 Donuts” cost $16,667 per donut.
$50,000 / 3 donuts = $16,667 per donut
THE QUESTION?
Now the question is are you better off spending that money on more KEM instead of going for 3 donuts? Another way to put it, can you earn a donut for under $16,667 by buying extra KEMs?
SPENDING MONEY ON KEM
Unlike the 5 outcomes that exist if you always go for 3 donuts, there are only 3 possible outcomes of those donut boxes if you stop at the first choice:
- 3 donuts on first try
- 2 donuts on first try
- 1 donut on first try
So the average of these 3 outcomes is 2 donuts when you fill a 1,000,000 XP bar. So 1 donut would require 500,000 XP.
6 donuts / 3 = 2 donuts
1,000,000 XP / 2 donuts = 500,000 XP per donut
With $16,667, you can buy 1.157 KEM at a cost of $14,400. [For the sake of simplifying the math, I’m ignoring the fact that the first 24 KEM are cheaper, resulting in a slightly lower average KEM price than $14,400 depending on the size of your farm. However, the more KEM in your farm, the closer the average cost gets to $14,400.]
$16,667 / $14,400 per KEM = 1.1574305555555555555555555KEM
So the question is how can we earn 500,000 XP with 1.157 KEM. Or alternatively, that comes down to 431,991 XP per KEM.
500,000 XP / 1.157 KEM = 431,991 XP per KEM
To earn 431,991 XP per KEM with the XP collider on, we divide by 5 for the XP collider resulting in 86,398 XP per KEM.
431,991 XP per KEM / 5 = 86,398 XP per KEM
When we divide this by 2,000 (the base XP of KEM), we get 4,320 as the XP multiplication factor.
86,398 XP per KEM / 2,000 XP per KEM = 4,320%
Minus the 100 that just naturally exists gives us a required 4,220% XP bonus in order to earn 431,991 XP per KEM with your XP collider on.
CONCLUSION
That means you need an XP bonus of 4,220% to make it wiser to spend your money on more KEM and just stopping at the first box, rather than keep going until you get to the box with 3 donuts.
4,220% is the magic XP number.
What is your XP bonus? Is it over 4,220%? If it is over 4,220%, have you been stopping at your first choice? If it under 4,220% have you kept going until you get 3 donuts? Sound off in the comments below. You know we love hearing from you.
At some (percentage) point, you will probably (hopefully) decide that KEM farming is just a waste of time. I’m not sure where that % is for you, but i’m at 2,609% (without xp collider) and i know i passed it at least 1,000% ago. At 2,609% there is no need to grind KEMs every 4 hours or purchase RTTs or Blood Mobiles and more. I have over 20,000 donuts and can purchase every item /character i want in every event. In the last 6 months most of the mystery boxes have been almost empty because i’ve got all the characters and almost all the buildings. I’m hardly sending anyone on tasks anymore unless it’s required and i don’t by rule enable the XP collider until i need to restock my donut supply which is seldom. I find Maggie when i feel like it, and I certainly don’t complete monorail tasks (but i do have Little Lisa’s recycling plant that does generate blue prints automatically) If i turn on the collider just for a day and send everyone on 24 hour jobs (which is the worst choice if you really need to collect xp) i can easily collect 60+ donuts. i can bang out blood mobiles at a rate of more than 1 million xp / truck. Somewhere between 1K-2K% you will hopefully find like i have that the grind just isn’t worth it, with very little effort you can afford almost everything your heart desires (in TSTO). There are better things to do than to be tied down to this game.
If you are trying to get your bonus % to somewhere in this level (where the grind is no longer worth it) then focus on
a: placing every SH building for their hidden XP bonus
b: look for items in the vault that offer a donut rebate. some of these are a good deal and some aren’t. Anything that gives you a bonus to donut ratio of < 20 donuts / % is a generally a good deal.
c: Purchase Mystery boxes, yeah lots of the prizes really suck (even the ones w/ bonus %) but it seems to be pretty common knowledge that you can increase your bonus % at a rate of 1% for 9 donuts, which is a good ratio.
d: occasionally EA will offer new or repeat items in the store that have a good donut / bonus ratio. (less than 20 to 1). Some things that come to mind are the international flag set that has been offered more than once, and the Bart parade balloons which were just recently offered.
If you are struggling to increase your %, these things above are what you should focus on. Don't worry about missing some limited time offer (they all come back and usually at a cheaper price).
Good Luck and happy tapping.

I started to read the post with great interest and although I’m quite good at maths etc I did start to speed read… Your conclusion agreed with my rough estimation… I was very confident with a bonus of under 2k I was better going for the 3 donut option every time. And the turnaround % I thought would be around 5k for the opposite strategy. My biggest problem is being bothered to do the farming. As long as I have 6k donuts I do it a couple of times a day. When my count goes below 6k I do it every 4 or 5 hours then slack off again.
Sorry for the long post but math is so much fun.
I wondered the same thing a while ago and created a calculator for it. I agree with raoplex’s comment that your 5 outcomes are not equal. You have a 1/3 chance of getting 3 donuts with 0 additional guesses, 1/3 chance of getting 3 donuts with 1 additional guess, and 1/3 chance of getting 3 donuts with 2 additional guesses. Also did you factor in the selling of the KEM farm in to your equation?
When I started my calculator, I determined that question of “Should I guess again?”, is always answered “It depends”.
What you proved is the most efficient way of converting In Game Currency to donuts. Someone may have a small farm, but still saving some IGC to buy more land. Or a high percentage player may find it quicker to always go for 3 instead of farm more.
One other thing that I explored is whether you should stop at 1 or 2 donuts. If you get 2 donuts on your first guess, you are looking for the 3 donut box (or 1 additional donut). You have .5 probability to find it in 1 guess, and a .5 probability to find it in 2 guesses (so your average is 1.5 guesses/1 donut or $75,000/1 donut).
Another example is if you have opened 2 boxes and still did not get the three donuts. Your next guess would be 1 guess for 1 donut, or $50,000/1 donut.
For my calculator I determined there are 5 variables that determine if it is more efficient to guess again.
1. Is your XP collider on?
2. What is your bonus percentage?
3. How many KEM’s do you have in your town
4. Cost of the additional box guess (level up box costs $50,000, but Find Maggie is $150,000)
5. How many donuts did you get on your first guess.
If your XP collider is on, a KEM farm larger than 25, and $50,000 cost for an additional guess, here are my calcluations:
-If your bonus percentage is less than 620% you should always guess until you get 3 donuts.
-If you bonus percentage is between 620% and 980%, and get 2 donuts on your first box, keep it. If you get 1 donut on your first box, guess until you get 3.
-If your bonus percentage is between 980% and 1520%, end whenever you get 2 donuts.
-Above 1520% you are more efficient always taking the first box, and KEM farming more.
I can send you my calculator if you would like.
What about the strategy of stopping after getting at least 2 donuts?
1. 3 donuts on the first try ($0) (1/3)
2. 2 donuts on the first try ($0) (1/3)
3. 3 donuts on the second try ($50,000) (1/6)
4. 2 donuts on the second try ($50,000) (1/6)
That gives you an expected values of about $16,667 cost and 2.5 donuts, or $6,667 per donut. Compared to always going for 3 donuts, you save $10k at a cost of 0.5 donuts.
I haven’t checked, but it may be worth using this strategy when XP grows beyond a certain point.
I did comment below on this for someone (I believe the verr first comment). But the only thing I changed was option 4. If you got 1 donut on the first try and 2 donuts on the second try, why would you stop? You know that the 3rd box is guaranteed to give you 3 donuts. If you do that, your magic number is actually a whopping 7,580%.
If you stop after 2 attempts, you don’t spend $50k to get that third donut which buys you about 3.5 KEMs.
The really bad case is 2 donuts on the first attempt because you could spend $100k to get that third donut which would otherwise buy you almost 7 KEMs. This will happen 1/2 of the time when you get 2 donuts on the first attempt.
Is it worth it in the long run? I haven’t checked, but like I said, it saves $10k at a cost of 0.5 donuts against the “always 3” strategy.
Maybe the best strategy is “always 3” when you get 1 donut on the first attempt, but stop if you get 2 donuts on the first attempt. Then you will never spend more than $50k per extra donut. This is the strategy I use with “Where’s Maggie” and I should probably use it with KEM farming, too.
It’s a good strategy and one I advocated on this site a few years ago when I was in-game cash strapped. I called it the Blackjack strategy.
You get a 3, winner winner chicken dinner.
You get a 2, stand.
You get a 1, hit me.

Is there an App Store update expected to be dropping today or is that expected to be tomorrow?
🤷♀️ your guess is as good as ours
Does anybody know what the limits are for in-game cash and donut stockpiles?
I’ve got nearly 2 billion in-game dollars and nearly 9000 donuts stashed away in my main game, and I’d hate the counters to click over to zero and have to start again 🙂
Thanks for the interesting sums, Safi!
At somewhere around 4.3 billion, your in-game cash starts reversing. So if you have 5 billion in-game cash, your display would show 3.6 billion, though in a different font colour.
A couple days ago, I finally reached the maximum amount of game cash: 4,294,967,295. The number changes to red and what follows is a humourous exchange between Frink and Homer. Spending cash will then lower the amount, otherwise it’ll just stay the same.
Oh cool, it doesn’t go down in red anymore? Just stays at 4.3 billion?
(Spoiler alert, I actually have a post coming out on that number next month or the last week of January)
Yes, once you spend some $$$, it changes back to white; it turns red when you reach the limit again, though Frink and Homer’s exchange only occurs the first time. I KEM farm a little, though I stop if I get 2 donuts on the first try; the reasons being is that I’m willing to pay $50000 for a single donut but not $100000 and that it takes 2-3 seconds after the first try before being able to make another try.
Thanks for the replies – it’s aways good to see a fellow Python fan around!
I know it does not affect the result much, but when you average the cost for getting 3 donuts in the five possibilities the free possibility (3 bonuts on the first try) should be weighted twice as much because it occurs with probability 1/3, whereas all others occur with probability (1/3)(1/2)=1/6. (Because we open two or more) As always, thanks for the in-depth posts!
Excellent post… Dude I am relative new to KEM but I have the in-game cash to build over 300 kem.. and go for the 3 donuts every time, but I kind of KEM farm every other day.. that keeps a balance on income and expenditures. so I get 320 donuts the day I KEM. 🙂 the key point is Balance. 🙂
Who else does this not matter too, level 558 with 201%. I have no way to increase it so I’mkinda stuck. But for finding Maggie I always go for three.(the left one has a 90% chance at a three for me!)
The best way to increase your percentage (next to getting all 5 Springfield Heights beach hideaways and accessories) is by purchasing Mystery Boxes for 6 donuts. Typically for every 100 donuts you spend on Mystery Boxes, you’ll get enough Itchy & Scratchy Billboards and Channel 6 News Vans to raise your XP bonus 8-10%.
So what I would do in your case if you were looking to increase your XP bonus and get to the point where you are, as the title says, an “Advanced” KEM farmer:
First, cut down the number of KEMs you are farming if you are running out of in-game cash.
When you cut it down, you may find you’re only earning fewer donuts/4hr for now.
After a few days or a week, you’ll have earned 100 donuts.
Now spend those 100 donuts on Mystery Boxes raising your XP bonus 8-10%.
Now when you farm, you’ll earn more XP per KEM and start earning more donuts/4h without losing in-game cash.
Eventually, as you keep repeating this sequence, going up 8-10% every few days, you start decreasing the number of days it takes to get to 100 donuts.
Pretty soon, you’ll be earning 100 donuts/4h.
Your math is off here. There are really only 3 possible outcomes that are equally likely when one goes for 3 donuts every time:
1. 3 donuts on the first try ($0)
2. 3 donuts on the second try ($50,000)
3. 3 donuts on the third try ($100,000)
So that’s an expected value of $150k per 9 donuts, or about $16,667 per donut, not $20k per donut.
Fixed
Been at 1230% for a while, doing 109 KEM’s every 4 hours and getting enough donuts for all the premium items at events. Still wanted to increase my % but my girlfriend said she wants to catch up to me so i’m “forbidden” hahahaha.
Totally confused- never could follow what to do with all the math jibberish to follow-and to be honest could never read an entire article about it because of it. I honestly quit reading the articles.
Great post Safi! I’m at just over 1100%, KEM farm as needed, and have lots of jet bikes hidden behind buildings.
~MIB👤
Jet bikes are the way!
I keep reading these posts when they come up, but I still can’t figure it out. 😛
The best way to raise xp is getting all Springfield heights bonuses. I only rtt farm
Baffled with maths, and its only the 3rd of January, i kem, i dont always get 3 donuts, i keep going till i get the 3, i have over 100 million game cash, works for me, pass the eggnog.
4000% bonus , 4 logs per day : 500 donuts + 18M $.
I have a 725% XP bonus. I farm 48 KEMs every four hours. I get around 100 donuts a day (including the monorail and finding Maggie) and I always go for 3. My In-game cash always accumulates. I try to keep at least $20mill on hand but since I have no more land to buy and I get all the trees and shrubs from Treestache and various other designing items from digging and kicking turtles, I really only spend on KEMs.
Hey is it worth start farming when my XP bonus is just 187%??
Yes.
I only have 220% and in that way i get 2 donuts every 4 hours
I’m at 2534%, and I always go for 3 donuts, mostly because in-game cash is so cheap and I can’t stand to leave donuts on the table. (In-game or in real life, I’m afraid. 😉 )
But I’m a very casual KEM farmer. I only have a size 24 farm, only make 18 donuts from it, and only farm when I want to buy something. I keep the XP booster charging 24/7, and just doing daily challenges, events, and picking up building income in passing pays for the charger and almost all the donuts I need.
I think you’re at a point where just buying RTTs is easier and faster.
I used to obsess over this, and actually did the same math for myself two years ago. Now I occasionally farm by buying blood mobiles, usually around 100 or so in one go. In less than ten minutes I’ll earn about 200 donuts at a cost of approx. $55,000 per donut. I compared it to Kem farming with the same amount of money and it feels like it took me way more time and tapping to get the same. I never redid the actual math but I prefer spending ten minutes every once in a while over constantly “working”. And I get enough cash from regular gameplay to keep doing it, buy all the premium items and never go too far below 2000 donuts in the bank…
Yes, exactly. KEM farming is way too grindy. I have a bonus of 690% and I Rat Trap Truck farm with the multiplier on for 10 days, then float along for a couple weeks building up $$ to ~$40M, then repeat. I can generate enough donuts to pretty much buy anything I want, and the only extra effort is buying/selling RTT every so often (5 minutes, tops) during the multiplier days.
Me too…since game cash is essentially useless, and it just keeps piling up, it doesn’t matter to me if I spend it efficiently. I occsionally farm RTTs for a bit, collect a few hundred donuts, then pile up more cash till I need more donuts. At this point, it’s impossible to deplete my cash…it always builds up faster than I can use farming RTTs.
I’m currently running my game everyday at a steady 850% bonus (have another 800% in group storage which I pull out temporarily when I farm) and run the collider 24/7, so I pull in between 9-12 donuts a day just playing the game (I have 280 characters on 24 hr jobs) which pays for the collider and any small purchases I make.
I agree that a high bonus % is important, but having a high number of earning characters is equally important.
My advice for advancement is to buy Mystery boxes to increase your bonus, but also focus on buying more characters…they will bring in lots more cash and xp on a daily basis than any property you can add to your town.
For cash and XP, you are generally better off using your donuts to increase your bonus versus buying characters/buildings. The best price you get for a character is usual around 60 donuts. That would get you 10 mystery boxes, which on average would increase your bonus by 6%+. If you already had 17 characters and 17 buildings that would be equivalent of adding another character and another building.
Of course, for pleasure sake and quests, buying characters and buildings is better.
Hi Charles…true enough, if you’re still focusing only on increasing your bonus. I agree that to increase your bonus, mystery boxes are the best investment, but to utilize that bonus you need income coming in. Our choices for income are characters and property, and my advice is to focus on characters to get a better return on your investment. If you have a high multiplier with a minimal income coming in, you have very little to multiply and your bonus % is wasted. I believe that you need to have a balance in aquisitions to make that high bonus worth anything. Characters bring in more cash and xp, there’s no land needed to place them, and they don’t boost your piece count with a bunch of decorations.
I think that for every 50% you boost your bonus, you should add a character to increase your income as well. Just my opinion.
If you buy Mystery Boxes (6 donuts) you will get Lard Lads which produce income. So for 100 donuts you will get 11% bonus plus 2 Lard Lads and some items you can sell for cash. I think when you are starting out the sweet spot is around 17 of each of the houses and gulps and K Burgers. You will get enough characters through the quests.
I think your math might possibly be a little off… You’re factoring in the second try options to come up with five possible outcomes, but you’re never actually stopping on the second try in your analysis; it’s either the first try or the third. As such, the average price per donut should probably be 50,000, rather than 60,000. Mind you, this probably doesn’t change the final answer… But it does change the intermediary numbers.
No, in options 2 and options 3, I do stop at the second try.
Also, those five options don’t have equal probability. Having 3 donuts in position 1, 2 or 3 have equal probabilities. If you want to consider all permutations as equal probability you have to factor in cases where you get 3 donuts in position 1 with 2 donuts followed by 1 donut AND 3 donuts in position 1 and 1 donut in position 2 followed by 2 donuts. Again, conclusion isn’t much different.
While there are more possibilities or where the 1, 2, and 3 donuts may be hiding, there are only 5 possibilities of getting to the 3 donuts regardless of where they are hiding.
You have a 1/3 chance of getting 3 donuts on the first try.
You have a 1/3 chance of getting 2 donuts on the first try followed by a 1/2 chance of 3 donuts on the second try, or 1/2 chance of 1 donut on the second try and 3 donuts on the third try.
You have a 1/3 chance of getting 1 donut on the first try followed by a 1/2 chance of 3 donuts on the second try, or 1/2 chance of 2 donuts on the second try and 3 donuts on the third try.
Thanks for the post Safi ❤ I was a KEM farmer, now I use RTT because of the time factor. But I always pick once, since I sense that the money is always better spent in more farming.
As shown in my reply to Rui N below, the magic number for rat trap trucks and bloodmobiles is actually 5,900%.
So if you’re XP bonus percentage is below 5,900%, you’re better off spending the money of going for 3 donuts. But if your XP bonus percentage is 5,900% or higher, stop at the first box and spend the money on more rat trap trucks or bloodmobiles.
Here’s the simplest math question: if EA offered it, would you be willing to buy donuts in packs of 3 for $100,000. I know I would, so I push forward with no regrets. I’m at 768%. I lay down 108 KEMs each time I farm.
I also noticed a pattern that works ~60% of the time. I choose the far right box. If it’s 2 donuts, I choose the middle. If it’s one donut, I choose the far left.
As you’re guaranteed at least 1 donut for free, isn’t the cost $30k for the additional 2 that you’re gambling for? That would make the additional donuts more expensive and my back of an envelope calculation would be that the bonus % would still need to be around 2,400% adjusting your figures for my assumption. Still massive and, if you have that level of bonus, pretty irrelevant as you can afford anything and everything anyway!
Interesting stuff though …. thanks for the info Safi
If you do factor in that you’re guaranteed at least one donut on each attempt, than you’d have to subtract 5 donuts for the 5 possibilities, resulting in a net 10 donuts for $300,000, which comes out to the $30,000 per donut you’re referring to.
But then you also have to account for that on the other side of the equation, when you stop at the first box, and subtract 3 donuts for 3 possibilities.
So instead of comparing $60,000 to 6 donuts, you’d be comparing $30,000 to 3 donuts. Granted, I’m still in bed having just woken up, so perhaps not the best time to do advanced math. But I believe you should still come up with 4,220%.
I wonder how you guys get to such a high bonus %? I’m way over level 939, have plenty of items with extra bonuses, numerous Springfield Heights buildings (though not all of available) and with total bonus 263% and 42 KEMs I get mere 6 donuts/4h. Providing I don’t want to overstrain by in-game budget for buying 100 KEMs, what shall I do to increase donut rates?
The best way to increase your percentage is by purchasing Mystery Boxes for 6 donuts. Typically for every 100 donuts you spend, you’ll get enough Itchy & Scratchy Billboards and Channel 6 News Vans to raise your XP bonus 8-10%.
So what I would do in your case if you were looking to increase your XP bonus:
You earn 6 donuts/4hr, lets say you do it TID and earn 18 donuts a day.
In 5.5 days, you’ll have earned 100 donuts.
(If you farm QID instead of TID, you’d earn 24 donuts a day and 100 in just over 4 days)
Now spend those 100 donuts on Mystery Boxes raising your XP bonus 8-10%.
Now when you farm, you’ll earn more XP per KEM and possibly start earning 7 donuts/4h.
Eventually, as you keep repeating this sequence, going up 8-10% every few days, you start decreasing the number of days it takes to get to 100 donuts.
Pretty soon, you’ll be earning 100 donuts/4h.
Quick question, you mentioned TID and QID, what do those stand for? I am at 145% and that is mainly because I noticed that my Springfield Heights had buildings that gave a bonus percent.
I am struggling on getting ten donuts a week and only buy a couple KEMs a day since I am using the majority of my in-game cash to purchase some of these huge buildings and finishing tasks like Burn’s Money Mountain and the Redwood Tree.
TID is latin for three times a day and QID for four times a day.
KEM farming is not a sprint, it’s a marathon. So if it takes you one month to get 100 donuts without losing significant in-game cash, well then it takes you one month. But if you spend those 100 donuts on Mystery Boxes to raise your XP bonus percentage 8-10%, next time it may only take you 29 days to get 100 donuts. As you repeat, the interval it takes you to get those 100 donuts will continue to decrease.
Again, it’s not a sprint, so it won’t happen overnight. But it is a marathon. Keep spending the extra 100 donuts on Mystery Boxes and by January of next year, your XP bonus percentage will be significantly higher and the time it takes you to get to 100 donuts will be significantly shorter.
All of us, whether its myself, Charles, Mikael, or anyone else with a percentage in the thousands, we all started where you are.
I don’t see Mystery Boxes available right now. Am I wrong? What are good ways to increase XP percentage when the MBs aren’t around?
Beach hideaways are the best method for increasing XP, followed by Mystery Boxes. Mystery Boxes are always available:
In the Store, click on the arrow on the right of the three icons on the left that represent Characters, Buildings, and Decorations. This will open the Store menu with all the subcategories. Click on the Gold Buddha Homer, representing Premium items. Scroll all the way to the end and you’ll see Mr. Burns and his 6 donut Mystery Box.
There is an item associated with Springfield Heights that gives like 40% fully upgraded & you can buy 5….they are the thatched hut looking one. I can go look up the proper name,,,but they bump up the percentage pretty good.
Beach Hideaways
Lol… Found the name but when I went to add to my comment,,it hadn’t been moderated yet. So thank you for adding it! They (Beach Hideaways) are definitely worth adding to bump up game percentages.
What is the multiplier threshold for the people that use rat trap trucks? I’m guessing much lower than 3,500%?
A rat trap truck or bloodmobile earn 0.1 XP per in-game cash at baseline, compared to 0.138 XP per in-game cash for a full price $14,400 KEM at baseline. The first KEM you farm for $220 actually earns you a whopping 9.09 XP per in-game cash at baseline.
So KEMs give you significantly more XP per in-game cash than the less efficient rat trap trucks or bloodmobiles. So definitely will be higher than 3,500% with rat trap trucks and bloodmobiles.
Going back to your question, the first part of the equation is the same. If you always go for 3 donuts, you’ll spend $16,667 per donut.
How many rat traps or blood mobiles can you get for $16,667? 0.12626262626 rat trap trucks and 0.11111111111 bloodmobiles.
In order to earn 500,000 XP to get a donut, your bonus percentage for either would have to be 5,900% in order to make it better to spend money on more rat trap trucks or bloodmobiles compared to going for 3 donuts.
So while the magic number for KEMs is 4,220%; it is 5,900% for rat trap trucks and blood mobiles.
I have around 2308%. The in-game currency is high enough to stop worrying about strategies (no offense, Safi 😘) and “repick” only if you feel like doing it.
This is just WAY too much math for me…I recently started this farming thing and I’m probably not doing it the right way but whatever, I’m earning more than before. I’m mostly a freemium player who was on level 300 last month and started farming…took me all month to reach 939. Bad thing is I used most of my cash on KEM’s to level up faster and now don’t have much cash laying around to earn but about 6-9 donuts every 4 hours. Again, too much math for me to try to figure out so, while I’m not getting 100 donuts a day, its more than what I had…comments welcome on how I can improve…just with less math 🙂 Thanks!!!
I kept buying the mystery boxes to boost my bonus % with Itchy and Scratchy signs and Channel 6 News Vans rather than buying other stuff. That accelerated things pretty well.
LOL, too much math. That’s the reason I started the post with the word “Advanced”.
Like AJsouthworth63 said, the best way to increase your percentage is by purchasing Mystery Boxes for 6 donuts. Typically for every 100 donuts you spend, you’ll get enough Itchy & Scratchy Billboards and Channel 6 News Vans to raise your XP bonus 8-10%.
So what I would do in your case if you were looking to increase your XP bonus:
First, cut down the number of KEMs you are farming if you are running out of in-game cash.
When you cut it down, you may find you’re only earning 3-6 donuts/4hr.
After a few days or a week, you’ll have earned 100 donuts.
Now spend those 100 donuts on Mystery Boxes raising your XP bonus 8-10%.
Now when you farm, you’ll earn more XP per KEM and possibly start earning 6-9 donuts/4h without losing in-game cash.
Eventually, as you keep repeating this sequence, going up 8-10% every few days, you start decreasing the number of days it takes to get to 100 donuts.
Pretty soon, you’ll be earning 100 donuts/4h.
What about tried once( getting 2 donughts) will turn out?
I am comparing going until you get 3 donuts compared to stopping at your first choice.
So it is better to stop at tried once (like getting 2 donuts on your first try) if your XP bonus is 4,220% or higher.
I’m not sure if that is what you were asking.
Thank you for the very helpful post! I’m going to start buying those mystery boxes to get my XP bonus up.
I think what Buster03 is asking is what if your modus operandi was to always stop at either 2 or 3 donuts. So, if your first try is 2 or 3 donuts, you stop. But if your first try is 1 donut, then you would always stop on the second try, because it will always be either 2 or 3 donuts.
If your first try is 1, then I see no reason to stop at 2 on your next try, as 3 is guaranteed. However, I could see you stopping at 2 on your first try. If that is the case, you have the following possibilities:
1) You get 3 donuts on first try
2) You get 2 donuts on first try
3) You get 1 donut on first try and 3 donuts on second try for $50,000
4) You get 1 donut on first try and 2 donuts on second try and 3 donuts on third try for $100,000
So you get 11 donuts for $150,000; but with the first two possibilities twice as likely as the latter two, it comes out to $9,375 per donut. Your required XP bonus percentage would be 7,580%.
