From the Mouths of Addicts: Kwik-e-Mart Farming for Free Donuts!

Note from Alissa: So one of the popular requested items on my “what would you like to see on this site during the downtime” post was more details about Donut/XP Farming.  What it is, how it’s done…and what the heck Kwik-E-Mart Farming is.  And of course everyone’s favorite site contributor…Safi…stepped up and offered to write up the post!
Safi reached out to me and we discussed writing up the post.  And in true Safi fashion he stepped in with loads of details, charts, tables and figures!  Full disclosure, this post may be a little daunting for newer tappers or casual Tappers.  There are some great tips in here for those looking to earn free donuts.  Just remember to take your time figuring it all out and go at your own pace 🙂
And now here’s Safi….

“Hi Everybody!” (Hi Dr Nick Safi!)

With the recent release of Level 60 and the end of all levels, the games concept of leveling up has shifted slightly. Once you complete Level 60, you’ll be able to continue to level up to Level 61 and beyond. There’s just no questline, character, or building associated with those levels (Homerlayas excluded).

Initially, you can level up from Level 61 to Level 100 each time you fill up an XP bar of 40k XP. You receive 1 donut for each time you level up, for a total of 40 donuts.

You can then continue to level up from Level 100 to Level 939 each time you fill up an XP bar of 500k XP. You receive 1 donut for each time you level up, for a total of 839 more donuts.

Beyond Level 939, your Level does not go any higher. However, each time you fill up an XP bar of 1 million XP, you have the opportunity to choose one of three boxes for a chance at 1, 2, or 3 free donuts.

TSTO Bonus level up

So there is potential for premium and freemium players alike to score thousands of free donuts as a result of leveling up by continuously filling their XP bar.

Let’s take a closer look at the details and strategies that go into XP Farming…

So how do you fill up your XP bar quickly and efficiently?

There are two great ways to earn XP: Bloodmobile/Rat Trap Delivery Truck farming (Quickly) and Kwik-e-Mart farming (Efficiently).

Both methods obviously will work better the higher your XP bonus is, and work best with the XP Collider turned on as you get 5 times more XP when the XP Collider is active.

XP_ColliderA) Quickly

Well when it comes to filling it up quickly, farming Bloodmobiles or Rat Trap Delivery Trucks has been used for a couple years. Wookiee wrote a wonderful post on the subject over two years ago:

This method requires a pretty decent in-game cash fund that you can blow through to purchase and sell as many Bloodmobiles or Rat Trap Trucks in a short period of time.

bloodmobile rattrap

Each Bloodmobile cost $132,000 and earns 13,200 XP baseline (not including your XP multiplier or the 5x for activating your XP Collider). Likewise, each Rat Trap Delivery Truck costs $150,000 and earns 15,000 XP baseline (not including your XP multiplier or the 5x for activating your XP Collider).

The pros of this method include:

  • You only spend 5 donuts to activate your collider for one day
  • You only need to spend a short concentrated amount of time to farm XP (don’t have to be a regular tapper)
  • You don’t need too much land to farm
  • You earn a lot of donuts in one day

The cons of this method include:

  • You need a large amount of in-game cash in order to maximize your donuts
  • You deplete yourself of your in-game cash

B) Efficiently

Many of you may have noticed a lot of comments recently regarding the term “KEM (Kwik-e-Mart) farming”. Most noticeably brought up by Tapebelt and then discussed heavily by the 6 S’s (Sillyboy, Sparkinsac, SwissWavey, Sandrashill, Simp7fan, and myself Safi), MAB the Great, and Josephine Kick@$$ from June 10th to June 15th on another post by Wookiee:

The pros of this method include:

  • You don’t need a large amount of in-game cash in order to use this method
  • Arguably the biggest benefit is that you don’t deplete your in-game cash
  • You earn more XP per in-game cash invested than farming with Bloodmobiles or Rat Trap Delivery Trucks
  • You continue to earn free donuts on a daily basis

The cons of this method include:

  • You need to invest a lot more time as this is a long-term strategy (works best with addict tappers who check in multiple times each day)
  • You continuously spend 25 donuts to keep your collider on for stretches of ten days
  • You need some land to farm your Kwik-e-Marts

Now everyone generally has one Kwik-e-Mart in their Springfield, which brought Apu into their game when purchased for $220 during the tutorial levels. This original KEM can no longer be sold.


Subsequent KEM have dynamic pricing – in that the price increases for each additional KEM you purchase from $220 for the 2nd to $12,400 for the 25th KEM; and than remains constant at $14,400 for every KEM beyond the 25th.


The resale value of KEM is the same as all other items, 25% of the purchase price. So if you spend $100,000 on KEM farming, you’ll get $25,000 when you sell them all back.

After completing it’s build in 4 hours, each KEM generates 2,000 XP (not including your XP multiplier or the 5x for activating your XP Collider). This ratio of in-game cash to XP is far superior to the 10:1 ratio of Bloodmobiles ($132,000 for 13,200 XP) and Rat Trap Delivery Trucks ($150,000 for 15,000 XP).

With your XP Collider activated, you can earn a lot of donuts depending on how many KEM you farm and what your XP bonus percentage is. The table and graph below show how many donuts you can earn based on how many KEM you farm and what your XP bonus percentage is when you are between Level 100 and 938, with an XP bar of 500,000.

(Note from Alissa: These tables are SUPER detailed…this is the best way to “display” them.  Click on them to make them larger, and see all the details….)



The table and chart look nearly identical at Level 939. However, as the XP requirements have doubled from 500,000 to 1,000,000 XP, the amount of donuts earned is halved. Below is the table for donuts earned at Level 939.

Now the biggest difference with KEM farming versus Bloodmobile/Rat Trap Delivery Truck farming is that you don’t lose any money if you farm the ideal number of KEM. But how do you know what the ideal number of KEM to farm is?

The ideal number is one that maximizes XP whilst minimizing change in income.

In order to not lose money whilst maximizing XP, the amount of income you earn in four hours should equal the amount of income you spend on KEM. Your income whilst farming will come from two main places: 75% will be generated by your characters and buildings while 25% will come from selling the KEM you farm. To illustrate how many KEM to purchase, I will use my own situation as an example.

In order to calculate how much income I earn in four hours, one morning I woke up cleared all character tasks and building incomes. I then sent all my characters on a four hour task. At this point, my in-game cash was $1,240,920. I then returned four hours later, cleared all character tasks and building incomes. My income was now $1,393,900. So my four hour income is $152,980.

So let’s say every four hours my characters and buildings earn $152,980. This will account for 75% of my income whilst KEM farming, as the other 25% will come from selling the KEM you farm. So we take this $152,980 and multiply it by 4/3 to account for the other 25%. $152,980 x 4/3 = $203,973. So $203,973 is how much money I should spend to farm the ideal number of KEM for me.

Now that I know my four hour income and ideal number of KEM to farm, I can turn on my XP collider and start KEM farming.

For $203,870 I can purchase 32 KEM for farming (if I only have one in my town at baseline). So 32 is the ideal number of KEM I should farm. So lets say I spend $203,870 farming 32 KEM. While those 32 KEM undergo their four hour build, I send all my characters on a four hour task. When I come back four hours later, my characters and buildings will again earn $152,980. And when I sell those 32 KEM, I’ll earn $50,968 (25% of $203,870). So my four hour total income is $152,980 + $50,968 = $203,948, while my expense on 32 KEM is $203,870.

In summary, after a four hour round of KEM farming, I had no significant change of in-game cash (gained a measly $78), but at the same time gained some major XP from 32 KEM (a base XP of 64,000 or 320,000 with the XP collider turned on, not including any bonus percentage). Now I’ll continue doing this every four hours, amassing large amounts of XP, yet not losing any in-game cash.

Depending on your ideal number of KEM and your XP bonus percentage, you can be earning multiple donuts every four hours. At 25 donuts to activate the XP collider for 10 days, even if you only have the time to earn three donuts a day farming KEM, you will have a net profit of donuts every ten days, without losing any in-game cash.

Well, I hope this comes as good news for some of you and something to look forward to for others.  I know not everyone has a huge bankroll of in-game cash, and have been looking for alternatives to Bloodmobile/Rat Trap Delivery Truck farming. What are your thoughts about KEM farming? Have you already been using the technique? What is the ideal number of KEM you can farm? What is your bonus XP percentage? Sound off in the comments below. You know we love hearing from you.

  1. Thank you! Just started KEM farming and I have recouped the 25 donuts XP Collider investment in 24 hours. Onwards and upwards!


  2. Does the xp collider increase apply to base xp earned or base xp + bonus percentage?


  3. Can’t the two methods be combined? I farm 16 KEM every 4 hours without xp collider, but I earn more $ than those KEM cost. I save up my earnings and then farm as many KEM as I can with collider on (requires lots and lots of land). This way I farm cheap KEM (up to 3000) while saving xp collider donuts for farming the expensive ($14400) KEM


    • That is exactly what I did to get started, cheap KEMs without the collider while I banked money, then brief spurts of mega-farming with it. As a short term strategy, it works well, but it doesn’t take long to get enough bonus% that your normal tapping (non-farming) with the collider will provide more than the 25 donuts needed for the collider every 10 days. At that point, it makes sense to keep it charged up all the time.


    • When you have the collider constantly on you get the XP benefit from characters and rent (and other activities). Many have found it is just easier and more beneficial to just have the collider on constantly, buying 10 days for 25 donuts. On one of my games I level up twice (6) donuts just collecting rents and from characters. So even if I visit only once a day that is 60 donuts for the 10 day period. Once you get your bonus up to a certain level you will just leave the collider on.


  4. Thank you!!!!
    As always, TSTO’ers are AWESOME!!
    (And a huge thank you to my neighbors for not dumping me, I couldn’t visit because I was with my son in the hospital)

    I just love love love this site 😃❤️😃❤️😃


  5. I am very interested in KEM/collider farming for donuts but I have ZERO tech skills and reading those charts (while simply amazing!!!) is very hard for me.
    Has anyone posted a ‘farming for dummies’ version so I can ‘farm’ too?
    Thank you!!!


  6. Necromancer Nightmare

    Does selling the KEMs give experience? I admit I’m lost on the concept of why you sell the KEM. Since buying them seems to increase their cost for next purchases wouldn’t you just buy them once and leave them out? Or is the sale necessary for the farming?


    • The selling of the KEMs is absolutely necessary! You buy the next batch of KEMs to earn XP and then it is rinse and repeat.


    • Yes. Essentially, you are exchanging money for XP, and buying KEMs are the most cost-effective medium we have found for doing that.

      Later, when your bonus % reaches an obscene level like mine has, money will no longer be an issue and you can use other items that are more time-efficient, but cost more.


      • Once you sell the ones you just bought (keeping the original one), the price-per-KEM reverts, and starts over again at the lower price before escalating again as you buy. So it saves money, and land – you’d fill up all your land pretty darn quick!


  7. Does anyone know if it´s better to own/buy Brown Houses VS KEM stores?? If one is a frequent player, meaning you log on periodically throughout the day.


    • KEM is for XP. For KEM farming, you need to sell all (but one) KEM to get the best value ($220 for the first vs $14,400).

      For generating cash Brown houses are valuable if you visit a lot. A 10-15 minute visit can generate 3 collections. If you visit every 4 hours they can return more than others houses depending on the price of the next house (brown houses top out at $17,300).

  8. I started a new “B” town for the heck of it. Only on level 9 or so right now. Is the XP Collider available at a certain level? Or do I have to wait around for it to be offered again at some point? Thanks!

  10. Does the elite yacht club and ocean suite have hidden xp?


  11. I need some help please…
    I took out of my storage all the springfield heights buildings that provides xp, I fully upgraded all(5) the beach hideaway, besides that I have 133.75% and I am at level 187.
    It takes me 13 kem to level up. And with the cash that I can generate I can buy about 26 kem every 4 hours. Therefore, I make 2 donuts every 4 hours. It seems pretty low…
    Should it be higher than 2 donuts every 4 hours ??…?


  12. Looks like they raised the base price of KeM. Bummer.


  13. This has got to be one of the geeky-est TSTO articles I have read – and I bloody love it!!!
    Will be saving this to my faves and reading up properly later on x
    THANK YOU!!! 🙂

  14. Is it not better to buy some other building along with kem, once the price of kem gets closer to 10k? Like Brown houses?


    • You buy KEM for the XP generated from building them. Then you sell them for 25% and then buy again. With brown houses, etc you buy them for cash and XP they generate over time.


    • Not really. There seems to be a correlation between what you get when building and what you get from tapping; that is, the crappier the reward for TAPPING a building once it’s built, the better the payout for building it in the first place, and vice-versa. KEMs seem to have the best build cost to initial XP ratio that I’ve seen, although it’s been a while since I checked brown houses specifically.


    • buying other buildings it’s waste of time

  15. Below is my step by step progress which I believe proves the benefits of KEM farming, at least below level 939.

    In 156 days went from level 7 to 939, 2.75% bonus to 246% bonus. Played the events while doing regular level up tasks. Completing all not involving premium characters or items, including Krustyland. Just short of completing Friendship level 20.

  16. Thank you so much Safi. I have accumulated over 1000 donuts with this and they are increasing every 4 hours. I tend to go overboard with this new found power and have a lot less cash than before. However, I have been playing this since the beginning so I have lots of cash to spend.
