The Mystery Box is a premium item that you can purchase for 6 donuts or you can get it for free every 5 days, as a bonus for playing the game every day. The Mystery Box could contain a premium item or it could contain a non-premium item, which one it reveals to you truly is a Mystery.
The Mystery Box is typically one of those premium items I would tell you not to purchase and save your donuts, unless of course you’re desperate for a Lemon Tree (the Mystery Box is the only way to get one), because you can earn one every 5 days and there’s no guarantee of a premium item. However, for those of you purchasing the Mystery Box, or just curious about what might be inside of yours every 5 days there are a few things you should know.
With the Mystery Box there’s a game going on behind the scenes, (pretty much like all games of chance) every time you either buy a Mystery Box for 6 donuts or collect one as a daily reward. The game internally generates a random number and each item available through the Mystery Box has a number assigned to it. The prize you win is the item that has the first number that’s greater than the random number generated.
So what are the prizes you can win in a Mystery Box and the Odds of winning them? Here’s a complete breakdown of your chances:
| Prize | Odds |
| Mystery Box | 10.98% |
| Lemon Tree/$250 | 10% |
| Parking Lot | 10% |
| Brown Fence | 10% |
| Tree | 10% |
| Large Hedge | 10% |
| Newspaper Dispenser | 10% |
| Picket Fence | 4% |
| Gazebo | 4% |
| Angel Topiary | 4% |
| $500 | 4% |
| Premium Bench | 4% |
| $1,000 | 4% |
| 10 Donuts | 2% |
| Squeaky Voice Teen/30 Donuts | 2% |
| Homer Buddha | 1% |
| $2,500 | 0.01% |
| 30 Donuts | 0.004% |
| Tire Fire/40 Donuts | 0.002% |
| Lard Lad | 0.001% |
Of course it’s all a matter of luck –and I did win my Squeaky Voice Teen via the Free 5 Day Mystery Box when I first started playing.
What’s the best thing the Mystery Box ever awarded you?
Update: On April 1st, 2015 EA rolled out a new Mystery Box. Basically the same concept, just with a new look and some new items added. Here’s a look at what happened with that:
There was a new look to the box icon. It now looks like this:
Same concept, however. Spent 6 donuts…or wait once a week for your Daily Play Bonus and get one for free..and open a Mystery Box for a chance to win some cool Premium items, and some freemium duds.
There is an end date indicated in the files of April 30th, 2015. However, it’s not indicated if this is the end date for the new box or just the end date for the free box awarded with the initial questline. (You should be awarded a free box between April 1st and April 30th, 2015, after a some dialogue between Mr. Burns and Smithers. You can view more about that on this post) Once April 30th hits, and we know for sure what will happen…we will update this post with the details. Update: It appears that my initial prediction was correct and April 30th just marked the end of the free Mystery Box initial questline. So the new Mystery Box contents are here to stay!
Here’s a look at what’s inside the new box:
| Item | Unique? | Value |
| Khlav Kalash Stand | No | $760 |
| Minnow Pond | No | $4,500 |
| Bomb Shelter | No | $5,600 |
| Chalmer’s 1979 _ONDA | No | $9,800 |
| 10 Donuts | No | 10 Donuts |
| 30 Donuts | No | 30 Donuts |
| Squeaky Voiced Teen | Yes | 30 Donuts |
| Channel 6 News Van | No | 40 Donuts |
| Itchy & Scratchy Billboard | No | 40 Donuts |
| Tire Fire | Yes | 40 Donuts |
| Kearney | Yes | 60 Donuts |
| Blue Haired Lawyer | Yes | 90 Donuts |
| Lard Lad Donuts | No | 110 Donuts |
| Lemon Tree | Yes | n/a only way to get is the box |
Note: We’ve decided against posting the odds for the revised boxes..and here’s why. First, there’s a ton of conflicting information out there about it. Some are saying one set of odds, some are saying another. There’s one version that we follow from the files…HOWEVER. It’s more complicated than saying you just get this ____ % of the time. There’s a script it follows, that basically says if you don’t get ____ than you have ____ % chance of getting ____. And moves down the line like that. So because it’s conflicting and confusing information. We’ve decided not to post the odds. Just enjoy the free boxes that you get & don’t worry about what the odds say you’ll get.
Hope that helps you get a better understanding of the Mystery Box!
