An absurd backyard bomb-building simulator. Raise funds, plan your approach, hunt down rare parts, and assemble your atomic masterpiece while staying calm and avoiding suspicion from nosy neighbors and federal agents.

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 4.29/day in the week to Sep 8 → 7.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
It’s a quiet Sunday morning. You're relaxing in your backyard when it suddenly hits you:
You need to build an atomic bomb.
Naturally.
In this absurd single-player simulation, your peaceful suburban life takes a wild turn as you attempt the most questionable DIY project imaginable. Building a nuclear bomb in your backyard might not be the hardest thing you’ve done but it’s definitely the weirdest.

To complete your creation, you’ll need to:
Raise funds via a chaotic mini-game that tests your charm and hustle.
Go shopping: Bid on auctions and scour regular online stores for those oddly specific blueprint parts.
Do the math: Turn everyday household objects into actual atomic equations.
Extract critical materials from totally unrelated household items.
Assemble everything with precision... or at least, something close to it.
Handle your nosy neighbors, who are just a bit too curious.
Avoid IRS scrutiny, because spending your fundraiser money on plutonium raises red flags.
Manage your stress using strange and increasingly unhinged coping mechanisms.

The game is split into three major stages of building, each bringing its own unique challenges that will test your patience. Complete all three to finish your project ideally without any accidents along the way.
Disclaimer:
Some elements in this game are inspired by real-world nuclear formulas. Do not try this at home. Do not be inspired. Seriously.

我觉得这个游戏很好玩,但是我每次买到新的东子时,我的盒子每次飞来飞去,哎呀。
Sehr witzige Abwechslung, an einigen Stellen etwas langweilig durch Wiederholungen der Tätigkeit, aber dennoch sehr interessant gehalten. Für den Preis denke ich, ist es in Ordnung den Dev zu supporten. Da steckt viel Motivation drin und es hat potenzial zukünftig noch einen drauf zu legen. Ich hoffe in Zukunft kommt mehr oder vlt auch ein DLC.

Fun Game, different than what i'm used to but funny
Gutes Spiel
from all of my experience in bombing the US of a and making atomic bombs in my back garden, i can happily say this game is extremely realistic. i also like the added neighbour who is nosey. this was the case when i was building my first explosive device. after a few, they stopped caring. i hope the developer soon releases a game called 'how to make an IED in your backgarden. that would be a game i will be able to relate to a lot.
I never thought I could have built a bomb but here I am. The price of this game was so worth it. I'm definitely preordering the next one if there will be another.
