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.

Built atomic bomb 10/10
The game is as advertised. Using every day items you purchase off the internet, you build a nuke in your back yard. You converse with a nosy neighbor, you talk to your wife, you smoke, you knock back a couple cold ones, and you get to work. And, because your neighbor can't mind his own business, feel free to dispose of anything left over by tossing it over the fence into his yard. The collision physics on this are a little wonky sometimes. The assets used are ridiculous, but the game kills a few hours. Worth the money spent. Hopefully, the dev has something else up their sleeve.

Değişim ama ilginç bir oyun mekanikleri bazı yerlerde tuhaf geliyor düzeltilmesi gereken yerler var ama şimdilik gayet başarılı
nagyon jó játék és unalom űzésre is tőkéletes, DE SENKI NE PRÓBÁLJA KI OTTHON!
I really love fun little gimmick games like this. Its a simple task with simple mechanics, build an Atomic Bomb.... The game is filled with a random jokes and works really well with the overall vibe of the game. Looks wise its quite nice and works really well with the game, definetively a fun little game if you want to blow off 2-4 hrs of your time.
