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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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.

a best fun and creative game i have ever played. i think some one is roste by this game. thank you
Luego de perder absolutamente todo mi dinero apostando y tener que volver a empezar la partida desde cero, puedo decir con total certeza que las 3 horas de juego valieron completamente la pena. El juego está lleno de momentos cómicos absurdos (como terminar arruinado por culpa de las apuestas antes de poder terminar el proyecto) y, al mismo tiempo, las mecánicas tienen ese toque de "realismo" que hace que todo sea todavía más caótico y divertido. Totalmente recomendado si quieres sentir la experiencia completa de armar algo potencialmente destructivo en el patio de tu casa mientras tu vida se desmorona por malas decisiones.

GOOD GAME
10/10 will never recover from this being over
Really good game! 9/10. A couple things could improve. My Delivery guy put stuff on my roof and i couldnt get it. But it did say not to order a lot at the same time so i guess my fault. But nonetheless, It was a really fun game!

THIS WAS A LONG AND FUN GAME {GAME HAD ME LEAVE A REVIEW}
This game is so ridiculous, but so fun! It isn't every day you get to build an atomic bomb in your backyard and wipe out an entire city!
