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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

YOU GET TO BE TEMU OPPENHEIMER!!!! WOOOOOOOOOOOO!!!
This game was difficult yet rewarding. While a task such as this may seem impossible in the middle of it all, there is a light at the end of the tunnel, I promise...a very bright, explosive, radioactive, fatal light, but a light, nonetheless. I highly recommend this game. It is mentally strenuous but definitely worth it.

this is another one where I wish there was a neutral option. It was mildly amusing, although I wish it leaned into the jokes more, but there were some absolutely tedious moments... The game seems like it has some commentary to make about nuclear weapons, but chickens out. I agree basic features like even saving settings (you always have to reset the y inversion and jump scare option... not sure what that's even about... but any time you start a new game, you have to reset those settings). If it wasn't so buggy, I would probably recommend this game. There is a lot of work, but if you've ever played Farm Simulator or similar, it's not THAT much work... but it could be better (IDK why you couldn't fill both molds...). But when you open a box and it shoot across the yard because you opened the box while holding it... Also, when you first start, invest all your money in the stock market so you can buy the blackhole, if you lose all your money, just restart the game. That makes the game a LOT more fun. [spoiler] Also, the end was rather disappointing... it would have been nice if there was some kind of explosion animation... Although, it was rather realistic I suppose.[/spoiler] For less the the price of a movie ticket, I was mildly amused for longer than most movies, although, I was annoyed at some parts.
I can now build an atomic bomb in my garden 100% recommend for anyone looking to do the same
Im 18 minutes over the refund timer after finishing the game....
7 bucks to nuke Ohio is a great deal if you ask me
10/10 Cuz I got asked to leave this review
