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 2,419 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.

Some elements in this game are inspired by real-world nuclear formulas. Do not try this at home. Do not be inspired. Seriously.

Fix the hammer and bugs I literally couldn't do anything after my hammer got flung. Other than that the game is pretty fun for that one part when my hammer didn't decide to disappear on me
One of the best sim games i've played and may have learned how to make a nuclear bomb in my backyard, good for any other pyromaniacs and uraniumheads out there 10/10
Was für ein bombastischer Spaß! Dieses Spiel hat alles, was sich ein potenzieller Atombombenbauer wünscht! Realistischer Zusammenbau einer Nuklearen Schönheit, eine Ehefrau, die den ganzen Spaß vom Fenster aus beobachtet und ein Nachbar, der einem permanent auf den Sack geht und das ganze Projekt von Anfang an stalked! Insgesamt aber wirklich lustig und unterhaltsam. Kleiner Tipp - Kauft euch das schwarze Loch! NUR LIEBE!
absolute peak game design, best 3.5 hours of my life
Es war Ok. Wie viele andere schon geschrieben haben besteht keine wirkliche Herausforderung und ich hatte mir auch mehr erhofft von dem Spiel, es läuft alles nach Anleitung und so ziemlich Deppensicher. Der Humor ist stellenweise ganz ok aber so wirklich vom Hocker reißen tuts einen nicht. Dass das "Savegame" nur als Etappe gespeichert wird und nicht mit dem aktuellen fortschritt ist bei der (nicht vorhandenen) Komplexität des Spieles Verschmerzbar. Wünschenswert wären noch 1-2 Content-Updates, da das ganze dann doch recht linear und Monoton ist. Ein Perfektes Streamer-Gamer. Für roundabout 4 Stunden Spiel"spaß" 7€irgendwas ist in meiner Welt noch Fair. Wie geschrieben kommt da hoffentlich noch was an Content (so in richtung Komplexität, umwelt, etc.), so dass sich später ein neuer Spieldurchlauf vielleicht lohnt.
Stage two is still bugged, can't add ingredients to pot. Wish it was something solvable, but I have searched the entire map for the needed water, and restared twice.
I gambled for this Review. And unfortunately, I must go with the totally not rigged luck gods on this one. Was a funny game, def a good laugh to play with the boys on call. Join me in hating the wheelbarrow and refusing to use it after it deleted one too many items. Perfect 5/7 gameplay.
