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.

Had to leave a review (Totally not rigged...) Fun little game, missing a save function, but otherwise fun.
Non sono solito lasciare recensioni negative e, considerando che l'ho pagato meno di 10 euro, non mi aspettavo certo un capolavoro. L'idea di base è anche simpatica, ma purtroppo la realizzazione mi ha deluso. Ho trovato i comandi poco piacevoli, l'assenza di un sistema di salvataggio piuttosto frustrante, e la poca interattività, insieme agli oggetti disseminati un po' a caso, il sistema di acquisti e di "upgrade". Anche le spiegazioni sono spesso scarse e alcune azioni, ripetitive finiscono per essere solo una perdita di tempo. L'umorismo ci prova, ma proprio non arriva ad apparare la bilancia. Insomma, mi aspettavo qualcosa in più. Alla fine più di tutto mi è rimasta la sensazione di non essermi divertito.

Fun little game, would be better if there was slightly more content. Maybe random scenarios depending on what dialogue options you choose with NPC's. A little buggy with the physics and collision causing stuff to fly away but all good. I only had one problem, all my cans of water disappeared. Would recommend.

No me gusta trabajar -gracias
I mean its aight like, make the bomb and allat. Not bad, i will say. This is aight tho
Booom.
good game
Part 1: - Nails hitbox is smaller than my will to live. Part 2: - No save file. I spent 7 hours of my playthrough JUST on the second part of this game because of this issue alone. Had to restart the whole section 5 times. - The way you pickup items means you can just have them glitch randomly into places you can't get them back from. I had glitched the RDX into the dryer and couldn't get it out because of how flimsy it was to pick up items. This caused me to be softlocked. - Your Green/Red meter can go past being full and get glitched at red 24/7. Part 3: - The flashing lights of the welders hurts my head/makes me feel sick and could cause seizures. Can there be an option to remove the welders flashing lights? - If you smoke and then pick up the welder, "Thankyou for smoking" is stuck on your screen permanently. - Having to click all of those wires in individually made me realise how much I love torturing myself for video games ♥♥♥♥♥♥♥♥♥. Overall I liked the game, it was really fun once you knew what you were doing. The jokes were funny, The achievements were funny and the "spin to leave an achievement" at the end was also fun. I would 100% buy and play another game like this if it was ever developed. 10/10.
