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.

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

7 bucks to nuke Ohio is a great deal if you ask me
how to spend 7.6 hours wisely
Nobody in scary uniforms knocked on my door while I was playing; which was disappointing. Otherwise great way to spend three hours walking back and forth innocently.
YOU GET TO BE TEMU OPPENHEIMER!!!! WOOOOOOOOOOOO!!!
Good premise, questionable execution. Yes, it's wacky and absurd, with some quirky dark humor, but that's about where the positives end. The gameplay can basically be boiled down to assembling one giant project piece by piece, whether it's a treehouse, an atom bomb, or a black hole. I kept expecting some kind of upgrade system to speed things up or make the process less tedious, but no. It's the exact same routine repeated over and over again. Not to mention the janky physics occasionally cause your stuff to clip through the floor, forcing you to question your sanity and buy replacements - plus the search feature doesn't even work in the online shop. In the end I guess it does have some educational value - never try to build an atom bomb in your garden, you'd probably die of boredom long before your creation has a chance to kill you.
10/10 Cuz I got asked to leave this review
Not having a save game system is insane for how much busy work you have to do. My pc crashed and 2 hours of moving ♥♥♥♥ from point A to B was gone. kind of just a work simulator. Its cool but i cant recommend this.
Fun concept but there are many aspects that make it incredibly grindy such as no way to make money or save mid stage. Developer has stated in Steam forms they do not intend to fix. I would not recommend unless you can dedicate multiple uninterrupted hours to a single session. There are also lost of aspects of the game that could do with a good polish.
Ferb I know what we going to build today
