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.

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.

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.
Im 18 minutes over the refund timer after finishing the game....

Two irradiated thumbs up. My CIA Agent enjoyed watching me play this game. Would go bowling with a Demon Core again.
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.
Drank beer, smoked a cigar, then detonated my neighborhood. 10/10
Sehr geehrte Damen und Herren, hallo allerseits! Ich rede in dieser Rezension über die schlechten, sowie die guten Dinge in dem Spiel "How to Make an Atomic Bomb in Your Garden". Unten geht's weiter, Es gibt auch eine englische Version unten - Pluspunkte: Die deutsche Übersetzung ist meiner Meinung nach sehr humorvoll gestaltet. Das Spiel hat auch eine gute Grafik - Kritikpunkte: How to Make an Atomic Bomb in Your Garden. Das ist, was man in diesem Spiel lernt. Abgesehen davon gibt es aber auch noch eine Menge andere Sachen in diesem Spiel, zum Beispiel Kisten. Es gibt auch Kisten. Habe ich schon Kisten erwähnt? Es gibt auch die Schlepp-Mechanik - jeder Gegenstand in dem Spiel spawnt erstmal vor deiner Haustür - wünschte ich zumindest. Es spawnt tatsächlich irgendwo in der Nähe deiner Haustür! Ich bin kein großer Fan davon, also so gar nicht tatsächlich. Man kann in diesem Spiel auch eine Menge laufen, da man diese Sachen dann alle vom Hof in den Garten schleppen muss; also muss man nicht, ich zum Beispiel habe das Spiel zurückgegeben (das tu' ich mir doch nicht an). Man kann zwar ein schwarzes Loch kaufen, wo man nur noch die Items einzeln alle reinwerfen muss, stellt sich aber heraus, dass die danach mit einer 50/50-Chance despawnen, das habe ich selbst herausgefunden. Man darf in diesem Spiel auch eine Menge links- und rechtsklicken, was mir persönlich nicht so viel Spaß macht. Man muss so viel in diesem Spiel gleichzeitig machen, was ich nicht toll finde. Man wird von Aufgaben direkt nach Sektion 1 überrumpelt mit Sachen, die man bestellen muss, dass ich erstmal die von der nächsten Seite bestellt habe_ und dann gemerkt habe, dass ich erst das von der vorherigen Seite bestellen muss. Dies wurde mir aber leider nicht mitgeteilt, stattdessen habe ich das auch erst im Nachhinein herausgefunden. Ich finde es tatsächlich sehr schade, da das Spiel sehr viel Potenzial bietet und es durchaus Spaß hätte machen können. Zu schade, dass die Controls und die Gameplay-Mechaniken so sehr verhauen wurden. Müsst ihr wissen, Pro6603 ENGLISH VERSION: Ladies and gentlemen, hello everyone! I’ll be talking about the bad as well as the good things in the game "How to Make an Atomic Bomb in Your Garden" in this review. Read on below! Pros: In my opinion, the German translation is written with a great sense of humor. Cons: How to Make an Atomic Bomb in Your Garden. That is what you learn in this game. But aside from that, there are also a lot of other things in this game, like crates, for example. There are also crates. Did I mention crates yet? There is also the hauling mechanic—every item in the game spawns right at your front door first—or at least, I wish it did. It actually spawns somewhere near your front door! I'm not a big fan of that, like, not at all, actually. You also get to do a lot of walking in this game, since you have to drag all these things from the yard into the garden; well, you don't actually have to, I for one refunded the game (I'm not putting myself through that). Sure, you can buy a black hole where you only have to throw the items in one by one, but it turns out they have a 50/50 chance of despawning afterward, which I found out myself. You also get to do a lot of left- and right-clicking in this game, which personally isn't that much fun for me. You have to do so many things at the same time in this game, which I don't really like. Right after section 1, you get completely overwhelmed with tasks and things you need to order—so much so that I ended up ordering the stuff from the next page first, only to realize that I had to order the things from the previous page first. Unfortunately, the game didn't bother telling me this; instead, I had to find that out the hard way afterwards, too. I actually find it a real shame, as the game has a lot of potential and could have definitely been fun. Too bad the controls and gameplay mechanics were butchered so badly. Your call, Pro6603
Ferb I know what we going to build today
