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.

Reviews
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.
great game

ABSOLUTELY AMAZING GAME BEST 16 HOURS IVE EVER SPENT 100/10
"Now I am become Death, the destroyer of worlds" J. Robert Oppenheimer July 16, 1945
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
Deutsch Die Idee vom Spiel ist echt gut. Die Gespräche mit den Nachbarn, deiner Alten oder mit "ChatGPT" sind teilweise echt witzig – aber das war's dann leider auch schon. Den Großteil der Zeit rennt man einfach nur mit Kisten durch die Gegend und macht immer wieder dasselbe. Das wird echt schnell eintönig. Dazu kamen bei mir noch einige nervige Bugs. Mehrmals ist einfach mein Fadenkreuz bzw. das HUD verschwunden. Dann durfte ich erst mal wieder herausfinden, wie der nächste Schritt überhaupt war. Noch schlimmer war, dass mir öfter Gegenstände einfach verschwunden sind oder sich plötzlich selbstständig gemacht haben. Auch die deutsche Übersetzung ist an einigen Stellen ziemlich holprig und manche Beschreibungen helfen einem überhaupt nicht weiter. Ach ja... speichern. Stimmt ja, geht quasi gar nicht. Ich glaube, dazu muss man nicht viel sagen. Das Spiel hätte echt Potenzial, aber in dem Zustand macht es sich das leider selbst kaputt. Müsst ihr wissen. Schneemobil PS: Ihr schleppt in dem Spiel mehr Kisten, als mein Sack Spermien produzieren kann. English The idea behind the game is actually really good. The conversations with your neighbors, your wife, or "ChatGPT" are pretty funny at times—but that's unfortunately where the positives end. Most of the game is just running around carrying boxes from one place to another and doing the same things over and over again. It gets repetitive really fast. On top of that, I ran into quite a few annoying bugs. My crosshair and HUD disappeared multiple times, so I constantly had to figure out what the next step was all over again. Even worse, items would randomly disappear or suddenly decide to move around on their own. The English translation might be fine, but the German one definitely isn't. Some descriptions are also so unclear that they aren't helpful at all. Oh, and saving... right, you can barely do that. I don't think I need to say much more about it. This game really has potential, but in its current state it's just getting in its own way. Your Call Schneemobil PS: You'll carry more boxes in this game than my balls can produce sperm
