A free bomb defusal game needs less than most groups expect: two to five people, a web browser on two devices or one device plus a printed manual, and a way to hear each other. Bomb Appétit costs nothing, installs nothing and asks for no account, so the first round can start within minutes of deciding to play.
What a free bomb defusal game needs on the table
A free bomb defusal game like Bomb Appétit needs four things on the table: two to five players, one device for the bomb, a second device or a printout for the manual, and a way to talk. There is no download, no purchase and no sign-up between those four things and the first countdown.
Players. The smallest group is two people and the largest is five. One player is the Defuser, who sees the bomb. Everyone else is an Expert, who reads the manual. That makes one to four Experts. A group of six or more can rotate, with someone sitting out each round and swapping in for the next.
A bomb device. The Defuser needs a browser with the game open on Play. The bomb has the most to look at, so it belongs on the larger of the screens you have. A laptop or a tablet suits it well, and a phone works too.
A manual. The Experts need the manual. It lives on the same site, at its own address, and opens on any device. It can also be printed from the browser, which turns a one-screen household into a working setup.
A way to talk. The game has no voice chat of its own. In one room, that is not a problem: everyone just talks. When players are apart, they need a phone call or a video call running alongside the game.
That is the whole list. People who look for games they can play without downloading anything usually want exactly this: a link, a few friends and nothing to set up. A defuse a bomb online game in the browser fits that well, because every part of it, the bomb, the manual and the online rooms, runs on a web page.

Is the bomb defusal game free, and what does signing in add?
Yes, Bomb Appétit is free to play, with no paid tier and nothing locked. Guests can play every mission, freeplay bomb and manual without an account. Signing in with GitHub adds the ranked side: your verified runs go on the leaderboards, and a dashboard shows where you stand.
There is no premium edition held back either. Every mission, every module and every rule seed is in the free game, and signing in unlocks nothing that costs money. The game is meant to be played by whole groups, and a paywall in front of one Expert would stop the whole table.
Here is what a guest gets with no account at all:
- Every mission, from the first one-module bomb to the largest case.
- Freeplay, where you build your own bomb.
- The manual for any rule seed, on screen or printed.
- Online rooms with five-letter codes for playing far apart.
- Both the 2D and the 3D bomb views.
Signing in changes what happens after a defusal, not what you can play. Each mission has its own leaderboard. A signed-in player is listed once per mission, by their best verified defusal: the most time left on the clock, then the fewest strikes, then the earlier run. Your rank also appears as a percentile, such as "Top 12%", on the missions page, the results page and your dashboard.
The word "verified" matters. When a bomb ends, the Defuser's browser sends a log of every action. The server replays that log with the same game engine on the same bomb. If the replay does not end the same way, the run is not listed. Guests play exactly the same bombs. Their runs are just not ranked.
So the honest answer to "is it really free?" is yes, and the only reason to sign in is if you care about where your team stands. Plenty of groups never do, and they miss none of the game.
Two screens, one screen and a printer, or phones only?
Two screens is the easiest setup, with the bomb on one and the manual on the other. One screen and a printer works just as well for a group in one room. Phones only also works, as long as the Defuser accepts a smaller bomb. The table compares four common setups.
| Setup (example) | Defuser uses | Experts use | Note |
|---|---|---|---|
| Laptop plus phone | The laptop, for the bomb | The phone, for the manual | Works best for most pairs. The bomb gets the big screen and the manual reads well on a phone. |
| Laptop plus printed manual | The laptop, for the bomb | Printed pages | Good for a group in one room. Pages can be handed out so each Expert holds a few modules. |
| Two phones | One phone, for the bomb | The other phone, for the manual | Works anywhere. The bomb is smaller to handle, so the Defuser should describe slowly. |
| Tablet plus laptop | Whichever screen is larger | The other device | Comfortable for both seats. Put the bomb on the larger screen. |
The rows are examples, not a full list. The rule behind all of them is the same: the bomb and the manual must never share a screen, and the bomb should go wherever there is more room.
Paper deserves a note. The manual is laid out to print cleanly in black and white, and every color in it is named in words, so a black and white printer loses nothing. A printed manual also makes it easy to split the pages between several Experts. The guide to printing the Bomb Appétit manual covers the whole process, and its section on printing the manual from the browser shows which command to use.
Paper has one catch. A printed manual belongs to one rule seed, and the seed is printed on it. Before every round, check that the number on the paper matches the number on the bomb. Seed 1 is the standard manual, so a group that always plays seed 1 only has to print once.
For two people, the laptop plus phone row is usually the right one. The guide to setting up a two-player game with one Expert goes into how that pair should pace a round.
Which browsers and devices run the free game?
Bomb Appétit runs in any recent version of Chrome, Firefox, Safari or Edge, on a computer, a tablet or a phone. Nothing is installed. The bomb is easiest to handle on a bigger screen, while the manual reads well on anything, so put the bomb on the largest screen in the room.
The bomb comes in two views, 3D and 2D. Both show the same bomb and play the same way. The game's changelog puts the choice simply: pick whichever your device likes better. If the 3D view feels slow or cramped on a phone or an older laptop, the 2D view is the obvious switch.
The Experts' devices have an easier job. The manual is a plain page of text and tables, so any phone or tablet that can open a website can show it. Each Expert can open it on their own device, which also means two Experts never fight over one screen.
Playing far apart uses the same browsers. The host opens Play, creates a room and shares its five-letter code. Everyone else joins with that code, and each player picks Defuser or Expert, with one Defuser per bomb. If you have not done this before, the guide to how a room code connects browsers far apart walks through it.
In an online room, Experts still never see the bomb. Their screens show the time left, the strike count and how many modules are solved, alongside the manual. The bomb stays on the Defuser's device alone.
The questions above are also collected on the FAQ page, which is a good link to send a friend who asks "what do I need to install?" The short answer is a browser they already have.
The setup mistake: one device for the bomb and the manual
The most common setup mistake is putting the bomb and the manual on one device, in two tabs or side by side. It looks efficient and breaks the game. Whoever looks at that screen sees both halves, so nobody has to describe anything, and the round turns into one person solving a puzzle while others watch.
The manual itself warns against this. Its description tells the Experts to read it aloud and never show it to the Defuser's screen. The bomb works the same way in reverse: the Experts should never be able to see it. One shared screen makes both impossible.
There is a practical cost too. A Defuser switching between tabs loses sight of the countdown and the module they were working on. Every switch costs seconds that the timer keeps counting.
The fix is almost always close at hand:
- Borrow a phone. Most groups have at least one phone that is not in use. Open the manual on it.
- Print the manual. One printout of seed 1 serves every future game, as long as the seed stays the same.
- Use separate devices online. If the group is apart anyway, each player opens the game on their own device and joins the room.
A related mistake is an Expert peeking at the bomb device because it happens to sit on the same table. Turn the bomb screen away from the Experts before the countdown starts.
Once the devices are sorted, it helps to know what the Defuser is looking at. The guide to the Defuser's seat covers the case, the timer, the strike lights and the module panels, so the person holding the bomb knows what to read out first.
