> Online games to play with friends on different computers: which device suits the Defuser, which suits an Expert, and mixing laptops, tablets and phones.
Online games to play with friends on different computers work when the game lives in a browser rather than on one kind of machine. Bomb Appétit runs in any recent Chrome, Firefox, Safari or Edge, so a laptop, a tablet and a phone can share one bomb room. The device choice still matters: the bomb wants the biggest screen.

## Do online games on different computers need the same device?

They do not. Bomb Appétit asks each player for a recent browser and nothing more, so friends on a desktop, a laptop, a tablet and a phone can all sit in one room with the same five-letter code. Nobody installs a program, and nobody has to match anyone else's hardware.

The reason is how a room splits the work. One player hosts and creates the room, the others join with the code, and each person picks a role. The server then sends each browser only its own part. The Defuser's browser receives the bomb. The Experts' browsers receive the rule seed, which decides the manual, and a status line with the time left, the strike count, the modules solved and whether a needy module is awake. Experts never receive the bomb at all.

That split means two very different jobs for two kinds of device. An Expert's browser shows a page of rules and a few numbers, which almost anything can do. The Defuser's browser runs the game itself: it keeps the countdown, draws the bomb, takes every click and records each action with a timestamp so the server can replay the round later. So the useful question for a mixed group is not "does everyone have the same thing?" but "which of our devices should hold the bomb?"

A room seats one Defuser and one to four Experts, so a mixed group of up to five fits in a single bomb. The code is the only key to that room. Anyone who has it can join, which is why it belongs in a private message to your friends and nowhere public. What the code protects, and what other players can see once they are inside, is set out in [who gets into a private bomb room](/blog/multiplayer-browser-games-with-private-rooms-who-gets-in).

Once the room is open, every device sees the same round at the same moment. When the Defuser cuts a wire on a laptop, the solved count rises on an Expert's phone a moment later. When a strike lands, every status line shows it. The devices differ; the round does not.

## The Defuser's computer: why the bigger screen holds the bomb

The Defuser should take the device with the largest screen and a mouse or trackpad, which usually means a laptop or desktop. The bomb shows several modules at once, plus details on the sides of the case, and the Defuser must read all of it aloud without mistakes. Bigger glyphs and wire colors are easier to name correctly.

Think about what the Defuser actually does in a round. They describe each module so an Expert can find its page. They read the edgework, the serial number, batteries, indicators and ports printed around the case, because the manual's rules refer to those details constantly. They press, hold, cut and turn things on cue. Every one of those jobs gets harder as the screen shrinks.

The bomb also grows with the missions. The first mission, First bite, has a single module and five minutes on the clock, so a tablet copes fine. Later sections pack more onto the case: Back of house has eight modules and two needy ones, and Double shift uses a bigger case with fourteen modules and three needy ones. On a phone, a case that full means constant zooming and panning while the timer runs.

Two more things favour a proper computer for the bomb. The Defuser's browser is the one reporting status to every Expert, so it should sit on the steadiest connection in the group. And the round is a burst of focused work for up to fifteen minutes, so a laptop on mains power beats a phone at twelve percent battery.

There is a choice of views, too. The bomb comes in a 3D view and a 2D view, and the Defuser can pick whichever their device handles better. A strong laptop may enjoy the 3D case; an older machine often feels calmer in 2D.

### Five example friend groups and who takes the bomb

The groups below are invented examples, not survey data. Each row shows one sensible split for a mixed set of devices.

| Example group | Devices they have                                   | Bomb goes on                           | Manual goes on                | Reason in one line                                                          |
| ------------- | --------------------------------------------------- | -------------------------------------- | ----------------------------- | --------------------------------------------------------------------------- |
| Two friends   | A MacBook and an iPhone                             | The MacBook                            | The iPhone                    | The laptop shows the whole case; a manual page scrolls fine on a phone.     |
| Three friends | A Windows desktop, an iPad and an Android phone     | The desktop                            | The iPad and the phone        | A monitor holds big cases; the iPad shows a full module page at once.       |
| Four friends  | A Chromebook, two iPhones and an old Windows laptop | The Chromebook                         | The phones and the old laptop | The newest laptop runs the bomb; reading a page asks little of the old one. |
| Five friends  | Five laptops of mixed ages                          | The laptop on the steadiest connection | The other four laptops        | Every screen is big enough, so the connection decides.                      |
| Two friends   | An Android tablet and a phone, plus a printer       | The tablet                             | A printed manual              | The phone stays free for the call while paper holds the rules.              |

## An Expert on a different computer: tablets and phones for the manual

An Expert needs only enough screen to read one manual page comfortably, so a phone, a tablet or an elderly laptop is plenty. The manual is a plain web page that reads well on anything, and it prints cleanly too. Because Experts never receive the bomb, their device does a small fraction of the Defuser's work.

The manual has a simple shape. It opens with an introduction, then gives each module its own page, then ends with an appendix on edgework and a glossary. An Expert scrolling on a phone can jump between those parts instead of hunting, which matters when the Defuser says "it's the one with the flashing pads" and the clock is running.

A tablet is the sweet spot for this seat. Many module pages fit on one tablet screen, so the Expert can see a whole rule table without scrolling. A phone works too, with a little more swiping, and pinch-zoom helps on dense tables. An old laptop that would struggle with the bomb is perfectly happy showing text.

The manual must match the bomb. Every rule comes from a number called the rule seed, and rule seed 1 is the standard manual. In an online room, the room shares its seed with the Experts, so a manual opened from the room lines up with the bomb automatically. An Expert who opens a manual some other way, for example [manual 1](/manual/1) on a spare tablet, should check the seed against the room before the timer starts.

With two or more Experts, devices can shape the division of labour. The Expert on a tablet might own the modules with big rule tables, while the Expert on a phone takes the shorter pages. Everyone still sees the same status line, so nobody loses track of strikes or time.

Some groups have nothing but phones. That works, with a few adjustments to screen orientation, audio and notifications, all covered in [playing with phones only over a long distance](/blog/phone-games-to-play-with-friends-long-distance-phones-only).

## Can Mac, Windows and other computers mix in one room?

They can. The operating system does not matter, only the browser. Bomb Appétit supports recent versions of Chrome, Firefox, Safari and Edge on a computer, tablet or phone, so a Defuser on a Mac and Experts on Windows, Android and iPadOS play exactly the same round with the same rules.

The rules cannot drift between systems, because the manual is generated from the rule seed rather than stored per device. A seed of 1 on a Windows laptop produces the same manual as a seed of 1 on an iPad. The bomb is generated from its own seed in the same way. That determinism is what lets friends on different machines trust each other's screens.

It is also what keeps the leaderboards honest. When a round ends, the Defuser's browser sends its log of actions to the server, which replays the round with the same game engine before storing the result. A run is listed only if the replay ends the same way. So a defusal on a Linux desktop and one on a MacBook are judged by the same replay, and neither device gets an edge. Only signed-in players are ranked, and each mission has its own board, which you can browse on [the leaderboard page](/leaderboard).

Small differences between systems do show up, and they are about comfort rather than rules. Text may render slightly larger or smaller. Trackpads and mice feel different on a module that asks the Defuser to hold something down. Sound may come out of speakers on one machine and headphones on another. None of that changes what the bomb is or what the manual says.

The one practical rule is to keep the browser current. "Recent version" is the requirement, so a friend whose browser has been nagging about an update for months should accept it before game night.

## When a different computer cannot keep up

A device cannot keep up when the bomb stutters, the page will not load, or the Defuser keeps misreading small details. The fix is usually a swap rather than an upgrade: move the bomb to a stronger device, switch the bomb to its 2D view, or hand the weak device the manual instead.

The warning signs are easy to spot in a practice round. Animations lag behind clicks. The case takes a long time to appear. The browser warns that it is out of date and cannot be updated. A phone gets hot and dims its screen. Any of these on the Defuser's device is worth fixing before a timed mission; on an Expert's device they rarely matter, because a manual page asks so little.

Work laptops add a different kind of limit. A managed machine may block new sites, or its browser may be locked to an old version by an administrator. If that is the only big screen in the group, try the bomb on it once before the evening, and keep a second plan ready.

Screen size is its own edge case. A phone can hold the bomb for the early missions, but a full case with needy modules is a lot of detail for a few inches of glass. If the only large device belongs to someone who would rather read the manual, ask them to take the bomb anyway for the bigger missions, then rotate for the small ones.

Paper is the last resort for a device that will not cooperate at all. The manual prints in black and white from the browser's print command, so a friend whose tablet died can still read rules from pages. Check that the seed printed on the paper matches the bomb, then carry on.

## The device-mix mistake: the call and the bomb on one small screen

The setup that fails most often puts the voice or video call and the bomb on one small screen, usually a phone. The call window covers part of the case, alerts slide over the modules, and the microphone picks up the bomb's own sounds. Give the call a separate device, or at least keep it off the Defuser's screen.

Bomb Appétit has no voice chat of its own, so every group runs a call beside the game. The trap is assuming the call can live anywhere. On a laptop with room to spare, a call window in one corner is fine. On a phone that is also the bomb, the call and the case fight for the same few inches, and the case loses.

The cleanest arrangement gives the Defuser two devices: the bomb on the larger one and the call on a phone with earbuds. Experts can do the same, or keep the call and the manual together on a laptop where both fit side by side. The full set of arrangements, from two screens to a printer to phones only, is compared in [two screens, one screen and a printer, or phones only](/blog/bomb-defusal-game-free-what-you-need#two-screens-one-screen-and-a-printer-or-phones-only).

A related slip is one device trying to show both the bomb and the manual. That breaks the game's central rule, because the Defuser can see the answers, and it shrinks both views at once. Why that setup fails, and what to do instead, is the subject of [the mistake of one device for the bomb and the manual](/blog/bomb-defusal-game-free-what-you-need#the-setup-mistake-one-device-for-the-bomb-and-the-manual).

Before the first round, ask each friend two questions: which device will show the game, and which will carry the call. If anyone answers "the same phone" for both and they are the Defuser, move something. When every seat has a sensible device, open [the Play page](/play), create the room and send the code.
