> Of the games to play on Zoom, a bomb defusal round needs no screen share: create a room, send the code, keep cameras on faces and the bomb off the call.
Of all the games to play on Zoom, a bomb defusal round is among the simplest. The host creates an online room in the browser, pastes its five-letter code into the meeting chat, and each player joins from their own tab. Zoom carries only voices and faces. Nobody shares a screen, so the bomb never appears on the call.

## Why games to play on Zoom work better without a screen share

Games to play on Zoom usually lean on screen sharing, and that is where they stall: one person drives, everyone else watches a blurry, delayed picture. A bomb round avoids the problem because each player opens the game in their own browser. Zoom is left to do the one job it does well, which is carrying talk.

In Bomb Appétit the split is the whole point of play. One player, the Defuser, sees a ticking bomb covered in small puzzles called modules. Everyone else is an Expert with the manual and no view of the bomb. The two sides can only win by describing and asking out loud. A shared screen would wreck that, because the Experts could simply look.

Keeping the game off the shared screen also helps the people with weak connections. A Zoom screen share sends a moving picture of someone's desktop to every participant, and on a slow line that picture arrives late or blocky. When each person runs the game locally, a hiccup in the call costs a few words, not the state of the bomb. The Defuser's own browser keeps the timer and the modules running whatever Zoom is doing.

There is a social reason too. With screen share, the meeting view shrinks faces to thumbnails at the edge. Without it, gallery view stays on and everyone can see who is about to speak. In a game built on talking, seeing a face light up before someone says "wait, which wire?" is useful.

The game has no voice chat of its own, so a call app is needed. Zoom fits well when your group already has it open for work or school.

## Setting up the Zoom call and the bomb room side by side

Setting up takes two windows on each computer: the Zoom meeting and a browser tab with the game. The host starts both, creates a room, and puts the five-letter code in the Zoom chat. Players join the room, pick a role, and the host starts the bomb once the Defuser is ready.

Here is the order the host follows. The times are example estimates for a group that has never played, not measured figures.

1. **Open the call** (about 2 minutes). Start the Zoom meeting and wait until everyone can hear each other. Fix microphones now, before any timer is running.
2. **Create a room** (about 30 seconds). In a browser, open [the Play page](/play) and create a room. The page shows a five-letter room code.
3. **Paste the code in chat** (about 30 seconds). Type the code into Zoom's chat panel so nobody has to spell it out by ear. Players open the game and join with the code.
4. **Assign roles** (about 1 minute). Each player picks Defuser or Expert in the room. There is one Defuser per bomb, and the other one to four players are Experts. Agree on the Defuser out loud first so two people do not reach for the same seat.
5. **Start the bomb** (about 10 seconds). The host picks a mission and starts the bomb. The Defuser's screen shows the bomb, and the Experts open the manual.

That is roughly four to five minutes from an empty call to a ticking timer. A group that has played before can do it in two.

### Arranging the windows on each screen

On a laptop, put Zoom on one half of the screen and the browser on the other. The Defuser benefits most from a big browser window, because the bomb has many small parts. Experts can give the manual the larger half and leave Zoom smaller. Someone on a single small screen can keep Zoom on their phone and the game on the computer instead.

Each player also needs a clear idea of which device makes sound into the call. If a laptop joins the meeting and also plays the game's sound effects through its speakers, the microphone may pick them up. Headphones fix that for most people.

## What do Experts on Zoom see while the Defuser plays?

Experts on Zoom see the timer, the strike count and how many modules are solved, and they have the manual. They never see the bomb. Everything they know about the wires, buttons and symbols comes from what the Defuser says over the call, which is why the round works on Zoom at all.

The Expert screen is deliberately thin. For a fuller description of that status line, including the note it gives when a needy module wakes up, read [what an Expert sees in a browser room](/blog/multiplayer-browser-games-to-play-with-friends#what-an-expert-sees-in-a-browser-room). The short version is that the Experts can watch the pressure rise but cannot check the Defuser's work.

On Zoom this creates a particular rhythm. The Defuser speaks most at the start of each module, reading out what is in front of them. The Experts then go quiet while they search, and one of them gives an instruction. A strike shows up on every Expert's status line at once, so nobody needs to announce it. The countdown also speeds up after a strike, which every Expert can see happen.

The manual itself lives in the browser too. The standard manual is [rule seed 1](/manual/1), and the room tells the Experts which manual to open. If two Experts are on the call, they can split the manual's pages so they are not both searching for the same module.

## Which mission works for a first Zoom round?

The first Zoom round should be First bite, the opening mission. It has one module, Wires, and five minutes on the clock, with no needy modules. That gives the group time to learn the talking pattern and fix call problems without a second puzzle piling on.

After that, the missions climb slowly. Button up adds the Big Button to the wires, still with five minutes. Strange symbols brings in the Glyph Keypad for three modules, and its blurb tells the team to agree on names for the symbols. Over a video call, naming matters even more, because nobody can point.

A rough ladder for a Zoom evening, taken from the mission list:

| Round | Mission         | Modules | Time      | Why it suits Zoom                    |
| ----- | --------------- | ------- | --------- | ------------------------------------ |
| 1     | First bite      | 1       | 5 minutes | Learn to describe without pressure   |
| 2     | Button up       | 2       | 5 minutes | One new module, same clock           |
| 3     | Strange symbols | 3       | 5 minutes | Practice naming shapes out loud      |
| 4     | Quick snack     | 4       | 4 minutes | Faster pace once the call is settled |

Section three of the missions introduces needy modules, which wake up mid-round and demand attention. Save those for a later session, once the group is comfortable talking over each other's audio delay. You can see every mission, with its module count and time limit, on [the missions page](/missions).

Swap the Defuser after each round. Everyone should try both seats, and on Zoom the Expert seat is a good place to learn how the call sounds before taking the bomb.

## The Zoom mistake: the Defuser sharing the bomb screen

The most common Zoom mistake is the Defuser pressing Share Screen out of habit. The moment the bomb appears on the call, the Experts stop listening and start looking, and the game turns into a quiz with answers on display. Keep sharing off for the whole round, and keep cameras pointed at faces.

The urge is understandable. Most Zoom activities begin with someone sharing, and new players assume the others need to see. They do not. The game is designed so that the Experts' view is limited, and a shared screen undoes that design from outside the game.

There are quieter versions of the same slip. A Defuser with a webcam pointed down at a laptop shows part of the bomb. A Defuser who holds a phone up to the camera "just to show the symbol" does the same. Both feel helpful and both drain the fun. If a symbol is hard to describe, the fix is to agree on a name for it, such as "the fork with a dot".

A second mistake is the reverse: an Expert sharing the manual. That is less damaging, since the manual is not secret from other Experts, but it makes the Defuser tempted to glance at the call. The manual's own lead says the Defuser should never see it.

If someone does share by accident, stop and restart. A round on Zoom takes a few minutes, and the next one will be better for it.

## Zoom round checklist for the host

A Zoom round checklist keeps the host from fixing problems while the timer runs. Before the bomb starts, the host should know that audio works, the code is in chat, there is exactly one Defuser, and no screen is shared. After the round, the host resets and rotates the Defuser.

Run through it in order:

- Everyone can hear everyone, and nobody has an echo.
- The room code is in Zoom chat, typed, not spoken.
- Every player has joined the room in their own browser.
- One player is the Defuser and the rest are Experts, between one and four of them.
- The Experts have the manual open, with the rule seed the room shows.
- Screen sharing is off.
- Headphones are on for anyone whose laptop speakers play the game sounds.
- The mission is chosen, starting with First bite for a new group.
- After the round, the next person takes the Defuser seat.

Nobody needs an account for any of this. Bomb Appétit is free and runs in the browser, and signing in only adds leaderboards and saved progress. The [how-to-play guide](/how-to-play) covers the rules if a player wants to read ahead before the call.

If your Zoom call is a work meeting rather than a night with friends, the timing changes. Running the game at work on a call, with a set agenda and a thirty-minute slot, is covered in [running a virtual team building round in thirty minutes](/blog/virtual-team-building-games-everyone-talks#running-a-virtual-team-building-round-in-thirty-minutes). For the general case, the post on [virtual team building games that make everyone talk](/blog/virtual-team-building-games-everyone-talks) explains why a bomb round gives every colleague a reason to speak.

Some groups prefer a smaller call app for two or three people. If your friends are on iPhones, the guide to [games to play on FaceTime with friends](/blog/games-to-play-on-facetime-with-friends) sets up the same round with a phone for the call and a laptop for the bomb.
