> How long does a bomb defusal game take? A round lasts four to fifteen minutes on the clock, plus setup. Times for every mission section and a first-hour plan.
How long does a bomb defusal game take? It depends on the mission. In Bomb Appétit, the clock runs from four to fifteen minutes, and a round stops sooner when the bomb is defused or explodes. Add two or three minutes of setup before the first round, and about a minute before each one after it.

## How long does a bomb defusal round last on the clock?

A bomb defusal round lasts at most as long as its time limit, which ranges from four minutes on the quickest early missions to fifteen on the biggest bomb. Most of the twenty missions sit between five and seven minutes. Freeplay bombs can be set anywhere from one minute to sixty.

The time limit is a ceiling, not a target. A round ends the moment the last regular module turns green, so a confident team on a small bomb often finishes with minutes to spare. It also ends if the clock reaches zero or the team runs out of strikes.

The missions are grouped into four sections, and the clocks grow with the bombs. The table below shows the shortest and longest time limit in each section. The last column is our own estimate of a typical round from sitting down to the result, including a minute or two of setup and a quick reset, for a group that has played once before. It is an example for planning, not a measurement.

| Section | Missions                          | Shortest time limit | Longest time limit | Typical round with setup (estimate) |
| ------- | --------------------------------- | ------------------- | ------------------ | ----------------------------------- |
| 1       | First bite to Quick snack         | 4:00                | 5:00               | 5 to 7 minutes                      |
| 2       | Echo chamber to Rush hour         | 5:00                | 7:00               | 6 to 9 minutes                      |
| 3       | Signal fire to Back of house      | 6:00                | 9:00               | 8 to 11 minutes                     |
| 4       | Lost in the sauce to Bomb Appétit | 6:00                | 15:00              | 8 to 17 minutes                     |

Section 4 has the widest spread. Lost in the sauce runs on a six-minute clock, while Double shift, the largest bomb in the game, has fifteen minutes for fourteen modules and three needy ones. The [missions page](/missions) lists every clock if you want to plan around one bomb in particular.

In freeplay, the setup screen suggests five minutes for three modules and adds a minute for each extra module, which is a sensible default when you build your own bomb.

## Setup time before a bomb defusal game: the minutes nobody counts

Setup before the first round usually takes two to five minutes, and it is the part people forget when they plan. Someone opens the bomb, someone opens the manual, the screens get turned, and everyone checks the rule seed. Later rounds reuse all of that, so they start in about a minute.

Here is what the first setup involves, in order:

1. The Defuser opens [Play](/play) and picks a mission.
2. Each Expert opens the manual on a device or picks up a printed copy.
3. The group checks that the manual's rule seed matches the bomb's.
4. The bomb screen is turned away from the Experts, or everyone joins the online room with its five-letter code and a call.

Online setup tends to take longer than same-room setup, mostly because of the call. Getting everyone onto one call, with working microphones, often costs more time than the game itself asks for. The game has no voice chat of its own, so that step is always separate.

Seating matters too. A sofa layout, with the bomb on a TV or laptop and the Experts out of view, takes a minute of shuffling the first time. The guide to [couch co-op with one bomb on one sofa](/blog/couch-co-op-games-one-bomb-one-sofa) covers where everyone sits so the shuffle happens once.

## How many bomb rounds fit in an hour?

A new group fits five to seven rounds in a first hour if it stays in the first section and keeps the talk between rounds short. Each early round is four or five minutes on the clock, with setup and a quick chat about what went wrong around it. Bigger bombs later in the evening fit fewer per hour.

The plan below is an example for three or four people who have never played. The times are our estimates, not rules from the game.

- **0:00 to 0:05.** Setup: devices, manual, seed check, seating.
- **0:05 to 0:12.** First bite, one module. Talk about how the description went.
- **0:12 to 0:20.** Button up, two modules. Swap the Defuser.
- **0:20 to 0:28.** Strange symbols, three modules. Agree names for odd symbols afterwards.
- **0:28 to 0:36.** Table for three. Swap the Defuser again.
- **0:36 to 0:44.** Quick snack, four modules on four minutes.
- **0:44 to 0:60.** A repeat of whichever mission exploded, or the first mission of section two.

That shape leaves room for a failed round or two, which a first hour almost always has. For an evening longer than an hour, the section on [how long a bomb game night should run](/blog/how-to-host-a-game-night-browser-bomb#how-long-should-a-bomb-game-night-run) covers pacing and when to stop.

## When a bomb round ends early: strikes and short clocks

A round ends early in two ways: the team defuses the bomb before the clock runs out, or it collects one strike too many. A run of quick mistakes can finish a five-minute bomb in under two minutes. Strikes also speed up the clock, so time left drains faster after each one.

The speed-up is easy to underestimate. After the first strike, the countdown runs at 1.25 times its normal speed. After the second, it runs at 1.5 times. Take an invented example: a team with three minutes left takes a second strike. At one and a half times speed, those three minutes on the display last only two minutes of real time.

Strike limits change the picture as well. Most missions allow three, but No substitutions allows two and the final mission allows just one. On a one-strike bomb, a single wrong cut ends the round instantly, however much time is left.

Short rounds are not wasted rounds. A bomb that blew up in ninety seconds usually points to one clear problem, such as a mismatched seed or a misheard colour. Fix it and go again.
