How many strikes do you get? On 18 of the 20 Bomb Appétit missions the answer is three: the third mistake sets off the bomb. No substitutions, the third mission of Section 4, allows only two. The final mission, also named Bomb Appétit, allows one, so the first wrong move ends the run.
How many strikes each mission allows
Every mission sets a strike limit, and the bomb explodes the moment the strike count reaches it. Eighteen missions use three, No substitutions uses two and the closing mission uses one. The missions page prints the limit on each card, after the clock.
A strike is any mistake on the bomb: a wrong cut, a wrong press, or a needy module left alone until its countdown runs out. The timer also speeds up with each strike, running a quarter faster after the first and half again as fast after the second. Our walk-through of how strikes speed up the clock covers the rates in detail.
| Limit | How many missions | Which missions |
|---|---|---|
| Three | 18 | First bite, Button up, Strange symbols, Table for three, Quick snack, Echo chamber, Word salad, Second helpings, Mixed plate, Rush hour, Signal fire, Spaghetti, Pressure cooker, Full boil, Back of house, Lost in the sauce, The works, Double shift |
| Two | 1 | No substitutions |
| One | 1 | Bomb Appétit |
The limit changes how carefully a team confirms each move before the Defuser acts. The habits below are invented examples of how a team might adapt, not rules from the game.
| Limit | Invented example of the confirm habit |
|---|---|
| Three | The Expert gives the instruction, the Defuser repeats it once, then acts. |
| Two | The Defuser repeats it, and the Expert says "yes, go" before anything is cut or pressed. |
| One | A second Expert reads the same rule independently, both agree aloud, and only then does the Defuser touch the panel. |
The Defuser sees the count as lights on the bomb. What those lights look like and how to read them mid-round is in what the strike lights show.
No substitutions: ten modules on a two-strike limit
No substitutions gives a team ten regular modules, one needy module and ten minutes, and the second strike ends it. One mistake is survivable, but it speeds the clock by a quarter for the rest of the run. After that first strike, the team is playing a one-strike bomb with less time.
The needy module is the quiet danger here. It is drawn from all three needy types, and two of them, Pressure Vent and Dial Alignment, give the team a short countdown to answer when they wake. Missing one costs a strike exactly like a wrong cut does. Name one person to listen for the needy module before the timer starts, so nobody is caught mid-sentence on another page. Our guide to missions with needy modules goes through how to prepare for each one.
With ten regular modules on a case that holds five on its front face, the Defuser also has to turn the bomb over. Reading out both faces before the first cut avoids discovering a module late with the clock already sped up.
Why do the last missions cut the strike limit?
Lower strike limits test accuracy rather than speed. With three strikes a team can learn a page by getting it wrong once. With two, it has to get every module right but one. With one, a single misheard word ends the bomb, so the team is measured on how well it confirms, not how fast it talks.
The final mission adds a second test on top. It uses rule seed 2026 instead of the standard seed 1, so the manual is one the team has never read. Every rule a group remembered from nineteen missions on the standard manual is now worthless, and memory can no longer stand in for checking. The pairing of an unfamiliar manual with a single strike is set out in the one-strike final mission.
Double shift keeps three strikes even though it is the largest bomb, with fourteen modules and three needy ones. Our post on beating Double shift and its fourteen modules covers why volume, not the strike limit, is what makes it hard.
Do strikes count against a defused run on the board?
A defused run with strikes still ranks, as long as the server verifies it. Each mission's board orders players by time left first, so strikes only decide between two runs that end with the same time on the clock. A clean run does not outrank a faster run that took a strike.
Strikes still cost something indirectly. Because each one speeds up the countdown, a run with a strike usually finishes with less time left than the same run would have without it. The result page shows the strike count against the limit, for example "1 / 3", next to the time left. The full ordering, including how the date settles an exact tie, is explained in how a defusal is ranked on the board. You can browse the boards on the leaderboard page.
The strike mistake: guessing because strikes remain
A spare strike is not free time. Every strike speeds the clock for the rest of the round, so a guess that fails costs the seconds it took plus a faster countdown on every module still left. Guessing on the first module of a big bomb is the most expensive guess there is.
The urge to guess usually comes when an Expert cannot find the right line and the Defuser feels the clock. A better move is to say what is unclear, such as the color of one wire, and ask again. If a module is genuinely stuck, the Defuser can leave it and solve another, since modules can be done in any order.
The Defuser's view of the bomb explains what the person holding the bomb can see and touch, which helps an Expert ask questions the Defuser can actually answer.
