> In a game where you defuse a bomb, the Defuser sees the case, the timer, the strike lights and the module panels. What each one means and what to say about it.
In a game where you defuse a bomb, the Defuser is the only player who sees and touches it: the case, the countdown, the strike lights, the edgework on its sides and every module panel. The Defuser's job is to describe all of that clearly, wait for an instruction, say it back and only then act.

## What the Defuser sees on the case

The Defuser sees a bomb case with a countdown, strike lights, a set of module panels and printed details on its sides called edgework. The case has a front and a back, and modules can sit on either. Nothing on it explains itself. Every rule for it lives in the Experts' manual.

Bomb Appétit is a bomb disarm game in which one player holds all of the eyes and none of the instructions. Here is what that player is looking at, piece by piece.

**The timer.** One slot on the case holds the countdown, with the strike lights beside it. The countdown starts at the mission's time limit and runs down to zero.

**Module panels.** Each other slot holds a module, one small puzzle. Every module has a status light. When the module is solved, its light turns green. A regular module stays solved once it is green. A needy module never turns green for good; it sleeps, wakes up, asks for attention and goes back to sleep.

**The back.** Larger bombs carry modules on the back of the case too. The manual tells Experts to ask which modules are on the bomb, front and back, so the Defuser should turn the case over before saying "that's all of them."

**Edgework.** The sides of the case carry four kinds of detail that the manual's rules keep asking about:

- **Serial number.** Six characters. The last one is always a digit. The letters I and O never appear, so a round character is a zero and a straight one is a one.
- **Batteries.** Zero to four battery holders. A holder carries one battery or a pack of two. Rules count batteries, not holders, unless they say holders.
- **Indicators.** A three-letter label beside a light that is either lit or unlit. The label and whether its light is on both matter.
- **Ports.** Sockets for cables. There are six types, and rules care about which types are present.

The manual asks the Experts to collect all of the edgework once, at the start, and write it down. That makes reading it the Defuser's first job. The guide to [reading the serial number out without ambiguity](/blog/bomb-instructions-game-reading-the-edgework#reading-the-serial-number-out-without-ambiguity) covers how to say each item so it is heard correctly the first time.

### Worked example: the first thirty seconds on Button up

Button up is the second mission. It has two modules, Wires and Big Button, a five-minute countdown, three strikes and rule seed 1. The edgework, colors and labels below are example values. Your bomb will show its own.

- **0:00 to 0:05.** The countdown starts at 5:00. The Defuser says: "Started. Two modules on the front: wires and a big button. Checking the back." The case is turned over. "Nothing on the back."
- **0:05 to 0:15.** The Defuser reads the edgework, slowly. Example: "Serial: H, 4, X, E, 9, 2. Last digit two. Batteries: two holders, one with a single battery, one with a pack of two, so three batteries. One indicator, label Y, U, M, light on. Ports: two." The Expert writes each item down and reads the serial back.
- **0:15 to 0:20.** The Defuser picks the wires, the module the team knows from First bite, and describes it: "Wires. Five wires. Top to bottom: white, red, red, black, yellow." (Example values.)
- **0:20 to 0:30.** The Defuser waits. This is the hard part. The Expert is finding the list for five wires and reading it from the top. The rule might depend on the serial number's last digit or on a wire color the Expert needs to double-check. The Defuser's hand stays off the screen until the Expert has finished the sentence and the instruction has been repeated back.

What the Defuser did not do in those thirty seconds matters as much. The big button was not touched. Nobody guessed at a wire. The Defuser described before acting, read the edgework before anyone asked for it and left silence for the Expert to think in.

## How does the timer behave in a game where you defuse a bomb?

In a game where you defuse a bomb, the timer counts down from the mission's time limit and the bomb explodes when it reaches zero. In Bomb Appétit it also speeds up after every strike: 1.25 times normal speed after the first, 1.5 times after the second. The display keeps counting the same way; it simply moves faster.

Time limits vary by mission. The first three missions give five minutes. Quick snack gives four minutes for four modules. The largest bomb, Double shift, gives fifteen minutes for fourteen modules and three needy ones. The countdown on the case starts at whatever the mission sets.

The timer is not just pressure. One module reads it directly. On Big Button, if the Expert says to hold the button, a colored strip lights up beside it. The Expert looks up that color and tells the Defuser a digit. The Defuser keeps holding and lets go when the countdown shows that digit in any position. A Defuser who knows this will read the timer aloud while holding: "Two, fifty-one... two, fifty."

Needy modules carry their own clocks. Pressure Vent and Dial Alignment each wake up with a 40 second countdown of their own, separate from the main timer. When one of them wakes, the Defuser should say so at once, with how much of that small countdown is left.

In an online room, the Experts also see the main timer and the strike count. In the same room they do not, so the Defuser should call out the time now and then, especially after a strike, when the speed-up starts eating into what is left.

## Strike lights: what three of them mean for the Defuser

A strike light records a mistake. Each wrong move on a module, or a needy module left too long, adds a strike and the light beside the countdown shows it. With the default limit of three strikes, the first two speed up the timer and the third sets the bomb off.

For the Defuser, the strike count is a budget. With no strikes, a team can afford one doubtful move. After the first, the clock is running at 1.25 times speed and the margin is thinner. After the second, the clock runs at 1.5 times speed and the next wrong move ends the round.

Not every mission allows three. No substitutions allows two strikes. The final mission, Bomb Appétit, allows one, so its first mistake is also its last. The Defuser should know the limit before the countdown starts, because it changes how careful each move needs to be.

When a strike lands, the Defuser is the only one who sees which module caused it. In the same room, nobody else knows anything happened until the Defuser says so. A useful call is short: "Strike, on the wires. One left." That tells the Experts what failed, how much room is left and that the timer has sped up.

A strike does not always undo the module. Most modules stay as they were and still need solving. A few change when a strike lands; on Color Echo, the mapping between the flashing pads and the right answers changes, so the Expert has to look up the new one. Saying which module struck lets the Expert check whether that applies.

## Touching a module panel: cut, press, hold, turn

The Defuser touches a module in one of four ways: cut a wire, press a key or button, hold a button or lever, or turn a dial or wheel. Each module expects one of these at each step, and the wrong one is a strike. Describe the panel first and let the Expert name the action.

**Cut.** Wires has three to six wires, and exactly one is cut. Tangled Wires and Wire Panels also come down to deciding which wires to cut. Wires are counted from the top, starting at one, so "the second wire" means second from the top.

**Press.** Glyph Keypad has four keys, each with a glyph, and the Expert gives an order to press them in. Passcode has a submit button. Pressure Vent wakes up with a question and a Yes button and a No button. A press on the wrong key or the wrong answer is a strike.

**Hold.** Big Button is either tapped or held. A tap is a press and release in under half a second. A hold keeps the button down until the Expert names the moment to let go. Discharge Lever is held down to drain a meter that fills on its own, and it needs no Expert at all: hold it to drain the meter, let go once it is empty.

**Turn.** Dial Alignment has a turn button that moves the dial one step clockwise, and the dial has to point the right way when its countdown ends. Passcode has five letter wheels with arrows that turn them, and the right word is set before pressing submit.

Before any of these, the Defuser describes what the module looks like. The Expert needs the module's name or appearance to find the right page, and then only the details that page asks about. The guide to [describing a module by shape, then color, then position](/blog/communication-games-describing-a-bomb#the-description-habit-shape-then-color-then-position) gives a habit that works on every panel.

## 2D or 3D bomb view: which should the Defuser pick?

The Defuser can play Bomb Appétit with the bomb in 3D or in 2D. Both views show the same bomb, the same modules and the same timer, and a run plays out the same in either. The game's own advice is to pick whichever your device likes better, so the choice comes down to the screen.

On a laptop or a tablet with room to spare, the 3D view is worth trying first. It presents the case as an object with a front, a back and sides, which matches how the manual talks about modules and edgework.

On a phone, or on an older computer where the 3D view feels slow, the 2D view is the practical pick. A Defuser who is squinting or waiting for the screen to respond describes worse, and that costs the team more than any view could save.

Bigger screens help in either view. The bomb is easiest to handle on the largest screen available, and the manual reads well on anything. If the household has one laptop and one phone, the bomb belongs on the laptop.

The view is a Defuser's comfort setting, not a strategy. Pick it before the first round, and change it between rounds rather than in the middle of a countdown.

## The Defuser's mistake: acting before the Expert finishes the sentence

The Defuser's classic mistake is acting halfway through an instruction. Manual rules often have two parts, a condition and an action, and the action can come last. A Defuser who hears "cut the third wire" and cuts may miss the "unless" that followed. Wait for the full sentence, say it back, then act.

Look at how the manual phrases things. A wires rule reads like "If there is exactly one red wire and the last digit of the serial number is odd, cut the third wire." An Expert reading aloud may start with the action, correct themselves, and then add the condition. A hand already on the wire turns that correction into a strike.

Big Button makes the cost obvious. "Hold the button" and "tap the button" begin the same way. A Defuser who presses on hearing "button" has already committed to either a tap or a hold, and only one of them is right for this bomb.

The repeat-back is the fix, and it is cheap. The Expert gives one instruction. The Defuser says it back in full: "Holding the button. Waiting for the strip color." The Expert confirms. Then the hand moves. It costs a couple of seconds and saves whole rounds.

The same patience applies to needy modules, where the countdown makes waiting feel risky. A Pressure Vent question gets read out word for word, the Expert finds it and says the answer, and the Defuser presses Yes or No only after hearing it. A wrong press is a strike just like a timeout.

Playing as a pair makes this habit easier to build, because there is only one voice to listen to. The guide to [a two-player game with one Expert](/blog/2-player-bomb-defuse-game-one-expert) covers pacing for that setup.

Every rule mentioned here is also on the [how to play page](/how-to-play), and the [standard manual](/manual/1) shows what the Experts are reading while you wait.
