Keep Talking and Nobody Explodes: Complete Guide

This covers both roles in Keep Talking and Nobody Explodes: the Defuser, who has the bomb, and the Experts, who have the manual. It walks through how to read a bomb, how each vanilla module works, communication habits that actually save time, and how to get into mods.

Researched September 2026, current as of patch 1.9.31 (August 2026, which added Steam Frame VR support). Live games change; check the linked sources if something differs.

Quick Start

• Only the Defuser needs the game. The Experts use the free Bomb Defusal Manual at bombmanual.com, either printed or on a screen. Nobody on the Expert side should ever see the bomb.
• Use the right manual version. The current English manual is Version 1 (verification code 241). Translated manuals have their own version numbers, and an out-of-date translation will give wrong answers on some modules.
• Read the edgework before touching anything. The serial number, battery count, lit indicators and ports decide the answers on several modules. The Defuser should read them out at the start of every bomb.
• Three strikes and it explodes on standard bombs, and each strike makes the timer run faster. A strike costs you more than the one mistake.
• Split the manual among the Experts. With two or more Experts, give each person a few modules to own, so nobody has to flip through the whole manual.
• Describe what you see, not what you think it means. "Four wires: red, white, blue, blue, from top" is better than "I think it's the blue one."
• Needy modules never finish. Venting Gas, Capacitor Discharge and Knobs keep coming back until the bomb is solved. Keep an eye on their timers between other modules.
• Play the missions in order. Each section of the binder brings in new modules at a manageable pace, and Free Play unlocks as you go.

The Two Roles

Role | Has | Job

Defuser | The game (keyboard/mouse, controller or VR) | Describes the bomb clearly, carries out instructions, keeps an eye on the timer and needy modules

Expert(s) | The Bomb Defusal Manual | Finds the right rule quickly, asks clarifying questions, gives one unambiguous instruction at a time

For remote play you can use any voice chat app (Steam, Discord, Zoom). The developers point to this for playing with people in other countries.

Reading the Bomb (Edgework)

Turn the bomb over and look at its sides and bottom before you start any module. Say all of this out loud:

• Serial number: read it character by character. The Experts should write it down. Rules often depend on whether the last digit is odd or even and whether the serial contains a vowel.
• Batteries: count them. The manual's appendix shows the AA and D battery types. Rules count batteries, not battery holders.
• Indicators: a small light with a three-letter label, either lit or unlit. The appendix lists the possible labels: SND, CLR, CAR, IND, FRQ, SIG, NSA, MSA, TRN, BOB, FRK. Always say whether it is lit.
• Ports: DVI-D, Parallel, PS/2, RJ-45, Serial, Stereo RCA. The Parallel port matters for Complicated Wires.

A good habit is for the lead Expert to repeat the edgework back as a summary, e.g. "Serial ends in 4, has a vowel, two batteries, lit FRK, parallel port." That settles it for the rest of the round.

Vanilla Modules

The base game has 11 regular modules and 3 needy modules. Here's what each one asks of both roles.

Regular modules

Module | Defuser describes | Expert needs to know | Notes

Wires | Number of wires and each color, top to bottom | Serial last digit for some cases | Rules branch on 3, 4, 5 or 6 wires

The Button | Button color and label | Batteries, lit CAR/FRK | May need holding; the strip color gives a release digit

Keypad | The four symbols | Symbol columns in the manual | Press in the column's top-to-bottom order

Simon Says | Each flash in sequence | Vowel in serial, current strike count | The mapping changes after a strike

Who's on First | Display word, then button labels | Two lookup tables | Hardest to communicate; spell out tricky words

Memory | Display number and the four labels each stage | Previous stages' positions and labels | A wrong press resets to stage 1

Morse Code | Dots and dashes of the blinking light | Morse chart and the word list | Answer is a frequency, e.g. "shell" is 3.505 MHz

Complicated Wires | For each wire: red? blue? star? LED on? | Venn diagram, serial, batteries, Parallel port | Letters C, D, S, P, B

Wire Sequences | Wire color and letter it connects to, per panel | Running count of each color | Expert keeps the count across panels

Mazes | Location of the two green circles, white light, red triangle | Which of the mazes matches | Walls are invisible to the Defuser

Passwords | Available letters in each column | 35-word list | Narrow down with the first letter or two

Module-by-module tips

Wires. Count the wires first, because each count has its own rule list. For 3 wires: if there are no red wires, cut the second wire. Otherwise, if the last wire is white, cut the last wire. Otherwise, if there is more than one blue wire, cut the last blue wire. Otherwise, cut the last wire. Always count positions from the top and ignore empty slots.

The Button. The Expert works down the rules in order and stops at the first one that matches. If the answer is "hold," the Defuser holds the button and reads out the color of the lit strip beside it. Blue means release when the timer has a 4 in any position, yellow means 5, white or any other color means 1.

Keypad. Only one column in the manual contains all four symbols. Settle on names for the symbols as a group and reuse them ("copyright," "backwards C," "tennis racket") so you don't have to argue about them every round.

Simon Says. The Defuser reports only the newest flash each round; the Expert keeps the full sequence. After any strike, the Expert must switch to the next column of the table, which is where many teams mess up.

Who's on First. The display may show words like "YOU," "YOU'RE," "UR," "THEIR," "THERE," "BLANK," or be completely empty. Always spell out the ambiguous ones letter by letter. The module has three stages.

Memory. The Expert has to write down the position and label pressed at every stage, because later stages refer back to both. A wrong press resets the whole module to stage 1.

Morse Code. The light loops with a longer gap between repetitions. Wait for that gap, then read the full word. You usually only need the first three or four letters to pick a unique word from the list.

Complicated Wires. Report each wire as four yes/no answers: red, blue, star, LED. The Venn diagram returns one letter: C cut, D don't cut, S cut if the serial's last digit is even, P cut if there's a Parallel port, B cut if there are two or more batteries.

Wire Sequences. Multiple panels, each with up to three wires. The Expert keeps a tally of red, blue and black wires seen so far, since the rule for each wire depends on how many of that color have already appeared.

Mazes. The Defuser says where the two circle markers are, using a coordinate system you agree on beforehand (column then row, 1 to 6, from top-left). The Expert picks the matching maze and gives moves one step at a time.

Passwords. Each of the five letter slots cycles through a few letters. Read the full set for the first column, then the second, and the Expert can usually eliminate everything but one word quickly.

Needy modules

Needy module | What to do

Venting Gas | Answer the on-screen Y/N prompt as the manual says

Capacitor Discharge | Hold the lever down to drain it before its timer runs out

Knobs | Match the pattern of lit LEDs to the manual's table and turn the knob to Up/Down/Left/Right

These can't be disarmed. They reactivate throughout the round, so the Defuser should glance at their timers after every regular module.

Communication System That Works

• Agree on a coordinate system before the first bomb (rows and columns from top-left).
• Use "check" or "confirmed" loops. The Expert repeats the key facts, the Defuser confirms, then acts.
• One instruction at a time. "Cut the third wire," then wait for "done."
• Defuser announces strikes immediately, because Simon Says and some other rules depend on the strike count.
• Name the module first. "New module: Complicated Wires, 5 wires." This tells the right Expert to take over.
• Call out the timer at intervals when it's getting low, so Experts know when to guess.
• Don't argue while the clock runs. If there's a disagreement, the person who owns that module decides.

Game Modes

Mode | What it is

Missions (the binder) | Curated bombs grouped into sections that introduce new modules gradually

Free Play | Build your own bomb: set the timer, module count, whether needy modules appear, and a harder no-strike option

Mods / Workshop | Community modules and missions loaded through the in-game Mod Manager

VR: In VR the Defuser feels more cut off from the Experts, which is part of the appeal. Patch 1.9.31 (August 2026) added Steam Frame support to the Windows version. Swapping Defusers between rounds works well at parties.

Languages and Translated Manuals

Official Steam translations cover 26 languages, including Arabic, both Chinese variants, Czech, Dutch, French, German, Hebrew, Japanese, Korean, Polish, both Portuguese variants, Russian, Spanish, Thai, Turkish and Ukrainian. Each language needs its own manual version, found at bombmanual.com under the language code (e.g. bombmanual.com/ru). Some translations were revised later. The Russian manual moved to version 2-ru with new Keypad symbols, for example, and older copies no longer match the game. If you play in another language, check the version shown on the manual against the game's.

Mods and the Community Repository

The Steam Workshop has a large library of community modules, missions and tweaks. The community keeps the manual pages for modded modules at the Repository of Manual Pages (ktane.timwi.de). Tips:

• Download the manual page for every mod module you enable, and send it to your Experts before starting.
• Add mods a few at a time. Hundreds of modules at once makes for miserable bombs.
• If mission mods stop loading after an update, disable them all and add them back one by one. Patch 1.9.24 fixed a regression involving multiple mission mods, so keep the game updated.

Common Mistakes to Avoid

• Skipping edgework. Most wrong cuts on Wires and Complicated Wires come from a battery count or serial digit nobody checked.
• Saying "lit" when you mean "there is an indicator." Unlit indicators don't count for rules that ask for lit ones.
• Counting wire positions including empty slots. Count only wires that are present.
• Forgetting strikes change Simon Says. Once there's a strike, the old mapping is wrong.
• Pressing Memory buttons before the Expert has recorded the stage. A mistake here costs you the whole module, not just one step.
• Letting needy modules time out while the whole team is focused on a hard regular module.
• Using a mismatched translated manual. Keep the game language and manual version the same.

Advanced Tips

• Preload knowledge between rounds. Experienced Experts memorize the short ones (3-wire rules, Button strip colors, Complicated Wires letters) so they can answer instantly.
• Parallelize with two Experts. One reads needy modules and edgework while the other works the main module.
• Build a shorthand vocabulary for Keypad symbols and Who's on First words, and write it on the manual's margin.
• Solve easy modules first on a crowded bomb. Wires, Button and Passwords buy you time and calm.
• On Morse, write it down as dots and dashes before decoding. Don't try to decode live.
• Practice in Free Play with a long timer and one new module type to learn its flow before facing it in a mission.
• For speed runs, have the Defuser read Wire Sequences panels and Mazes in a fixed format every time so the Expert's ears know what to expect.

FAQ

Does everyone need to buy the game? No. Only the Defuser needs a copy. Experts use the free manual at bombmanual.com.

Can we play online with friends in other places? Yes. There's no built-in online mode, but the Defuser can play while everyone talks over Discord, Steam or Zoom. The Experts just open the web manual.

Why did we get a strike when we followed the manual exactly? Usually it's a manual version mismatch (especially for translated manuals), missed edgework, or a Simon Says strike-count error. Check that the manual's verification code matches your version.

Can the Defuser look at the manual? The game is designed so they don't. Peeking removes the communication challenge that makes it fun.

Is there a mode with no strikes allowed? Free Play lets you configure a harder setup, and many Workshop missions are built around tougher rules.

Does it work on Steam Deck or VR? The Windows version supports VR headsets, and patch 1.9.31 added Steam Frame support. For Steam Deck compatibility, check the current rating on the Steam store page.

How many modules are in the base game? Eleven regular modules plus three needy modules. Workshop mods add many more.
