You set the secret code. You start the countdown. Then you hand over the phone.
Your friend has to break that code before the timer reaches zero.
Every confirmed entry tells them how close they are. Nothing else.
HOW IT WORKS
1. Set the code. Pick a length from 2 to 6 digits and choose how long the round runs.
2. Hand over the phone. The defuser starts with nothing but empty slots and a keypad.
3. Read the feedback. Each confirmed entry shows how many digits are correct and how many sit in the wrong position. Bulls and cows logic, played against a clock. Deduce the rest before the timer dies.
MATCH: TWO PLAYERS, ONE PHONE
Play a series of rounds and swap roles. One of you plants the code, the other defuses it. Set the match to anything from one win to nine, and a tied score goes to overtime. The phone travels back and forth across the table, and so does the pressure. No second device, no account, no internet.
CAMPAIGN: 12 MISSIONS
Twelve missions, each harder than the last, each with its own briefing and its own gear artwork. Clear a mission for silver. Clear it with hints switched off for gold. Best times are kept, and the last missions do not forgive slow hands. No second player needed — the campaign is a game for one.
QUICK GAME: START IN ONE TAP
No setup, no partner. The app writes a random code and starts the clock. Open it on a break, play a full round, put the phone down. It is the fastest way to learn how to read the feedback, and the honest way to find out how many digits you can hold in your head.
BUILT FOR AIRSOFT, PAINTBALL AND PARTIES
Airsoft players already carry it instead of a home-made prop: set the code, set the timer, put the phone on the objective, and the other team has exactly as long as you gave them. The same works at paintball games, escape-room evenings, birthdays, and with kids who want a countdown they can actually beat. Rounds run with no internet, so woods and basements are not a problem.
Use it in organised games only, and do not leave a phone running a countdown in a public place.
MAKE THE BOMB YOURS
Five themes are free from the start: base, classic, military, cosmonaut, calm. After that the bomb comes apart into layers — background, body, panel and buttons — and each one changes on its own: taped bundle, pipe cluster, bare board, ammo crate, copper vessel, dive housing. Real textures, not flat fills. Every theme ends its round its own way, whether the code falls or the clock wins.
Premium skins are free to try: one premium round a day, plus another for watching a video. Clear all twelve missions on gold to unlock the button styles for good.
TUNE THE DIFFICULTY
Code length from 2 to 6 digits. Rounds from 30 seconds to half an hour. Hints on when you are teaching someone, off when you want the real thing. Sound and haptics on separate switches, because a bomb buzzing in your pocket is either the whole point or a problem.
Set a code. Hand over the phone. Find out how your friends think when the clock is running.
One sets the code, one cracks it! Two players, solo campaign, airsoft.
