Codebreaker: Defuse or Boom

Codebreaker: Defuse or Boom is a puzzle game in which you try to crack a secret color sequence set by the Codemaker. Each round, the Codemaker creates a code of four or five Code Lights, with any color combination and repeated colors allowed. You make guesses to match the code’s colors and positions.

Read the hints

After each guess, you receive hints in green, yellow and red. Green means a Code Light has the right color in the right position; yellow means the color is in the code but in the wrong position; red means the color is not in the code. Hints are not given in any particular order, so you must work out which Code Lights they refer to.

Adjust the challenge

Settings let you choose the number of Code Lights and the maximum number of guesses. You can also decide whether correct guesses are revealed immediately, restrict each color to one use, or add a countdown timer. A real-time timer tracks your progress, and monochrome mode is available for players who have trouble distinguishing colors. Sound effects and background music are optional.
