Mastermind Classic

Mastermind is a code-breaking game for one player. It is based on Mastermind, one of the most popular logic games in history. Its rules are also closely related to the classic game Bulls and Cows, originally played with pencil and paper.

This version features three difficulty levels, so the game can grow with you. You can learn how to play in less than 5 minutes. You are the code breaker, and your goal is to discover the secret combination of 4, 5, or 6 colors. After every attempt, you receive clues that help you improve your next guess:

1. Green Key Peg – one of your pegs has the correct color and is in the correct position.
2. Highlighted key peg – one of your pegs has the correct color, but it is in the wrong position.
3. No Key Peg – the color does not appear in the secret code.
