概要
Code Breaker (Mastermind) is a code-breaking game of logic and deduction. One player creates a secret code using colored pegs, and the other player attempts to guess it within a limited number of tries, receiving feedback after each guess.
歴史
Mastermind was invented in 1970 by Mordecai Meirowitz, based on an earlier pencil-and-paper game called Bulls and Cows. It has sold over 50 million copies worldwide.

戦略
Start with a guess using 4 different colors to maximize information.
Track your guesses and feedback carefully
Elimination is key.
If you get black pegs, keep those positions and test other colors.
White pegs are valuable
You have the right colors, just wrong positions.
A good second strategy
Change one color at a time to isolate information.
As codemaker
Use duplicate colors to increase difficulty.
バリエーション
Mini
4 colors, 3 pegs (easier, good for children).
Super
8 colors, 5 pegs (much harder).
Numbers
Use digits 1-6 instead of colors (good for digital versions).
No duplicates
Easier variant where each color appears only once in the code.
