Code Breaker: Bulls & Cows

Crack the secret code! Code Breaker is the classic logic game of colors and numbers, rebuilt with gorgeous gem graphics, a smart AI opponent and helpers that teach you to think like a real codebreaker.

A secret code is locked in the vault. Make a guess and read the answer: a gold peg means a right piece in the right place, a silver peg means a right piece in the wrong place. Use pure logic to find the code before you run out of rows.

TWO CLASSIC GAMES IN ONE
💎 Colors: crack a code of sparkling gems, 4 to 6 pegs and 6 to 8 colors
