Bulls and Cows is a code-breaking logic game, similar to Mastermind. But in this game 4-digit numbers are used instead of color combinations. Try to guess a random number within twelve attempts. You’ll get hints as to how many digits and how many positions you got right.

Features:

– try/time scoring
– sound effects
– high score tracking
