About

Mastermind

Features
Read full description

Bulls and Cows is a single-player logic game: guess the secret number before time runs out. Digits never repeat. After each guess you get hints. The app uses the Spanish terms Fija and Pica in every language: • Fija (bull): the digit is in the secret number and in the correct position. • Pica (cow): the digit is in the number, but in the wrong position. Choose one of four levels: • Easy: 3 digits, 3 minutes. • Medium: 4 digits, 3 minutes. • Hard: 5 digits, 4 minutes. • Extreme: 6 digits, 5 minutes. There is no attempt limit: you win by cracking the code and lose only when the timer hits zero. Unlock 8 achievements for speed, precision, and difficulty. Progress is stored on your device. The app includes in-game rules, needs no account, and does not connect to our own servers. Free, with no ads and no in-app purchases. Questions? Write to hello@kurubatech.com.
