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: โ€ข Fija (bull): the digit is in the secret number and in the correct position. โ€ข Pica (cow): the digit is in the number, but in the wrong position. Choose one of four levels: โ€ข Easy: 3 digits, 3 minutes. โ€ข Medium: 4 digits, 3 minutes. โ€ข Hard: 5 digits, 4 minutes. โ€ข 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.
