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

Verdict
The clearest difference is in-app purchases: Mastermind at none against FORMBO's 1. Mastermind also leads on ads (none vs shown) and device support (3 vs 1). FORMBO's advantage is update cadence (daily vs monthly). On price there is nothing between them.
