Use your logic skills (and a little bit of luck) to determine the mystery number. The game will tell you how many numbers in your guess are in the mystery number, and how many are correctly in place...but it wont tell you which ones! Thats up to you.
App tracks how many games youve played, how many games youve won, your average number of guesses needed, as well as your best performance!
Youll be addicted before you know it, and it will definitely keep your mind sharp!
