4A

4A is a compact logic puzzle game that challenges players to deduce a secret four-digit number using just two types of feedback. Each turn you submit a guess and receive 'A' clues for digits that are correct and in the right position, and 'B' clues for digits that are correct but in the wrong position. That clear mechanic creates quick, brain-teasing rounds where pattern recognition and strategic elimination matter. Players can sharpen deduction skills, compete to outguess an opponent, and enjoy short, satisfying matches that end when the target number is revealed as 4A.
