Mastermind Online is an iconic puzzle game. This is the online version. Players must guess the combination of four colored pins and put them in the right sequence before they run out of turns. The game will provide the player with hints to indicate whether the pins they have chosen are the right color or whether they are placed in the right position. The objective is to crack the code within 10 attempts.
