If you enjoy finding the solutions using your logic and problem solving skills, then Mastermind Online is the game for you.

Mastermind is a code-breaking game for two players. The objective of Mastermind is to guess the pattern created either by the computer or a human opponent. After you select your color combination from the bottom of the screen, submit your choices. Once submitted, your guess will appear at the top along with small circles to the right of it.

Clear Circle - No colors matched.
White Circle - Correct color, wrong position.
Black Circle - Correct color, right position.

Modify the settings to make the game more challenging for single player.
