Classic Mastermind is a game of logic and ingenuity that consists of guessing a secret code made up of a sequence of colors. Developed by RC4812, this free Android game offers two game modes: Classic and Initiation, along with six different types of games. The Classic mode is the traditional game mode, whereas the Initiation mode is for players without experience.

Classic Mastermind has a simple and intuitive layout, with five columns that show the records, numerical sequence, clues, rows to place colors, and colors in play. Players can play with colors, numbers, or emoticons (smileys) and place them in the desired position of the row in play by either dragging and dropping or pressing the desired color and then pressing the destination position.

The game ends by hitting the code or completing the last row, and the clues indicate whether the color has been placed in the correct or wrong position. Classic Mastermind also offers various options, including autocomplete, repeated colors, and extra color. The game's auto-save/load feature allows players to pick up where they left off in their previous session. Overall, Classic Mastermind is a fun and challenging game that will test your logical thinking and reasoning skills.
