Classic Mastermind is an Android game developed by RC4812 in the board game subcategory. It is a traditional game of logic, ingenuity, and reflection where the player has to guess a secret code made up of a sequence of colors. The game offers two modes: code maker and code breaker.

In code maker mode, the application generates the secret code automatically for a single player, while in two-player mode, one of the players places the secret code. The code breaker mode requires the player to guess the secret code. The game layout consists of five columns with rows where the colors must be placed to guess the code. The clues appear after confirmation of the combination of each row.

The game offers four types of game modes, namely Nano3, Mini4, Super5, and Mega6, with different levels of difficulty. The game also allows the player to set the options of playing with colors, shapes, numbers, or letters, with repeated colors, an extra color, an empty gap, sound, and flash. The game records the minor row where the game has been solved, and each combination of game type, level, and options has a different record.
