Code Breaker is an Android game that challenges players to break a secret code by placing colored pegs in a row. The game is similar to the classic Mastermind game and features different levels of difficulty, including easy, medium, hard, and extreme modes. Players can also customize their gameplay experience by selecting different shapes, letters, numbers, or pegs, and can even set the code for each other, making it a two or more player game.

In addition to its customizable gameplay, Code Breaker offers various settings, including the ability to turn sounds on or off, set empty holes, repeat colors, enter code, and more. The game is automatically saved to the device, allowing players to resume their game even after restarting the app. With four different backgrounds to choose from and simple sound effects when pegs, holes, and buttons are pressed, Code Breaker is a fun and engaging game that offers a classic challenge for players of all ages.
