About Gem Master

A very challenging code breaker game based on the classic Mastermind.

The classic code-breaking game with a twist, making this the most challenging Mastermind clone ever! The object of the game is to solve the hidden code using a series of guesses and deduction based on the clues given after your guess is scored. But watch out for traps that try to fool you. Also, this game uses a timer. Run out of time, and you lose. Because this game is so challenging, wild gems (which match any gem in the hidden code) are available to help you when you need it most.
