A version of the code breaking classic Mastermind, it's gameplay is nearly identical to other variants. The player must guess the proper color code by placing pegs into the board (starting at the bottom). The player recieves a white mark for every correct color and a red mark for a correct color in the correct slot. The player must deduce which colors and which slots the pegs belong in before they run out of chances.

This version does allow the player to change the difficulty by adding extra columns. It also has a very clean interface with nice colors.
