MasterMind by MinionSoft is a board game made for PICO-8.
It is a code-breaking game. Your goal in the game is to guess the 4 color code laid out by the author. You have a few tries to guess the code. If you fail to do so, you won’t earn any points and fail the game. There’s a timer on the side screen as well, if you guess it right in a few minutes your name will be placed in the positions category.
