Multiplayer Pebbles is an arcade 2D game for Mac OS. Your goal in this game is to reveal a secret code formed by at most 4 color pebbles before your opponent does so. When the game starts, you and your opponent will be asked to form a secret code for each other to guess. Spaces are allowed in the code and the colors of the pebbles may repeat. Then you will be given an empty board, and 8 pebbles of different colors will be placed on the panel on the left of the board.
