Based on the classic version of Mastermind, the only real change is that this edition is multi-player, supporting up to 5 players.
In a 5 player game, one person sets the code, and the others take turns making their guesses. Each guess scores points based on its accuracy as follows.
1 point for right color, wrong spot
2 points for right color, right spot
10 points for cracking the code
Game is played over a number of rounds equal to the number of players, most total points wins.
