Mondoes is a rummy-like set collection game. The 112 card set is made up of 4 suits each with two numbers. The object of the game is to earn points by playing pairs of cards that score points by matching suit and matching numbers. (Matching numbers can be identical or sequential) Players draw and discard until one player thinks they have a high enough score and calls "Mondoes". Other players can challenge the call if they believe they have a higher hand. The game ends when one player has obtained 250 points.
