Pitty Pat
Pitty Pat is the national card game of Belize. It is played by from two to four players with a standard 52 card pack. Though it may not be apparent at first sight, Pitty Pat is essentially a rummy game with a similar mechanism to conquian, in which the objective is to make three pairs starting from a five card hand. Details can be found on the Pitty Pat page of the Belizeans.com web site.
A Pitty Pat computer program is available from Unique Games.
