Abstract

An automatic card shuffling machine including a dealing module and a display module. The machine has a microprocessor and a deck-receiving shuffling station into which a deck of cards is deposited initially. A carriage mechanism separates the deck into two deck portions, rotates the two portions to a relative angular relationship with a corner of each in close proximity, riffles the portions, and combines them into a single shuffled deck. A shuffled deck delivery system delivers the shuffled deck to the dealing module which moves a predetermined number of cards, one at a time, into a hand holding shoe. The display module displays game information to players. The machine is particularly well-suited for playing pai gow poker.
