The card game is played using two decks of cards per each hand, with the dealer
dealing out two groups of cards face down from one deck and a single face up reference
card from the second deck. The dealer then turns up each of the cards sequentially
from the two groups of the first deck, with the object being to attain an exact
match between any or the cards of the two groups, and the reference card. Optionally,
players may wager upon the likelihood of the occurrence of a specific mismatch.
