The most commonly played domino games are Domino Whist, Matador, and Muggins (All Fives). Other popular forms include Texas 42, Chicken Foot, Concentration, Double Fives, and Mexican Train.
They were played first in Italy and France and later in England and then the New World. Dominoes are frequently called bones, because the earliest dominoes were made from animal bone or ivory.
American Mah Jongg is considered the most difficult style because only the hands listed on a card are considered valid. This requires players to memorize the card (or at least have a good grasp of it).
