Dominoes is the tile game that predates almost everything else in this catalogue: a set of 28 tiles, each with two numbered ends, played end-to-end so that touching ends match. This version offers the three modes people actually play — Draw, where you take from the boneyard when stuck; Block, where you simply pass; and All Fives, where open ends totalling a multiple of five score points.
It is a game of counting rather than luck. Track which numbers have been played and you can work out what your opponent is holding, then leave an end they cannot match. That is the whole skill, and it is why dominoes has survived for centuries.
In Draw dominoes, a player who cannot move takes tiles from the boneyard until they can. In Block dominoes there is no drawing — you simply pass, which makes counting the played numbers far more important.
You score each time the numbers on the open ends of the chain add up to a multiple of five. Doubles count both their halves, so a double-five at the end contributes ten.
