Dominoes, or dominos, is a game played with rectangular "domino" tiles. These gaming pieces constitute a domino set, sometimes referred to as a deck or pack. A standard Sino-European domino set contains 28 dominoes. Muggins, also known as All Fives or Five Up, is a variation of the Draw game. In Muggins, players score points in each move if the sum of the pips at the ends of the line of play is divisible by five, in addition to the end-game scoring. Some variations allow the first double, or all doubles, to act as spinners, creating branching lines of play. In the All Threes variant, players score if the total pip count is divisible by three; in Fives and Threes, scoring occurs if the total is divisible by three or five. SUD Inc.
