Dominoes, or dominos, is a game played using rectangular tiles. A domino set, sometimes called a deck or pack, comprises these gaming pieces. The 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 not only at the game's end but also on each turn if the sum of the pips at the ends of the domino line is divisible by five. 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, they score if it's divisible by three or five. SUD Inc.
