Dominoes, or dominos, is a game played using rectangular tiles known as dominoes. These gaming pieces comprise a domino set, sometimes referred to as a deck or pack. A standard Sino-European domino set contains 28 dominoes.
Muggins, also called All Fives or Five Up, is a variation of the Draw game. In addition to end-game scoring, players score points on each turn if the sum of the pips at the ends of the line of play 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 sum is divisible by three; in Fives and Threes, they score if it's divisible by three or five. SUD Inc.
