Dominoes, or dominos, is a game played using rectangular tiles known as dominoes. These gaming pieces constitute a domino set, sometimes referred to as a deck or pack. A standard Sino-European domino set comprises 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 during each turn if the sum of the pips at the ends of the line of play is divisible by five. Some versions allow the first double, or all doubles, to act as spinners, creating branching lines of play. In the All Threes variant, scoring occurs when the pip sum is divisible by three; in Fives and Threes, scoring happens if the sum is divisible by three or five. SUD Inc.
