Rummoli is a family card game for two to eight people. This Canadian board game, first marketed in 1940 by the Copp Clark Publishing Company of Toronto requires a Rummoli board, a deck of playing cards (52 cards, no jokers), and chips or coins to play. The game is usually played for fun, or for small stakes (e.g. Canadian Dimes). Rummoli is one of the more popular versions of the Stops Group of matching card games, in particular it falls into a subgroup of stops games based on the German Poch and falls into a family of Poch variants such as the French Nain Jaune (Yellow Dwarf), the Victorian Pope Joan but most like the American game Tripoley (a proprietary name, occasionally called by the generic Michigan rummy, but not to be confused with 500 rum) which debuted eight years earlier in Chicago in 1932.

A Rummoli board, used during play, has the shape of an octagon. It is generally simply printed on a large sheet of paper.^{[citation needed]}

In the centre of the board is a pot called Rummoli, surrounded by eight pots:

Each of these pots on the board is used to store chips. The ordering of the pots around the board is not important.

Ace is high. For brevity, in the following description the "lowest card" means the lowest card in a player's hand or, if two or more cards are equally low, either or any of them.

A game is played in one or more rounds. The game ends at the end of a round, at the discretion of the players. For example, it may be agreed to finish at a certain time, or when all but one player have exhausted their chips.

For each round, there are four stages: the Deal, the Poker phase, the Rummoli phase, and the End of round, which are played in sequence.

Before the cards are dealt, each player pays one chip to each pot on the Rummoli board. The dealer then deals around the table to every player, and an extra hand (in some terminology known as a ghost hand) called the widow.
