This is a form of Block dominoes for larger groups of people. It is played with sets of 55 or 91 dominoes.
At the start of each hand the dominoes are divided equally among the players. Any remaining dominoes are left face downward on the table. Play proceeds as for the basic "Block" game except that:
1. the player with the highest double always starts;
2. Any player who plays a double may add another domino if he is able;
3. a player who has placed all his dominoes calls "tiddle wink."
(Another version of the game is played by six to nine players with three dominoes each from a set of 28 dominoes. In this version, dominoes are added to only one side of the starting double and bets are made as in Domino pool.)
