Dominoes Big is a full implementation of the classic game with the traditional opening: the player holding the highest double starts, which is double-six if anyone has it. Hands are seven tiles for two players and six for more.
It supports multiple players, so it works as a proper game of dominoes rather than a simplified one.
The player holding the highest double — double-six if it's in play, otherwise the next highest. If nobody holds a double, the highest tile starts.
Seven each in a two-player game, six each with three or four players, from the standard 28-tile double-six set.
Yes — tap to place tiles. Nothing to install.
