The game and number of players change from the next game.
A set of 28 tiles, each with two ends showing 0 to 6 pips. Everyone gets a hand of tiles; the rest face down make the pile. Empty your hand first to win the hand. The first player to 100 points wins the game.
Add one tile to either open end of the line. The touching ends must show the same number. Tiles you can play are lifted; tap one to play it. If it fits both ends, tap the end you want.
Can't play? In the Draw game, draw from the pile until you can (with the pile empty, pass). In the Block game there is no drawing: you pass.
Two players get 7 tiles each. In the Draw game with three or four players it's 5 each; the Block game always deals 7. The first hand starts with the highest double, played by whoever holds it. After that, the winner of the last hand starts with any tile.
Whoever empties their hand scores the pips left in everyone else's hands. If nobody can play, the hand is blocked: the lowest pip count wins it and scores the others' pips (a tie scores nothing).
Tap ⋯ → Play friends online and send the link to 1–3 friends. Each of you sees only your own tiles; online games are the Draw game to 100.
