28 tiles, from 0-0 to 6-6. Each player is dealt 7 tiles. With 2 players the 14 left over form the boneyard.
Whoever holds the highest double opens with it. No doubles? The highest tile opens.
Draw: you must draw when you cannot play; you pass only when the boneyard is empty. Block: no drawing, you pass.
Empty your hand first and you score all the pips left in your opponents' hands. If the game is blocked (everyone passes in a row) the lowest pip total wins and scores the difference. A tie scores nothing.
You and the player opposite you are a team. Your team's pips are added together and scores are shared.
Reach the target score (100, 150 or 200) first.
One hard match a day with the same deal for everyone. Play on back-to-back days to build your streak (one missed day is forgiven).
You get 3 hints per game. A hint shows the move the computer would make.
