Double-six draw rules
Match.
Draw. Pass.
The 28 unique double-six tiles are shuffled and seven are dealt to each player. The highest double in either hand opens; if neither hand has a double, the highest pip total opens. The other player takes the next turn.
Play one tile matching either open end. If you have no legal tile, draw one tile at a time until you can play or the boneyard is empty. Only then may you pass. Empty your hand to win. If both players pass consecutively, the round is blocked and the lower remaining pip total wins; equal totals draw.
