Dominoes All Threes

Scoring swings on the exposed pip total. In a match of Dominoes All Threes, points land the moment the layout adds up to a multiple of three, then round bonuses go to the hand winner. Any tile may hit the table first. A double placed as the spinner sends play out from four sides. Its exposed ends all add into the total until two tiles attach to that double, after which the double's number drops out of the count. Several rounds stack together, and the first score above 100 takes the match.

How to play?

Place a tile against a matching end and score right away when the exposed pip total lands on a multiple of three. Boneyard draws continue until a playable piece appears or the pile runs dry. Passing happens when no legal tile remains, and no draw is available. Emptying your hand ends the round with a win. Blocked play also ends the round, with victory going to the lower hand total.
