Players each draw a set of pieces, or bones. Each end of the bone features dots from 1-6 or a blank. Players take it in turn to put down a bone which matches the number on a bone already played.
If you cannot match a number in play you pick up new bones until you can.
The winner of the round is the first player to get rid of all their bones. The loser adds all the dots on their bones together. This is their score. The player with the lowest score at the end of the match is the winner.
