After each player gets one chance to bid, the highest bidder chooses the trump for that hand, which can consist of designating as the trump one of the following: a particular "suit" (blanks through sixes, i.e. all tiles containing a six on one or both sides behaves as a trump when played); doubles (any tile containing the same number of pips on each of the two halves of the marked surface of that tile will behave as the trump in that hand when played); or may play with no trump, also known as "follow me".
