Each player tries to fill a 6 x 6 segment of a rainbow game board with colorful plastic tiles. This is achieved by rolling three dice first: Two determine one or two locations (i.e. 1-2 could be read as 12 or 21), the third shows a symbol which determines what happens if a field is already used or whether a player has to discard a tile etc. The first player to fill his/her segment is the winner.
