DECiMiX is a game where the aim is to be the player scoring the most points at the end when all tiles have been placed. There is a pool of tiles in the centre of the table, and each player has a hand of 5 tiles. Each time a tile is placed, the player draws back up from the pool. On each turn a player can play as many of their 5 tiles as they feel is advantageous - each tile played must adjoin a piece already on the board, and the numbers in each triangle of the tiles must add up to a total of 10. Scores are made for completing squares of 4 pieces, and should be added to the players score tally as soon as the square is completed.
