The Little Big Game of Moocho Sudooko

The Big Little Game of Moocho Sudooko turns sudoku puzzles into a board game. The board is a 9x9 square divided into 9 grids of 9. Each player gets 27 tiles (3 sets with the digits 1 to 9) in one of four colours. At the beginning of each turn the player rolls the dice and uses the result to decide which tile to play. A tile can be placed in any spot as long as there are not two identical numbers in the same row, column, or grid square. If the player cannot make a legal move, or the player does not play before the timer runs out, play passes to the next player. Play continues until there are no legal plays that can be made. (Alternatively, players may shift (but not remove) tiles to allow further plays.) The player with the fewest remaining tiles is the winner. In case of a tie, the numbers on the remaining tiles are added and the player with the lowest total wins.
