Sudoku - the board game

Here's the perfect Christmas gift for my brother Wayne and his family. Rather than playing by himself (and incurring his wife's displeasure) they can now all join in - yes, it's Sudoku the Board Game! And it works with any Sudoku puzzle! And you can play with 3 or more other people! The box includes playing board, 81 number tiles, 32 page puzzle book and a dice. Wonder what the dice is for and how it (the game, not the dice) works.
