Sudoku is a popular puzzle game which is played as a duel. The playing field consists of 9 blocks, each containing 9 boxes. At the start of the game a few of the boxes contain numbers. It is your job to fill the boxes with numbers while ensuring that the numbers 1 to 9 only appear once per row and block.
The aim of the game is to completely fill the blocks in as few moves as possible. A hint costs you three moves and viewing the numbers which could fill a certain box counts as one move. The player with the fewest moves at the end of the game wins.
