Sudoku is a simple yet highly addictive logic puzzle game. Simply complete the board ensuring that each row, each column and each sub-grid only contains one instance of each piece. At the start of a game a number of pieces are placed on the board. These are known as ‘givens’. The remainder of the board contains blank squares for you to complete. You will need to use all your powers of deductive reasoning to solve the unlimited supply of boards that Sudoku can generate. Sudoku supports the ability to mark each board square with possible moves to aid in the puzzle solving. Sudoku also supports the ‘cross hatch’ marking aid to solving puzzles. All boards generated are symmetrical and have a single solution making them pure game boards. Sudoku also supports the popular game variation whereby the diagonals may only contain one instance of each piece. Sudoku includes a lightning fast puzzle solver able to solve any external puzzle. Simply enter any external puzzle and request the solver to find a solution.
