Description: This game is the combination of Hypersudoku and Sudoku X. In Hypersudoku there are an additional 4 groups of 3 x 3 squares that are coloured, and the numbers in these groups should also not duplicate. Finally the additional constraint of Sudoku X is applied, i.e. the numbers in each of the two diagonals should also not duplicate. As you can see there are more constraints and so you need to look at more places to decide which number should go to which square. It is more complicated and also more fun.
How to play : Use mouse to play the game.
