2. Classic

   Everyday Sudoku with the addition of scoring. The correctness of a cell is revealed as it is placed. If you get 3 wrong cells, you fail that puzzle! Cells are worth 9 times the current multiplier. Correct cells increase the multiplier by one. Any wrong cell resets the multiplier.

2. Cluster

   Same as Classic, except the correctness of a cell is not revealed until every cell in its region (one of the nine 3x3 groups of cells) has a value. If a cell is revealed to hold the wrong value, its correctness will become hidden when its value is changed to a new one.

2. Minefield

   Classic Sudoku with the addition of mines and bombs. A mine is a special cell that must be solved on the first try or you fail that puzzle. A bomb is a special cell that randomly appears with a 25-second timer attached to it. If that timer reaches zero, it counts as a mistake.

2. Friendly Match

   Play Sudoku against a friendly opponent! Same as Classic, except the correctness of a cell will never be revealed! Cells that only you have filled in are green, whereas orange cells are shared by your opponent. Blank, red cells are cells that only your opponent has filled in.
