Sudoku Sweeper
A combination of Sudoku and Minesweeper.
A cross between Sudoku and Minesweeper. Click a blank cell: if only one number can go there, given the numbers already showing, it’s filled in and you score points. If several numbers could fit, you uncover a bomb instead. The more bombs you uncover before revealing a number, the fewer points it’s worth, so the trick is to reason carefully before you click.
