Try to expose every square in the grid that is not one of the hidden mines, without opening any square that is a mine.
Click in a square to open it. Every opened square are marked with the number of mines in the surrounding 8 squares, if there are any; if not, all the surrounding squares are automatically opened.
Right-click in a square to mark it with a flag if you think it is a mine. If a numbered square has exactly the right number of flags around it, you can click in it to open all the squares around it that are not flagged.
The first square you open is guaranteed to be safe, and (by default) you are guaranteed to be able to solve the whole grid by deduction rather than guesswork. (Deductions may require you to think about the total number of mines.)
We hope that the free math worksheets have been helpful. We encourage parents and teachers to adjust the worksheets according to the needs of the child. For more difficult questions, the child may be encouraged to work out the problem on a piece of paper before entering the solution. We hope that the kids will also love the fun stuff and puzzles.
