To play Mine-Fields tap on New Game and then set the size of the playing field (number of columns, number of rows and number of mines) as well as the type of the playing field ? triangular, hexagonal or square. Then start the game. You can uncover a square by tapping on it. If you uncover a mine, you lose the game. If a number appears on a square, it indicates how many mines are there in the adjacent blocks that surround the numbered one. If there are no mines in the adjacent blocks, they will be opened automatically. To mark a square you suspect contains a mine, put a flag on it. If you are certain about the location of the mines indicated by the number in an opened block, you can open the remaining adjacent blocks with confidence. For example, if you put a flag beside a block marked 1, the remaining blocks adjacent to the block marked 1 must have no mines (if you put the flag correctly, of course), so you can open them.
