Vertical scrolling style minesweeper.
The numbers indicate how many mines are contained in the 8 neighboring cells. On/Off of a flag is made by carrying out the tap of the closed panel. A panel closed by the double-tap can be opened. When the tap of the number is carried out, and the surrounding number and number of a flag (mine) are the same, the panel except having stood the flag opens.
When you tap on the mine, you'll get a penalty. Uncover the cells using the number as a clue. When the un-tapped cells without a mine reach on the bottom line, the game is over.
