Bomb handling Ext app for iPhone and iPad

Minesweeper is a game that aims to discover "mines" hidden in the map and open all squares except mines on the map.
Set a flag in the place where you thought it was a land mine. To set the flag, you can set it by long press.
The place where I thought that there was no land mine touches. If there is a land mine at the touched location, it will explode and the game will be over.
The map can be scaled to any size in the configuration.
Achievements will be the time at which all landmines will be found. The ranking is displayed according to the size of the map.
I know about how to play Minesweeper, so I will omit it.
