Press "Press here to start!" On the title screen to start the game. Click the square that appears first. The square that is opened by clicking shows how many bombs are loaded around the square. 0 if nothing is displayed. Predict which square has the bomb from that number and the open square, and find the square without the bomb. It is clear when you open all the squares without bombs. However, if you open the square with the bomb on the way, the bomb will explode and the game will be over. You can also mark the squares with bombs while playing the game. You can switch between the mode to open the square and the mode to mark the place where the bomb is located with the Open button and Check button. You can also change the difficulty level of the game from the title settings to make the game more enjoyable.
