Yamsweeper is a game to clear the field filled with bombs (mines). On the left top corner of the main window, the number of mines left is displayed. You can mark hidden mines underneath the panels, then the number is decreased. The number can be minus, but that means you have over-marked. On the right top corner, the time passed is displayed. The time counts up to 999 seconds. On center top, there's the symbol of yamsweeper. You can start a new game by clicking the symbol. A panel is opened with the left mouse button. If unopened panels are around the panel, and if they don't have mines underneath and around them, panels are also opened. This can happen like a chain reaction. Be careful; the game is over when you open a mine. If the panel opened has mines around, you will see a number varies from 1 to 8, which means the number of mines. For example, `1' tells you one of the panels around has a mine. `2' says that two mines are hidden next to. You can mark suspicious panels by the right button, which toggles the state of the panel between "Bomb" or "?" (in which it cannot be opened) and Normal. The middle button is assigned a special functionality. You can use the middle button to open the unmarked panels around, under certain conditions: - the panel you clicked is opened - the panel is not null, a number is displayed - the number of marked panels is equal to the number displayed on the clicked panel. Click the middle button on a opened panel. This port was created by Hidekazu Kuroki .
