Minesweeper, just like in Microsoft Windows, except space substitutes for right-click. Enjoy! If you REALLY want to use right-click (ya know, for chording), then I recommend getting AutoHotkey and using a script like this: RButton::Space Esc::ExitApp 1 - Beginner 2 - Intermediate 3 - Expert 4 - Custom M - Toggle marks (?) C - Toggle color S - Toggle sound ↔↕ - Move the window around I - Show/hide seed for the current minefield
