Pilot Mines is a little freeware application, modelled after an X11 minesweeper clone (which in turn was modelled after the original MS game).
The controls are fairly easy (if you know the game): tapping on a covered field will uncover it (like the left mouse button in the original game), tapping on an uncovered field does the same as pressing the middle mouse button in the original game, tapping on a covered field while pressing the page up or page down button toggles flagging that field (that's what the right mouse button does).
