KMines is a minesweeper game for KDE, originally created in 1996 (latest release August 25, 2005 2.1.10) by Nicolas Hadacek under the GPL. See the homepage. It has three default sizes, "easy" (8×8), "normal" (16×16), and "expert" (16×30), as well as custom levels. The custom levels can have dimensions from 5×5 to 50×50 squares. It is possible to play with just the keyboard. The colors, mouse buttons, and tile sizes are configurable. Some cheating features are built in, together with a solver, an adviser, and the "Magic reveal" mode (only for non-trivial cases). World-wide high scores are available on the official site.
