XBomb is a variant of Minesweeper written by Andrew Bishop for X Windows. It is distributed under the GNU Public License.
XBomb is the most popular Minesweeper game for Unix and Linux systems, using X11 for the user interface. The original version was simply a clone of Windows Minesweeper with the standard three levels with 10, 40 and 99 mines. The first working version was completed 1994-11-08 as a result of the author deciding to program minesweeper to expand his UNIX skills1. Early in 1995 he added Triangle and Hexagonal grids to the game. This Version 2.0 was ready in May but not released until 1996 because the author did not have internet access at home1. Versions since then have added colour to the numbers and enabled the left click to be used as a chord. Highscores remember the best 10 scores with dates for each level and grid pattern, and time is kept to the millisecond.
Differences from the Windows version are that the 1.5 Click trick does not work, squares open when buttons are pressed not released, and F2 is not used to start games. You must also flag all mines to win.
XBomb was the first minesweeper version to use a millisecond timer. It also seems it was first to add other grid types such as Hexagons, but between the time these grids were added and the game publicly released, William Hause (USA) released Hex Minesweeper for Windows.
