Here is a little game that I coded up, based on a Mac game that I
enjoyed. Although the game is a derivative work, based on someone
else's idea, the sources are original, and may be freely used in any
way. (I think I'm safe stealing this guy's game idea, since he offers
to give away his sources for the Mac version for free.)

Have fun.

XThe mines game is played on a grid. Every cell of the grid either has
Xa bomb on it, or it doesn't. If you move onto a cell that has a bomb
Xon it, you lose your leg. If you move onto a cell that doesn't have a
Xbomb on it, a integer between 0 and eight will be displayed, letting
Xyou know how many bombs are in cells adjecent to the one you just
Xmoved to. (Adjecent, in this game, means one cell away in any
Xdirection: up, down, left, right, or diagonal.) Zeros are displayed
Xas blanks, to avoid cluttering the display. Additionally, since you
Xcan obviously move in any direction from a zero, you automatically
Xclaim the territory adjacent to cells which are blank. You are only
Xallowed to move to cells adjacent to ones you already own. Cells you
Xown are indicated by being printed in black; ones you don't own are in
Xwhite. The object of the game is to (eventually) claim the lower
Xright hand corner of the grid.
X
XThe left button is for claiming new territory. The right button
Xstarts a new game. The middle button displays a bomb. This is a note
Xto yourself about where you think a bomb is; there is no feedback as
Xto whether you have guessed right or not.
X
XKeyboard entries:
X'n' gives you a new game.
X'q' quits the program.
X's' cheats. plays the game with the same information you have
X and some very simple rules. Doesn't win every winable
X game, but it does save stupid mistakes.
X
XThe slider at the bottom of the window is for adjusting how many mines
Xyou have in the grid. You can also resize the window if you want to
Xplay on a grid of a different size. The maximum number of bombs you
Xcan have is half the number of cells in the grid.

X.SH NAME
Xmines \- play in a mine field
X.SH SYNTAX
X.B glcheck
X.SH DESCRIPTION
X
XThe mines game is played on a grid. Every cell of the grid either has
Xa bomb on it, or it doesn't. If you move onto a cell that has a bomb
Xon it, you lose your leg. If you move onto a cell that doesn't have a
Xbomb on it, a integer between 0 and eight will be displayed, letting
Xyou know how many bombs are in cells adjecent to the one you just
Xmoved to. (Adjecent, in this game, means one cell away in any
Xdirection: up, down, left, right, or diagonal.) Zeros are displayed
Xas blanks, to avoid cluttering the display. Additionally, since you
Xcan obviously move in any direction from a zero, you automatically
Xclaim the territory adjacent to cells which are blank. You are only
Xallowed to move to cells adjacent to ones you already own. Cells you
Xown are indicated by being printed in black; ones you don't own are in
Xwhite. The object of the game is to (eventually) claim the lower
Xright hand corner of the grid.
X
XThe left button is for claiming new territory. The right button
Xstarts a new game. The middle button displays a bomb. This is a note
Xto yourself about where you think a bomb is; there is no feedback as
Xto whether you have guessed right or not.
X
XKeyboard entries: 'n' gives you a new game. 'q' quits the program.
X's' cheats. plays the game with the same information you have and
Xsome very simple rules. Doesn't win every winable game, but it does
Xsave stupid mistakes.
X
XThe slider at the bottom of the window is for adjusting how many mines
Xyou have in the grid. You can also resize the window if you want to
Xplay on a grid of a different size. The maximum number of bombs you
Xcan have is half the number of cells in the grid.
