+.Nm snscore
+.Sh DESCRIPTION
+.Nm
+is a display-based game which must be played on a CRT terminal.
+The object of the game is to make as much money as possible without
+getting eaten by the snake.
+The
+.Fl l
+and
+.Fl w
+options allow you to specify the length and width of the field.
+By default the entire screen is used.
+The
+.Fl t
+option makes the game assume you are on a slow terminal.
+.Pp
+You are represented on the screen by an I.
+The snake is 6 squares long and is represented by s's with an S at its head.
+The money is $, and an exit is #.
+Your score is posted in the upper left hand corner.
+.Pp
+You can move around using the same conventions as
+.Xr vi 1 ,
+the
+.Ic h ,
+.Ic j ,
+.Ic k ,
+and
+.Ic l
+keys work, as do the arrow keys.
+Other possibilities include:
+.Bl -tag -width indent
+.It Ic sefc
+These keys are like hjkl but form a directed pad around the d key.
+.It Ic HJKL
+These keys move you all the way in the indicated direction to the
+same row or column as the money.
+This does
+.Em not
+let you jump away from the snake, but rather saves you from having
+to type a key repeatedly.
+The snake still gets all his turns.
+.It Ic SEFC
+Likewise for the upper case versions on the left.
+.It Ic ATPB
+These keys move you to the four edges of the screen.
+Their position on the keyboard is the mnemonic, e.g.
+P is at the far right of the keyboard.
+.It Ic x
+This lets you quit the game at any time.
+.It Ic p
+Points in a direction you might want to go.
+.It Ic w
+Space warp to get out of tight squeezes, at a price.
+.El
+.Pp
+To earn money, move to the same square the money is on.
+A new $ will appear when you earn the current one.
+As you get richer, the snake gets hungrier.
+To leave the game, move to the exit (#).
+.Pp
+A record is kept of the personal best score of each player.
+Scores are only counted if you leave at the exit,
+getting eaten by the snake is worth nothing.
+.Pp
+As in pinball, matching the last digit of your score to the number
+which appears after the game is worth a bonus.
+.Pp
+To see who wastes time playing snake, run
+.Nm snscore .

+.Sh BUGS
+When playing on a small screen,
+it's hard to tell when you hit the edge of the screen.
+.Pp
+The scoring function takes into account the size of the screen.
+A perfect function to do this equitably has not been devised.
