36.TH SNAKE 6 "May 31, 1993"

38.SH NAME
39snake, snscore \- display chase game
40.SH SYNOPSIS
41.B snake

43.B -w width
44] [
45.B -l length
46]

48.B snscore
49.SH DESCRIPTION
50Snake is a display-based game which must be played on a CRT terminal.
51The object of the game is to make as much money as possible without
52getting eaten by the snake. The
53.B \-l
54and
55.B \-w
56options allow you to specify the length and width of the field.
57By default the entire screen (except for the last column) is used.
58.PP
59You are represented on the screen by an I.
60The snake is 6 squares long and is represented by S's.
61The money is $, and an exit is #.
62Your score is posted in the upper left hand corner.
63.PP
64You can move around using the same conventions as vi(1),
65the h, j, k, and l keys work, as do the arrow keys.
66Other possibilities include:
67.IP sefc
68These keys are like hjkl but form a directed pad around the d key.
69.IP HJKL
70These keys move you all the way in the indicated direction to the
71same row or column as the money. This does
72.I not
73let you jump away from the snake, but rather saves you from having
74to type a key repeatedly. The snake still gets all his turns.
75.IP SEFC
76Likewise for the upper case versions on the left.
77.IP ATPB
78These keys move you to the four edges of the screen.
79Their position on the keyboard is the mnemonic, e.g.
80P is at the far right of the keyboard.
81.IP x
82This lets you quit the game at any time.
83.IP p
84Points in a direction you might want to go.
85.IP w
86Space warp to get out of tight squeezes, at a price.
87.PP
88To earn money, move to the same square the money is on.
89A new $ will appear when you earn the current one.
90As you get richer, the snake gets hungrier.
91To leave the game, move to the exit (#).
92.PP
93A record is kept of the personal best score of each player.
94Scores are only counted if you leave at the exit,
95getting eaten by the snake is worth nothing.
96.PP
97As in pinball, matching the last digit of your score to the number
98which appears after the game is worth a bonus.
99.PP
100To see who wastes time playing snake, run
101.I snscore .

109.SH BUGS
110When playing on a small screen,
111it's hard to tell when you hit the edge of the screen.
112.PP
113The scoring function takes into account the size of the screen.
114A perfect function to do this equitably has not been devised.
