/usr/games/snake [ -wn ] [ -ln ]
Snake is a display-based game which must be played on a CRT terminal
from among those supported by vi(1). The object of the game is to make
as much money as possible without getting eaten by the snake. The -l
and -w options allow you to specify the length and width of the field.
By default the entire screen (except for the last column) is used.
You are represented on the screen by an I. The snake is 6 squares long
and is represented by S's. The money is $, and an exit is #. Your
score is posted in the upper left hand corner.
You can move around using the same conventions as vi(1), the h, j, k,
and l keys work, as do the arrow keys. Other possibilities include:
sefc These keys are like hjkl but form a directed pad around the d
HJKL These keys move you all the way in the indicated direction to
the same row or column as the money. This does 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.
SEFC Likewise for the upper case versions on the left.
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.
x This lets you quit the game at any time.
p Points in a direction you might want to go.
w Space warp to get out of tight squeezes, at a price.
! Shell escape
^Z Suspend the snake game, on systems which support it. Otherwise
an interactive shell is started up.
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 (#).
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
As in pinball, matching the last digit of your score to the number
which appears after the game is worth a bonus.

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