snake, snscore - display chase game SYNOPSIS
/usr/games/snake [ -wn ] [ -ln ] /usr/games/snscore DESCRIPTION
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 key. 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 worth nothing. As in pinball, matching the last digit of your score to the number which appears after the game is worth a bonus. To see who wastes time playing snake, run /usr/games/snscore . FILES

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 perfect function to do this equitably has not been devised. 4th Berkeley Distribution May 20, 1985 SNAKE(6)

snake4, snake4scores - Game starring a fruit-eating snake. SYNOPSIS
snake4 [-hHV] [-M file] [--help] [--highscores] [--version] [--merge-highscores=file] snake4scores DESCRIPTION
The snake4 program is my fourth implementation of the snake game, written for Unix and X11. Previous versions were written for MS-DOS. Move the snake around the screen and eat food. The snake grows in length as you eat. Avoid hitting the fence, eating lethal mushrooms and rotten food, and biting your own tail. Now and then a slim-pill will bounce around. If you eat this, you will get shorter, and you will gain bonus points for every length you loose. The bonus is also given when a round is over. When food starts blinking, it's about to rot. Rotten food is poisonous, and thus uneatable. As long as it blinks, it can still be eaten. Oh, yes - I almost forgot: You may be visited by the evil headbanger. Take my advice and run away from him before he hits you in the head! He won't stay long. The keys used to control the game are given at startup. snake4 features a site-wide highscore file. The file contains the top 200 users. Each user may appear once only in the highscore table. For technical reasons, snake4 connects to the X11 server before parsing options. This makes it impossible to eg. browse the highscore table using -H if no server is available. To be able to see the scores in such a case, snake4scores produces the same output as snake4 with option -H, but does no attempt on connecting to the X11 server. OPTIONS -h, --help Print a usage message on standard output, and exit successfully. -H, --highscores Dump the highscore list to standard output, and exit successfully. Starting snake4 with the name snake4score does the same thing, without first connecting to the X11 server. Note that this will possibly print more entries than the 20 or so that will fit within the game startup screen. -V, --version Print version information on standard output, then exit successfully. -M, --merge-highscores=file Merge separate highscore file file into the default highscore file, and exit successfully. Displays the new highscore table. This option is for the game owner or root only. X11 OPTIONS In addition to the above mentioned options, snake4 accepts the standard X11 toolkit options. AUTHOR
