Snafu

Snafu is an arcade action game similar to the Atari game Surround. You control a constantly moving and growing wall; the goal is to trap all of your opponents before you become trapped yourself. If you crash into the borders of the screen, into another player's wall, or your own wall, you are out for that round. The last player left standing wins the round! Several game options are available which allow or forbid diagonal movement, set obstacles in the playfield, allow a player's wall to disappear or remain on the screen after they crash, control the speed of movement, and select the number of rounds to play. The game can be played by one or two human players, and optionally two additional computer players can be added for up to four players on the screen at a time.

Also included is a two player only game where you control a serpent containing 10 links, and your goal is to bite the links off of your opponent one at a time. Only the very last link of the serpent can be bitten off, so you need to be sure you keep your tail away from your opponent! The screen walls and the player's links are non lethal if you crash into them in this variation, however if you double back accross your own path you will lose a link. The first player to bite off all of his or her opponent's links wins.
