Serpentine is a 1982 action computer game developed by David Snider and published by Brøderbund. The gameplay and visuals are similar to that of Konami's Jungler, released the previous year. Serpentine was originally written for the Apple II  and ported to the Vic 20, Commodore 64 and Atari 8-bit computers.
The player controls (rides, by game description ) a multi-segmented blue 'good' serpent in a maze with the objective of eating all computer-controlled 'evil' (red or orange or green) serpents. Eating the tail segments of serpents makes them shorter, and a red or orange serpent turns green when shorter than the player. Hitting a green serpent headfirst eliminates it, and causes the player's serpent to grow an additional segment. Hitting a red or orange serpent headfirst causes the player's serpent to die. A frog appears at random intervals and gives any serpent eating it an additional segment. Once all opponents have been eliminated, the player's serpent automatically returns to a protected area.
As the game progresses, opposing serpents are faster and longer, increasing the difficulty, and each advancing level the existing players serpent gets slower. If the player's serpent dies, the replacement regains its original speed, but loses any additional segments gained by the previous incarnation.
One unique aspect of the game is how extra lives are gained. The playing serpent will lay an egg (losing a segment in the process) and, if given enough time, the egg hatches into another serpent, which hurries to the protected area. Enemy serpents will also lay eggs; if one hatches, a new two-segment opponent appears. It is possible to lose the last segment to an egg, resulting in the death of that serpent, but this can only happen to the player' serpent. If a frog happens to appear while an egg is on the map, it will head towards the egg and eat it as well. This will occur even at the end of a level when the player's serpent is operating on autopilot, making the choice of position where the last enemy serpent is killed tactically important.
Most versions of the game included 20 different mazes, but the Atari version only had 5.
