ksnakeduel 4:4.12.97-0ubuntu1 (i386 binary) in ubuntu trusty

 The object of the game is to avoid running into walls, your own tail,
 and that of your opponent, while at the same time you have to try to
 get your opponent to run into them.
 .
 KSnakeDuel also includes kdesnake, a special mode of the game where
 you can play the classical snake action game. In snake you steer a
 snake which has to eat food. While eating, the snake grows. But once
 a player collides with the other snake or the wall, the game is
 lost. This becomes, of course, more and more difficult the longer the
 snakes grow.

 This package is part of the KDE games module.
