The ViperPC Port

The Viper races around the screen eating asterisks, and each one makes it two segments longer. It keeps moving the way you last pushed the stick, so the challenge is steering a head with an ever longer body behind it. Hitting a wall, the maze or your own body ends the game, and turning straight back onto yourself counts as a crash. Choose one of nine speeds and one of three courses: an open field, an easy maze worth twice the points, or a hard maze worth five times. Your score is the asterisks eaten times the skill level times the maze's factor. The Viper waits, still, until you first push the stick, and it stops growing once it is very long.

Controls: Use either joystick. Push the stick to turn the Viper, which keeps going the way it was last pushed; diagonals are ignored. In the menus the stick chooses and the button confirms. The keypad is not used.
