Serpento

Serpento is a Snake game with a unique twist: consuming every apple is only half the challenge. Once the board is cleared, a door slides open in the wall, and you must guide your entire tail through it to finish the level. Its 24 stages range from open fields to tight two-tile mazes, featuring pits that teleport you across the board and frogs that leap away as you approach. There are three speed settings, four control layouts, and a best score recorded for each stage.

A simple click or tap is all you need to start playing.
