There have been many well-known snake game clones and similar games inspired by the classic Snake concept. Some of these clones and variations include:

1. Slither.io: A multiplayer online game where players control a snake-like avatar, consuming multicolored pellets to grow longer while trying to avoid colliding with other players' avatars.

2. Snake '97: A nostalgic recreation of the classic Snake game, designed to mimic the experience of playing the original version on old Nokia phones.

3. Snake Rewind: An updated version of the classic Snake game with enhanced graphics, power-ups, and different game modes.

4. Snake VS Block: A twist on the traditional Snake game where players navigate a snake through a series of numbered blocks, aiming to collect as many dots as possible while strategically breaking through numbered blocks.

5. Paper.io: While not exactly a Snake game, Paper.io shares similarities in gameplay mechanics. Players control a blocky character that leaves a trail behind it and must capture territory by enclosing areas without getting touched by other players.

These games provide modern interpretations of the classic Snake gameplay, offering new challenges and features while retaining the core mechanics that made the original game so popular.
