Snake.is - it is great combination of the classic "Snake" game, popular multiplayer game "Agar.io" and racing game "TRON". Also it's improved 3D version of the "Slither.io" game.
Move a snake around a dark space, eat mass, defeat and consume other players to grow the biggest and longest in the game. If the player's snake's head collides into a part of another snake, the player loses the game and must start over. The defeated avatar's body turns into bright, shining dots for other players to consume.
By clicking the mouse, the player can activate "boost mode", which causes the avatar to speed up.

Good luck and have a fun!
