Zapper.io is a cool multiplayer snake IO game which you can play online and for free on Silvergames.com. This game offers you that good old classic game mode about eating orbs to grow and kill other players by head contact to become the biggest snake on the map. Also, you can play the Zapper mode, in which you can only kill smaller players and be killed by larger ones.
Zapper has a more modern look than other similar games, with a new kind of electric worm or snake slithering around. You can use the purple electric lines to get free speed boosts, so use it to your advantage and go kill them all to unlock creatures and achieve goals. Become the deadlies snake on the map and try to stay alive at all cost! Have fun with Zapper IO!
