Slither.io was the next huge io game hit after Agar.io. You are a snake, and you eat small shiny cells, and kill other players by cutting off other snakes (players) and eating all of the mass that is left behind after they die. Tip: The best are is around the edges of the map when you are small. Eat other snakes that get caught out of position and are easy prey. Try to protect your snake’s head because whenever you collide with someone, you die, they kill you, and they eat your remains. A good tactic is to look for other players that are tangled up and try to wrap around them and surround them, so they can’t get out.
