In a world full of Happy Snakes, you must show off your surviving ability to become the best snake of all. Happy Snakes is a multiplayer Slither Style IO game that is free in a browser. You have to roam through the big map trying to eat up as many scattered glowing dots as possible to increase your size. Getting bigger is always advantageous because you will be able to tackle other enemy snakes easily. You can utilize your big body to encircle the rivals, block their exits, then force them to run into you as they are unable to escape. Make sure that you defend the head of your snake all the time! Do not run into the body of any enemies or hit the map border, or else you will meet your doom. You can speed up to bypass other players, catch your targets as well as run away from the risks. Attempt to stay alive until you get to the top rank on the leaderboard.
