The Battle Royale are very present in the IO games and today we bring you one of their great classics set in this game mode. The first IO games to triumph were Agario and Slitherio, the latter with a kind of worm that you had to grow and eliminate enemies to eat and gain more points. This game has been brought to the Battle Royale with this version in which we will have to guide the worm through the area delimited by a red circle, making it grow and ending with your rivals to be the last to be alive and get the victory royale. The circle will be closed which will make this Worm Royale IO even more crazy. Enjoy the game Worm Royale IO, it's free, it's one of our Battle Royale games we've selected.
