Superspin.io (A multiplayer fidget spinner game similar to Agar.io) is called Superspin.io and combines aspects of other io games. Before you begin the battle, you have the freedom to modify the look of your fidget spinner in any way you see fit, from the neon color to the badge.
To win this game, you need to collect glowing jewels more than anything else. You can gradually grow the size of your spinning as well as its speed if you collect these items. You should intentionally collide with other, slower players in order to kill them and collect the gems they have, but you need also be wary of players who are faster than you because they can steal your gems and possibly even kill you if the speed gap is large enough. You can increase your speed to pursue other players and get away from them more quickly; this uses the speed of your current, so you need to pay care to it. Start off slowly and steadily build up your gem collection to increase your speed. Stay away from fights that aren't essential until you've built up enough speed; then it will be show time!
