A really entertaining multiplayer fidget spinner game called Superspin.io. You are allowed to change the appearance of your fidget spinner before the game begins, from bright colors to badges.
The key elements in this game are glowing jewels. You can gradually boost the speed and size of your spin by gathering them. Watch out for opponents that are faster than you since they can take your jewels and even kill you if the gap is significant. Bump into other slower players to kill them and get their gems. Increase your speed to pursue other players and flee more quickly; this affects your current speed, so pay attention. Start off slowly and gradually gather gems to increase your speed. Until you are quick enough, avoid avoidable conflict; once you are, it's showtime!
