Ring of Fire is an Accident mini-game in Sonic Shuffle. It can randomly occur by accident in Nature Zone.
Everyone stands on a large platform while rings of fire pass by. Inside the rings are regular Rings and occasionally a Forcejewel. Players must jump through the rings of fire to collect the Rings without touching the flames, as doing so will result in a loss of Rings. Some fire rings rotate, making it trickier to get the Rings, but these are the ones that usually hold Forcejewels. As the game continues, the platform rises and lowers. When the platform is up, some rings don't have to be jumped through while others are so low that they are unattainable.
When time expires, the player who collected the most Rings gets a 20-Ring bonus while second place gets 10 and third gets 5.
