Sonic's Obstacle Mania is a platforming game developed by Blue Moon Studios and published by Sega. It was released on the Nintendo 3DS. The game follows Sonic, Tails, and Knuckles as they try to get through a series of obstacle courses inside a machine.


In each stage, the player controls either Sonic, Tails, or Knuckles and goes through a huge obstacle course while defeating enemies and avoiding traps. The goal of each stage is to get to the end of the course. When each stage is completed, a rank is given. In multiplayer mode, up to two players can play simultaneously.


At Eggman's base, Eggman and his henchmen create the Ultra Obstacle Course Machine to get rid of Sonic for good. After some finishing touches, the machine is complete and Eggman decides to type a letter to Sonic. Meanwhile, Sonic is waking up from his nap under a tree. Tails and Knuckles come by and show him the letter Dr. Eggman sent, which says that he is to go to Eggman's base for something "special". Curious of what the special thing is, Sonic goes over to Eggman's base with Tails and Knuckles tagging along. Once they get there, they see the Ultra Obstacle Course Machine. Sonic, Tails, and Knuckles then get sucked into the machine. Now they have to get through all the obstacle courses in order to get out of the machine.
