Spin Coaster (スピンコースター Supin Kōsutā?) is a gimmick that appears in Sonic the Hedgehog Triple Trouble. A variant of the Minecart, they are usually used by unnamed ladybug-like Badniks, but can be hijacked by the player and used for themselves.
Spin Coasters are circular-shaped, metallic vehicles with a yellow edge and two yellow wheels below their carrier. Usually, they are driven by unnamed ladybug-like Badniks.
In Sonic the Hedgehog Triple Trouble, Spin Coasters are typically only found in Sunset Park Zone, where they are piloted by Mobot-Bug looking enemies. On their own, the Spin Coasters can only hurt the player by running into the playable character.
The enemies riding the Spin Coasters can easily be defeated by Spin Jumping on them. With this Badnik having been taken out, the Spin Coaster will be left standing still without a driver. The playable character can then jump into the Spin Coaster, allowing them to ride the Spin Coaster around the Zone. When operating the Spin Coaster, the playable character first has to face the direction they want to head in with the Spin Coaster using the left or right directions on . Then, to make the Spin Coaster move in the chosen direction, the player has to continuously Spin Dash on them. The player can as well stop or even reverse the direction of the Spin Coaster by Spin Dashing in the opposite direction.
The player can make the playable character jump out of the Spin Coaster by pressing /. While the player is unable to make the Spin Coaster jump by itself, it will jump when it is launched off ramps. While riding it at high speed, the Spin Coaster can also easily smash through Badniks, breakable walls, and even obstacles such as spikes. However, the Spin Coaster will be destroyed if the player hangs around on a piece of exploding ground for too long or if it simply collides with an unbreakable wall.
Noticeably, Sunset Park Zone Act 2 begins with the playable character riding a Spin Coaster that will be launched off a ramp and then get destroyed upon colliding with an unbreakable wall. They also appear in the Time Attack for Sonic the Hedgehog Triple Trouble, where they are located on the Zone's lower paths so the playable characters can ride them.
- If the player keeps going on when the Spin Coaster comes to the hall full of up-aiming red springs, the Spin Coaster will glitch if it touches one of the springs, as the player has to hop off the cart.
