Sonic Triple Trouble

Sonic the Hedgehog: Triple Trouble is a platform game developed by Aspect and published by Sega for the Game Gear in 1994. It is the sequel to Sonic Chaos and features classic Sonic series gameplay. The player can choose to control either Sonic the Hedgehog or Tails as they venture to protect the powerful Chaos Emeralds from others. Sonic and Tails can use items strewn across the stages, and differences in their abilities make for different gameplay experiences when playing as each character.

Gameplay:
Triple Trouble features classic Sonic series platforming gameplay. The story follows Sonic the Hedgehog and Tails in their efforts to stop others from obtaining the powerful Chaos Emeralds. Dr. Robotnik has tricked Knuckles the Echidna into helping his search; meanwhile, treasure hunter Nack the Weasel is also searching for the emeralds.

Players can control either Sonic or Tails through six different themed areas. Both characters play similarly, including the use of a spin dash move, but Sonic can perform a peel out while Tails can fly briefly. The player can use various items placed in the stages, such as spring shoes, underwater fins, and rocket shoes. Some can only be used by one character. The differences between Sonic and Tails results in their paths for traversing stages differing between one another.

The player collects rings as they explore the stages. When hit by an enemy, the player will lose 30 rings, or 50 if they touch a spike obstacle. In other Sonic games, the player would normally lose all their rings for any damage. If the player has 50 or more rings and destroys a box with a Chaos Emerald icon, they will be transported to a special bonus stage for an opportunity to obtain the gem. Some of these stages are labyrinth-like platforming stages while others have the player piloting a plane, collecting rings.
