Sonic Jam is a game compilation that features levels inspired by three iconic Sonic games: Sonic 2 , Sonic 3, and Sonic & Knuckles . The player chooses one of these games to play, each with its own unique set of bosses and levels. For example, players can select from five levels based on Emerald Hill from Sonic 2, or Angel Island from Sonic 3 .
The game allows players to choose between Sonic, Tails, or Knuckles, each with their own special abilities. However, Knuckles is the only one without a gliding or climbing ability. Additionally, Sonic 3 's bonus stage is also included in the game.
