These fights use the music from Sonic Lost World's Deadly Six boss fights and Sonic Adventure's Egg Hornet battle respectively. The game includes two boss battles, against Zazz and Doctor Eggman. Cream the Rabbit became a playable character though the Easter Global Challenge.

Rouge the Bat was later added as a playable character in the Fifth Global Challenge. Silver the Hedgehog became playable though the Christmas Festive Challenge. Blaze the Cat was also made playable through the second global challenge. Version 1.6 added two new areas: a beach (with boats around and killer whales overhead) and underwater tubes, as seen in Sonic & Sega All-Stars Racing. Shadow the Hedgehog was later added as a playable character as part of the first global challenge. Game Center is supported with Achievements and Leaderboards. The game records how many meters the player has travelled. Scenarios and sounds are based on Seaside Hill and Ocean Palace (from Sonic Heroes) and changes as the player progresses. The player can collect rings and avoid enemies and obstacles throughout the level. The game is a endless run and jump type game in which Sonic runs through the levels automatically.
