is a 1997 racing game developed by Traveller's Tales and Sonic Team and published by Sega for the Sega Saturn. It is the third racing game in the Sonic the Hedgehog series, and the first to feature 3D computer graphics. The player races one of ten Sonic characters in various Sonic-themed race tracks as they attempt to stop Doctor Robotnik from stealing the Chaos Emeralds and enslaving the world. Sonic R features single-player and multiplayer game modes, and while similar to kart racing games such as Mario Kart, it places an emphasis on jumping and exploration. By collecting items and completing objectives, players can unlock secret characters. Development began after the completion of Sonic 3D Blast in 1996 and took nine months. It was the second collaboration between Traveller's Tales and Sonic Team and was designed to take advantage of the Saturn hardware. Sonic Team designed the race tracks, while Traveller's Tales handled implementation and programming using a custom game engine. The soundtrack was composed by Richard Jacques; Sonic R tracks, most notably "Super Sonic Racing", have been reused in subsequent Sonic games. Sega released the game for the Saturn in late 1997, for Windows the following year, and for the GameCube and PlayStation 2 as part of Sonic Gems Collection in 2005. Sonic R was the only original Sonic game released for the Saturn; Sonic 3D Blast is a port of the Mega Drive game, and Sonic Jam is a compilation of the first four mainline Sonic games. Initial reviews for the game were mixed, with retrospective reception being more negative. It was praised for its visuals and level design, but criticized for its controls and short length. Meanwhile, Jacques's soundtrack polarized audiences, who either found it catchy and well-produced or out of place in a racing game. Fan interest in Sonic R inspired Sega to revisit the racing genre with games such as Sonic Riders (2006). Gameplay Sonic R is a racing video game with single-player and multiplayer modes. The player selects a character and participates in a footrace on one of five race tracks, competing for the fastest time ahead of the other racers. Four characters are initially available, while the other six are secret characters that become available when the player completes certain in-game objectives. Although the gameplay is considered similar to kart racing games such as the Mario Kart series, Sonic R places an emphasis
