Sonic the Hedgehog platforming of the main levels. The 16-bit "Sonic the Hedgehog " consisted of a giant rotating maze, which many considered a major technical achievement. The most common special stages, however, were segments with the character running through a long tunnel to collect certain items. 3D "collect item" levels, as in "Sonic 3" and "Sonic & Knuckles", used the same perspective but had Sonic collecting all the blue-colored orbs on the surface of a giant sphere. Finally, "Sonic Advance 2" employed a 3D ring-collecting stage, and "Sonic Chaos" ("Sonic and Tails" in Japan) used a variety of gimmicks for its levels.
Sonic the Hedgehog produced by OuiDo! Productions and will begin airing 11-minute episodes on Cartoon Network in Fall 2014. On February 6, 2014, Sega announced that "Sonic Boom" will become a separate franchise in the "Sonic the Hedgehog" universe.

Cartoon Network began to air the series starting from November 8, 2014.
