The player controls Sonic and co. and they play like they do in the Genesis titles. Like in Sonic the Hedgehog CD, the player must use time poles (now adjusted to be instant) to travel through two different time zones, Past and Future. In the Past, Sonic must find the Special Stages and collect the Time Stones, while in the Future, Sonic must also find the Special Stages, however, these have the Chaos Emeralds. Beat all 14 Special Stages in each time zone (7 each) and the player will achieve the True Ending. Besides that, the player must traverse through 8 zones, most with 2 acts each, reach the Goal Post at the end, as well as encounter a boss at the end of the stage be it Metal Sonic or one of many loyal Super Badniks.
