Play Sonic Autumn Mix Online

Sonic Autumn Mix is a fan made hack of Sonic the Hedgehog for the Sega Genesis, also known as the Mega Drive. It was created by dedicated members of the ROM hacking community, not by the original developer Sega. This release reworks the familiar levels of the first Sonic game, giving them a distinct seasonal theme that stands out among the many custom cartridges and digital files from that era.

You control Sonic, navigating him through remixed versions of Green Hill Zone and other early stages. The main objective remains the same: run from the left side of the screen to the right, jumping on robotic enemies and avoiding environmental hazards to reach the goal. Signature mechanics include building momentum to run through loops and inclines, as well as collecting rings for protection and extra lives. The pacing is brisk, demanding quick reflexes to dodge new enemy placements and traps, and the difficulty can feel uneven compared to the original. The experience feels like revisiting a familiar neighborhood that has been completely redecorated for a holiday.
