What are the most popular Sonic games online?

The most popular Sonic games online generally fall into three categories: the classics, endless runners, and fan-made creations.

• Classic Retro Games: Many sites offer browser-based emulations or versions of the original Sega Genesis titles, such as Sonic the Hedgehog 1, 2, and 3 & Knuckles. These are the definitive 2D speed-platformers.

• Endless Runners (Mobile-Style): Games like Sonic Dash and Sonic Forces: Speed Battle are incredibly popular. These are free-to-play mobile games (also played on PC via platforms like Steam or mobile emulators) that focus on high-speed, lane-based dodging and collecting rings.

• Fan Games and Hacks: The community keeps the online scene vibrant with thousands of fan-made games, often featuring unique twists, characters, or level designs that are free to play in a browser or download, such as the well-known Ultimate Flash Sonic (a classic in the browser gaming space).
