Roblox developer Gamefam and Sega are teaming up to create a unique Sonic the Hedgehog experience.

"Sonic Speed Simulator is the fastest game in Roblox and features everyone's favorite speedster, Sonic the Hedgehog," reads the official synopsis.

A free, surprisingly good-feeling Sonic game can't go amiss with fans in need of tiding over, but some underwhelming progression holds it back.

Sonic The Hedgehog is a massive hit on Roblox, and his game has seen an incredible 100,000 concurrent users in just two days.

If you're a fan of the old-school classic Sonic the Hedgehog and looking for a Roblox game that draws inspiration from the same universe, Sonic Speed Simulator is the perfect game.

SEGA and Roblox have finally collaborated to create the Sonic Speed Simulator.

Earlier today Sega announced a partnership with Gamefam to bring Sonic to Roblox in the brand-new game, Sonic Speed Simulator.
