SEGA, Gamefam, and The LEGO Group have teamed up for a massive crossover event. The Sonic Speed Simulator on Roblox is joining forces with LEGO, launching on August 9, 2025. Before the main festivities begin, however, players have some groundwork to do.

Your mission is to hunt for hidden LEGO bricks scattered throughout the world of Sonic Speed Simulator. Once players collectively gather enough bricks across all game servers, the portal to the special LEGO event will unlock. This is a collaborative effort, and your participation matters.

What can you expect from the Sonic Speed Simulator x LEGO collaboration?

Discover the new LEGO Brick Hill Zone, a vibrant area blending Sonic's iconic Green Hill style with the colorful, stud-filled LEGO universe. For three weeks, this zone will feature fresh missions, time-limited challenges, and exclusive collectibles.

Throughout the event, you'll be grinding on rails, demolishing LEGO Badniks, constructing structures, and taking control of powerful mech suits. The collaboration focuses on creative building, exploration, and cleverly thwarting Dr. Eggman's plans in fun new ways.

Starting August 9th, complete specific tasks like gathering LEGO Rings and Golden Bricks to unlock a series of LEGO-themed items. The reward pool includes digital versions of the LEGO Sonic and LEGO Tails minifigures.

Then, on August 16th, the Shadow Revenge Event begins. Partner with LEGO Shadow to hijack Dr. Eggman's colossal Egg Crusher Mech and deploy it in a new Time Attack mode. Rewards for this week include additional minifigures, such as LEGO Shadow and LEGO Metal Sonic, plus new color variants for the mech suit.

August 23rd introduces the Team Sonic Event. Hop into the Team Sonic Command Truck ATV and search for lost LEGO animals hidden around the Brick Hill Zone. The final reward wave features the LEGO Knuckles minifigure and the Knuckles Guardian Mech.
