The Synth City Race was an event that started on December 17, 2022. It featured the introduction of the Invisible Espio skin and the new Stompdash mechanic. The event's premise was to clear the new Synth City Obby and find some secret goodies along the way. The event was made to promote RB Battles, a fan Roblox event where Roblox content creators fought against each other in a selected lineup of games.
The premium podium purchase for this update was removed due to some prior backlash

#Activate the switches!
##As the player progresses through Synth City, they must find 25 switches to interact with. Doing so was the only way to complete the obby.
##Uncover the Ninja's whereabouts
###Hidden on the rooftops of Synth City awaits a familiar Ninja Master's card; a hint is to look behind air conditioning units and orange ramps. Maybe prioritize buildings with both...

*"Hey, Challenger! Do you have what it takes to scale the tower? You'll need to find 25 of the 30 switches to unlock the capsule." Start of the event.
*"Not so fast! Did you find 25 switches yet? If not, you'll need to go back and search a bit more."– finishing with 24 or fewer switches.
*"So you made it to the top, huh? What about trying to beat your best time? Enter here to reset the Synth City Obby." Finishing with all switches.
==Trivia==
* Even though this event happens after the Sonic Prime Premiere event, the Permanent events were still disabled for unknown reasons.
*As the map (and the event as a whole) was used to promote RB Battles, as the game was part of the lineup of games to be used during the event, the game was used in the semifinal round between KreekCraft and Ominous Nebula.
