Sonic Rumble Party is celebrating Sonic’s 35th anniversary with a new limited-time event packed with birthday-themed rewards.
The Sonic 35th Anniversary Event will run from June 10 at 8:00 AM UTC through July 8 at 7:59 AM UTC, giving players several weeks to progress through the Event Pass and unlock new anniversary items.

During the event, players can earn rewards such as the Birthday Party-themed Birthday Balloons effect, a 35th Anniversary icon, stickers, and more. Progress is earned by collecting XP from battles, while Event Missions will offer additional rewards, including enhancement materials for Skins and Buddies.
The Premium Pass will include the Classic Sonic skin and the Lock-On Cartridge buddy, adding a retro anniversary touch to the event lineup.
The Red Star Ring Shop is also being updated for the celebration. King Sonic, King Shadow, and Birthday Eggman will be available from June 10 at 8:00 AM UTC through July 8 at 7:59 AM UTC.



With event pass rewards, anniversary cosmetics, Classic Sonic, and new shop skins all arriving together, Sonic Rumble Party is giving players another way to celebrate the Blue Blur’s milestone year in-game.
