The Blue Blur is officially turning 35, and SEGA is throwing the ultimate digital bash. Starting yesterday, June 10, and running until July 8, 2026, the Sonic 35th Anniversary event is officially live in Sonic Rumble Party.
If you haven’t jumped into SEGA’s chaotic toy-world battle royale yet, there has never been a better time to download it on iOS, Android, or PC. The developers are rolling out the red carpet with exclusive, limited-time anniversary items, legendary skins, and nostalgic callbacks that any lifelong Sonic fan will appreciate.
Here is everything you need to know about the Sonic 35th Anniversary celebration and how you can score the best loot before the event wraps up this July.
Unlocking The Sonic 35th Anniversary Season Pass Rewards
SEGA is making sure every player walks away with some birthday gifts by introducing two distinct tiers for the event’s Season Pass. Whether you are a free-to-play casual or a dedicated collector, there is something here for you.
The Free Pass
Just by logging in and completing challenges during the event, you can claim:
- Party Sonic Skin: A festive look for the world’s fastest hedgehog.
- Party Koco Buddy: A adorable, celebratory companion to follow you into battle.
The Premium Pass
For players looking to upgrade their style, the Premium Pass unlocks deep-cut franchise history, including:
- Classic Sonic Skin: The iconic, shorter 90s design that started it all.
- Lock-On Cartridge Buddy: A brilliant nod to the revolutionary Sonic & Knuckles Genesis cartridge.
Exclusive Legendaries Hit The Red Star Ring Shop
If you have been hoarding your Red Star Rings, now is the time to spend them. The in-game shop has received a massive refresh specifically for the Sonic 35th Anniversary event.
The limited-time lineup includes some of the most unique cosmetic variants we have seen in Sonic Rumble Party since its launch in late 2025:
- King Sonic Skin: Rule the racetrack in royal attire.
- King Shadow Skin: Ultimate power meets ultimate royalty.
- Birthday Eggman Skin: Even the Doctor gets a festive makeover for his nemesis’s big day.
- Genesis Buddy: Run alongside a miniature version of the 16-bit console that birthed a legend.
What Is Sonic Rumble Party?
For the uninitiated, Sonic Rumble Party is SEGA’s fast-paced multiplayer party game where players dive into a whimsical toy world built by Dr. Eggman. You control toy versions of Sonic, Tails, Knuckles, Shadow, and other iconic heroes and villains, competing across more than 100 stages—including legendary zones like Green Hill and Chemical Plant.
With full crossplay support between mobile and PC, you can jump into two core game modes:
- Party Rumble: A casual, chaotic obstacle course frenzy.
- Ring Survival: A highly competitive showdown where only the richest and quickest survive.
The event is live right now across all platforms. Head over to the official [Sonic Rumble Party Website](https://Sonic Rumble Party.sega.com/en/) or check out the SEGA Asia Facebook Page to join the global celebration.
