Sonic Rumble Party is kicking off a special collaboration in Thailand with bubble tea chain Jian Cha and ride-hailing platform Grab. The event runs from now until April 5, 2026, and gives players a way to earn in-game rewards through real-world purchases. The game is currently available on iOS, Android, Google Play Games, and Steam.

Players in Thailand can head to any Jian Cha store or place an order through GrabFood to get in-game rewards tied to their drink purchases. To mark the collab, Jian Cha has also rolled out two brand-new Sonic Rumble Party-themed drinks served in limited-edition cups featuring characters from the game. Every drink purchased at Jian Cha during the campaign period counts toward in-game rewards, regardless of which drink you pick.

The rewards rotate each week, so there’s reason to keep coming back:

• Week 1 (March 18 – March 24): Jian Cha Break Time Emote
• Week 2 (March 25 – March 31): Chrome Eggman Skin
• Week 3 (April 1 – April 5): Jian Cha Sticker Bundle

GrabFood users who order Jian Cha drinks through the app will receive an exclusive Grab Delivery Bag Buddy in-game item. This reward is available for the full duration of the collaboration. GrabUnlimited members get an extra perk where they can use GrabCoins on the Grab platform to redeem a special Grab Logo Sticker, an exclusive in-game item. On top of that, all GrabFood orders from Jian Cha also come with 20,000 Rings in-game.

Customers who buy at least one of the special collaboration drinks plus one additional drink of their choice (two drinks minimum on a single receipt) will receive a limited-edition collaboration coaster. This offer is capped at the first 600 qualifying customers per week, so it’s worth grabbing early.

Throughout the campaign, Jian Cha and SEGA will also run a social media giveaway where fans can win SEGA Fave plushies. More details on how to join are set to be announced, so players are encouraged to keep an eye on official channels.
