Sonic Speed Simulator Codes

Click the cog/gear icon in the top-right corner of the screen to open Settings, then click "Redeem Codes" in the top-right corner of the settings screen. Enter your code in the "Enter Code" text box and press the Redeem button. Codes are case-sensitive.

Codes reward a variety of items including exclusive Chao companions (like Bloxian Chao and Foxy Chao), emoji collectibles, stickers, temporary Ring Boost or Magnet Boost timers, Race Tickets, and occasionally full character skins. Most character unlocks come through the Fast Pass, events, and gameplay rather than codes, so the code rewards tend to be supplementary cosmetics and boosts.

Sonic Speed Simulator is relatively code-light compared to other Roblox games. The active inventory at any time is typically 1-5 codes, and many expire quickly after release. New codes drop with new events, Fast Pass season launches, and milestone celebrations. Primary sources are @GamefamStudios on Twitter/X, the official Discord server's #codes channel, and in-game announcements. Sega's own @Sonic_Hedgehog account occasionally cross-promotes major updates.
