How to redeem codes

Mansion of Wonder uses a reverse code system - instead of entering a code to receive in-game rewards, you play through the experience and complete the creation challenges to earn codes for free Roblox avatar accessories. After finishing the activities, visit rblx.co/wonder in your browser to retrieve the codes you have unlocked.

The three items available are the Head Slime Hat (GLIMMER code), the Tomes of the Magus shoulder accessory (PARTICLEWIZARD code), and the Ring of Flames waist accessory (BOARDWALK code). These are standard Roblox promo codes redeemed at roblox.com/promocodes or in the Roblox app under Promo Codes - not inside the game itself.

All three codes are permanently active with no expiration date, so there is no time pressure. Because Roblox Corporation created the experience as part of an official education campaign, these codes are stable and have remained valid since the June 2021 launch.
