The Philippines Microsoft Rewards catalog currently offers Roblox Digital Cards for 840 Robux and 1,050 Robux, but not 100 Robux.^1^
A 100 Robux reward exists in Microsoft Rewards in some markets, but it is not currently listed in the Philippine catalog.^2^ Microsoft confirms that offers and redemption catalogs vary by country or region; the Philippines is a supported Rewards region, but that does not mean every reward denomination is available there.^3^
What you can do
- Redeem one of the denominations displayed on your Rewards page when you have enough points.
- Check the Redeem page periodically, because available Robux denominations can change or return after being unavailable, although there is no guaranteed restock date.^4^
- If you want confirmation for your particular account, submit the Microsoft Rewards Support form at https://rewards.bing.com/support.
- Do not change regions or use a VPN to access another catalog; use the market where your Microsoft Rewards account is registered.
Therefore, the missing 100 Robux choice is currently a Philippine catalog limitation, not necessarily a problem with your account.
