There's a great thread on the overall benefits of Microsoft Rewards here:

However for those interested in Roblox, I thought it was worth calling out that Microsoft Rewards recently added Roblox Digital Cards as a points redemption option.
The points exchange rate isn't great when compared to some of the other gift card options, but it is one of the few legit ways I've seen to get free Robux.
Plus, if you redeem a Roblox Digital Card from Microsoft Rewards by 12/31/24, you'll also receive a code for a free exclusive Bubbler Headphones UGC from Microsoft Rewards while supplies last.
The points exchange rate is 100 Robux per 1,500 points:
