Every game has some quests for which you will receive Soul Gems.

You can exchange your Soul Gems for Steam Wallet top-ups, game keys, CS:GO Skins and other rewards.
Limiteds are an amazing feature that Roblox added. You can trade very cool items with friends! You need Premium which is only $4.99 CAD. I recommend buying some premium hats because they could be very valuable in the future!
