Why Are My Codes Not Working?
Codes won't work unless you type them in the same way as they appear on the list. Make sure that your capitalization is correct and that you don't miss out a letter or leave an extra space. Additionally, the codes are one-time use only and may expire at any time.
If you're struggling with getting the "Claim" button to work correctly, try clicking in its bottom-right corner. It's layered just over the Roll button, so clicking in the center opens that menu by default.
