We do not support, facilitate, promote, or encourage real-money sports betting, gambling, or wagering of any kind. There are no entry fees, no virtual currency purchases, and no real-money prizes or payouts. All predictions, scores, and badges earned on this platform have zero monetary value.
1. Terms of Service
Welcome to CupUndo ("the Service"). By accessing or using our website, you agree to comply with and be bound by these Terms of Service.

We enforce unique guest nicknames to ensure correct leaderboard calculation. We reserve the right to delete guest records at any time to prevent spam or namespace squatting.
