CalcuttaCalc is not a betting service, and it can't be used as one. Operating real-money wagering through an app requires gambling licenses — we don't have them and the app is built so it never needs them: it cannot take, hold, move, or pay out money. It's a scorekeeper for private social auctions; whatever stakes exist live entirely between you and your group, offline. Social wagering laws vary by state and country — the organizer is responsible for keeping the game legal where they live. For participants 21+. If gambling stops being fun, call or text 1-800-GAMBLER.
