Entertainment only
Mars Card Hall is for entertainment. Mission credits and scores have no cash value. There is no real-money gambling, wagering, prizes, purchases for chance outcomes, or cash-out. If real-money features were ever added, they would require separate legal review and disclosure — they are not present now.
Age
You must be at least 13 years old to use multiplayer features, including Quick Match and private tables.

- Cheating, exploiting bugs for unfair advantage, or service disruption
- Attempts to access another player’s seat, seat token, hidden cards, or private server state
