What we can't help with
21blackjack is a play-money practice game. We can't help with accounts, deposits or disputes at any casino or gambling site, because we have no connection to them. We also don't accept paid placements for gambling operators.
If gambling is causing you problems, please contact a support service directly. In Australia, Gambling Help Online is free, confidential and available 24 hours a day on 1800 858 858.
