Help and contact

Contact support

Use the form below for anything about your account, a payment, a hand, an event, a promotion, fair play, responsible gaming, privacy or a technical problem. It reaches the room's support inbox whether or not you are signed in. Include the hand, transaction or event id, and roughly when it happened in Eastern time, which is how every time on Riverline is written.

Riverline staff will never ask for your password, your authenticator code or your recovery codes.

Account and sign-in

Sign in with your username or email and password, or by proving ownership of a linked wallet. Two-factor authentication with an authenticator app is set up in Account → Security and is required for every withdrawal.

• Lost your authenticator: use one of the recovery codes issued at enrolment.
• Lost your password: use the reset link on the sign-in page.
• Suspicious session: Account → Sessions lists every device and lets you sign any of them out.

Deposits and withdrawals

Deposit USDC to the address the cashier generates for you on Polygon. Your balance is held in US dollars: the deposit is credited in USD at the exchange rate in force when it confirms, after the confirmations shown for that chain, and the cashier shows that rate and when it was last checked. Withdrawals are stated in USD and paid out in USDC at the rate you are quoted, go to a verified address, require your authenticator code every time, and are held for 24 hours when the address is new. The withdrawal policy explains the timings.

A hand you want reviewed

Open the hand in Hand history and use Replay to see the settled action. The deck for that hand was committed to before it was dealt; how the commitment works is on the shuffle page, and a public per-hand lookup is in cryptographic review rather than open. If you believe a rule was misapplied, contact support with the hand ID; decisions follow the house rules.

Limits and taking a break

Deposit, loss, wager and session limits, cooling-off and self-exclusion are in Account → Limits. A decrease takes effect immediately; an increase waits a day, and Account → Limits shows it waiting with the date it starts — your current limit holds until then, and setting a tighter one cancels it. Self-exclusion closes every session and cannot be reversed during the period you choose.

Report a security issue

If you find a vulnerability, report it privately through the form above — choose Security vulnerability — rather than in chat or a public channel. There is no paid bounty programme; what we do in return is set out in Security and fair play.
