Stop the slot while a withdrawal is still only pending

Withdrawal requests stay pending until the casino moves them. During that wait, an open online slot is still a live debit against the same balance. A new stake can cancel the cash-out under the cashier rules, or it can be taken from money you meant to withdraw. Both results look like a betrayal of the cash-out button. Both are what the software does when play continues. The pending line is not a locked envelope if the game is still spinning.

A new stake can cancel the request or spend it

Close the slot. Return to the cashier and read the request: amount, status, and time. If the line is intact, leave it intact. Do not open a second game to pass the time, and do not claim a bonus that requires wagering, because wagering is the opposite of a withdrawal. Crypto cash-outs add a chain wait after the casino approves them. That later wait is not a reason to gamble the balance back. Approval, then the network, then the wallet: those steps are easier to see when the slot is shut.

Wait until the cashier still shows the cash-out

If you already spun and the pending amount dropped or vanished, stop and read the transaction list before you send another deposit. The list will show whether the request was cancelled and whether the stake took the funds. A progressive jackpot win credited just before the cash-out is part of the same balance. It is included in the withdrawal only if it was in the request and the request is still there. Refresh the cashier. If the request is whole, do nothing else in the lobby until it leaves the pending state.
