You cannot withdraw bonus funds from your Pala Casino account because those funds are not technically equal to cash — they’re meant to be used to play your favorite games on the casino’s dime.
If you want to convert bonus funds to withdrawable funds, you must first play your favorite game and win. But you have to meet the play-through and wagering requirements for the bonus before you’re able to withdraw those winnings. You can check your account page to see what your withdrawable balance is and whether you have any active bonuses of which you still need to meet the play-through requirements.
