If you win with Bitkingz Casino’s no deposit Free Spins, you must wager $0 to convert your winnings to real money. This is because Bitkingz Casino’s no deposit Free Spins come with a 45x wagering requirement.
Free Spins win x a 45x wagering requirement = $0 to wager.
So, once you’ve staked a total of $0, any remaining bonus fund will be transferred to your cash balance. However, since the Free Spins also come with a $50 win cap, you can’t cash out more than $50 of your winnings.
