Understanding Wagering Requirements
Every welcome bonus comes with a wagering requirement — the number of times you must bet the bonus amount before you can withdraw it as real money. A 30x wagering requirement on a £500 bonus means you must wager £15,000 before cashing out.
Warning: A larger bonus is not always better. A 300% bonus with 50x wagering is harder to clear than a 100% bonus with 20x wagering. Always calculate the total playthrough required before claiming.
