Yes, you can withdraw bonus money, but only after meeting specific conditions. Typically, online casinos require you to fulfill wagering requirements—meaning you must bet the bonus amount a certain number of times before it's eligible for withdrawal. For example, a £50 bonus with a 30x wagering requirement means you'd need to wager £1,500 before cashing out. Additionally, not all games contribute equally toward these requirements; slots often count 100%, while table games may contribute less. Time limits also apply, so it's crucial to read the terms and conditions carefully. I learned this firsthand when exploring bonuses on lucky-spins.org; understanding the rules helped me make the most of the offer.
