High 65x Wagering Requirement
1/5
Online Casino London’s bonus comes with a 65x wagering requirement on any winnings from the free spins. This means you must wager 65 times the amount won from the bonus before withdrawing your winnings. This high wagering requirement can make it challenging to convert bonus winnings into real, withdrawable cash.
Explore our No Wagering Casino Bonuses for bonuses that let you withdraw your winnings without wagering.
Generous Bonus Amount
5/5
By spinning the Mega Reel, you have the chance to win up to 500 free spins on popular slot games like Starburst. The number of free spins awarded varies, providing an exciting range of potential bonuses to enhance your gameplay.
£250 Max Win Limit
3/5
Online Casino London’s bonus has a maximum bonus conversion equal to your lifetime deposits, up to a maximum of £250. This means you can convert bonus winnings to real money only up to the total amount you have deposited, capped at £250.
Fair Bonus Cost - £10 to Claim
4/5
You need to deposit a minimum of £10 to claim the bonus and spin the Mega Reel. This deposit amount is standard and offers an accessible way to participate in the promotion.
Explore our £1 deposit casino bonuses for offers requiring less money to claim.
An Average RTP Percentage: 96.09%
4/5
Starburst has an RTP of 96.09%, which is around the industry average for online slots. This means that, over time, the game is expected to return £96.09 for every £100 wagered, though actual outcomes will vary. Starburst delivers frequent but smaller wins as a low-volatility slot, making it ideal if you prefer a steady gameplay experience. With its expanding wilds and re-spins feature, this classic slot remains a favourite for simple yet engaging gameplay.
Overall, Online Casino London’s bonus provides an exciting chance to win up to 500 free spins on popular slots. However, the 65x wagering requirement and maximum conversion limit may make it difficult to withdraw large winnings. It’s an entertaining offer, but it’s important to be aware of the wagering conditions before you play.
