35x Wagering Requirement
The 200 free spins bonus at Griffon Casino is subject to a 35x wagering requirement. This means you must wager the total winnings from the free spins 35 times before they become eligible for withdrawal. These requirements can reduce the bonus’s real money value, as meeting the substantial playthrough conditions may be challenging for some players.

Generous Bonus Amount - 200 Free Spins
The 200 free spins offered by Griffon Casino are distributed across two titles: Big Bass Bonanza and Book of Dead. This bonus provides multiple opportunities to win, with spins spread over your first three deposits. While the number of spins is generous, you should note that winnings from the spins are subject to a 35x wagering requirement, which can affect the ease of withdrawing funds.
£100 Max Win Cap
Griffon Casino’s free spins bonus has a £100 maximum win cap. Any winnings exceeding £100 from the 200 free spins will be forfeited. Only up to £100 in winnings can be withdrawn, subject to fulfilling the 35x wagering requirement. This restriction significantly limits the potential real money value of the bonus, making it important to consider this cap when claiming the offer.
Total Bonus Cost - £60
Claiming Griffon Casino’s 200 free spins bonus requires a total of £60 spread across three deposits of £20 each. While the cost is clear, the need for multiple deposits differs from bonuses that only require a single deposit, which may be a consideration if you’re looking for simpler bonus structures.

An Average RTP Percentage: 96.71%
The free spins in Griffon Casino’s bonus apply to ‘Big Bass Bonanza’ and ‘Book of Dead’, which feature an RTP of 96.71% and 96.21%, respectively. Both RTP rates align with the industry average of 96%, offering fair gameplay and reasonable chances of winning for players.
As a bonus expert, I see Griffon Casino’s 200 free spins bonus as a solid offer for fans of popular games, providing a great chance to explore its slot collection. However, the 24-hour expiration on the spins and the £100 cap on winnings make it crucial to use them strategically. Add in the high wagering requirements, and while this bonus can deliver value, it’s best suited for players ready to plan their gameplay carefully to get the most out of it.
