When comparing Onyx Slots's welcome offer of 100 Wager-Free Spins against similar UK casinos, it ranks #2 for bonus value and #1 for wagering requirements among our comparison group.
Standout Feature: Onyx Slots offers wager-free bonuses, meaning you can withdraw winnings without playthrough requirements. This is rare in the UK casino market and makes their offer particularly valuable for players who dislike wagering restrictions.
The N/A maximum bonus is competitive, though bet365 offers up to £30. Consider your planned deposit amount when choosing.
Good Pick
We like Onyx Slots for UK players, especially if you're after free spins. The no-wagering bonus is a big plus - not many casinos offer that.Works well for casual players and those hunting bonuses.

Signed up for the 100 Wager-Free Spins offer and it was easy to claim. No wagering is a nice touch. Got my cash out via debit card in about 3-5 days.
London · November 2025
Good range of slots - Starburst, Rainbow Riches, the usual favourites. Customer support sorted out a bonus query quickly on live chat.
Birmingham · October 2025
Payouts came through in a reasonable time. Plenty of games to pick from.

Onyx Slots is alright overall. The bonus was good but wish they had more payment options. Game selection is fine, nothing spectacular. Would be nice to see some live casino games added.
