Onyx Slots Welcome Offer – Up to 100 Wager Free Spins


Do you like No Wagering Casinos? In that case I have some really good news for you! Onyx Slots is our newest No Wagering Casino. The total Welcome Package is a 100 Wager Free Spins Bonus, but it’s divided into different bonuses.

When you make a £10 deposit and wager this deposit you get your first 20 Wager Free Spins. You can do this 5 times and claim a maximum of 100 Wager Free Spins. All the 100 Free Spins are Wager Free, which means that you can keep the winnings and withdraw them immediately.

The Free Spins are available on the slot Zeus vs Hades Gods of War. This is one of the newer and most popular slots from Pragmatic Play. This is a high volatile slots, so you easily walk away with some interesting winnings! The Free Spins on Zeus vs Hades has a value of 10p per spin, so a £2 bonus every time you deposit and wager £10.

With the Free Spins you can win up to a maximum of £100. But with a high volatile slot like this it’s pretty fair that they add the maximum win of £100. Also keep in mind that you DON’T have to wager this bonus. All the winnings of the 100 Free Spins can be claimed and used to claim the next bonus.
