Below we will give you a breakdown of the three different bonus tiers:

  • On your first deposit: Enjoy a first-time deposit bonus of 100% up to €666 and 66 Bonus Spins on the Guns ‘n Roses slot by NetEnt

Wicked Welcome Bonus (UK)

Players from the United Kingdom will enjoy a slightly different bonus, so as not to feel left out.

While casino players from Europe and casino players from the rest of the world will enjoy a three-tiered welcome bonus, players from the UK will enjoy a six-tiered welcome bonus. Every deposit bonus will net you up to £66 in bonus cash as well as 66 Bonus Spins on Book of Dead by Play ‘n Go on the first deposit.
