Bonus Features in Diamond Duke

The Diamond Duke slot offers you 3 bonus features. They all stem from the wheel scatter as they’ll give you a spin on the Bonus Wheel where you can win big multipliers or entry to the Pick & Click feature for big cash prizes. If you spin the Multiplier Wheel, you can get a 10x multiplier which can lead to 100x multipliers overall.

Bonus Wheel feature

Keep an eye out for the wheel scatter symbol appearing. 2 of them will  give you 4 times your stake as well as triggering the Bonus Wheel feature.

You will then get 1 Bonus Wheel spin. The Bonus Wheel is above the reel set and will reward you a multiplier of 2x, 3x, 5x, 7x or 10x your stake. You can also land on the Star which triggers the Pick & Click feature.

Pick & Click feature

In the Pick & Click feature, you will come across prizes depending on your stake or bet:

  • Stage 1 = between 2 and 7 x stake
  • Stage 2 = between 3 and 15 x stake
  • Stage 3 = between 5 and 100 x stake

You begin in Stage 1 and make a pick. If you uncover the Collect option, the feature will end. If you unearth the Upgrade option, you will move to the next stage.

Multiplier Wheel feature

You can access the Multiplier Wheel feature by landing 3 wheel scatters in the base game. As well as a prize of 8 x stake, you’ll get 1 Bonus Wheel spin (described above) and 1 Multiplier Wheel spin. You then spin the Multiplier Wheel to win a multiplier of 2x, 3x, 5x, 7x or 10x.

The multiplier from the Bonus Wheel feature is combined with the multiplier from the Multiplier Wheel feature. This can lead to a 100x multiplier if you’re lucky.

You can also enter the Multiplier Wheel feature by filling the entire grid with the same symbol. If you were to do this with the high value diamond and landed a 100x multiplier, you’d win 16,000 x your stake.
