The reels, surrounded by skulls and a knight in armor, consist of medieval characters from A to 10 and 5 better paid skeleton warriors. The faceless Dark King is the most rewarding character. It will bring you a prize of 1, 7.5 or 25x your total stake if 3, 4 or 5 appear on a single payline. The same wins are also available with the blue wild circle, which substitutes for all characters except the scatter.

The Dark King: Forbidden Riches has been fully optimized for Apple iOS and Android devices. You will discover exactly the same simple gameplay and classic design in the mobile variety. The graphics are rather dark and we preferred to play on a larger screen. The free gambling game works well enough on mobile devices.

Bonus features

In this dark dream, wilds are the focus of most of the best action. If you manage to land them during Free Spins, they can boost your wins with multipliers and also become sticky.

Wild multiplier function

The shiny blue ball is the wild symbol in the gambling game. As you might expect, it substitutes for everything but the scatter when it is part of a winning combination. This ball also has some great houses that can actually help conjure up some coins.

Land more than 1 wild and a multiplier enters the game. Known as the Wild Multiplier feature, the multiplier value is equal to the number of wilds on the screen:

  • 2 wilds = 2x multiplier;
  • 3 wilds = 3x;
  • 4 wilds = 4x;
  • 5 wilds = 5x.

These multipliers are active both in the base game and during free spins.

Free Spins feature

A gorgeous red gemstone encased in gold is the scatter sign. Land 3 or more red gemstones during the same spin and you will activate the Free Spins feature of the free gambling game:

  • 3 scatters = 10 totally free spins;
  • 4 scatters = 12 free spins;
  • 5 scatters = 15 free spins.

In this feature, as in the base game, wilds are the key to success. During the completely free spins, you will see a series of characters on reels 2, 3 and 4 that are highlighted in the shape of a cross. This is the Hotspot Zone.

If you land a wild in the Hotspot Zone, it will become a sticky wild, turning that position into a wild for the rest of your free spins. Each sticky wild you hit adds 1 additional totally free spin to your total spin.

Wild multipliers are active during completely free spins also. With sticky wilds in play, there are some excellent opportunities to get multipliers on the move, especially if you land some wilds early in proceedings. During the free spins, you can land standard wilds on reels 1 and 5, as well as sticky wilds that can appear in the Hotspot zone on the middle 3 reels.


The Dark King: Forbidden Riches free gambling game is quite on the dark end of the dream theme. The creepy graphics and soundtrack are very well done. The gameplay isn't wild, but the particularly complex multiplier and free spins with sticky wilds are still a pretty powerful mix.

The key to big wins is the wild multiplier, which can reach 5x. With a maximum win of 500x the stake per spin, a 5x wild multiplier can result in 2,500x the total win rate. The style of play won't be for everyone, but if you like thrills and delights, then an encounter with Dark King: Forbidden Riches might be just what you're looking for.

RTP is 96.06%, which puts it in the middle of the pack when it comes to returns. Volatility is in the medium to high range, so expect smaller wins most of the time.

Is there a Dark King: Forbidden Riches free spins round?
