It’s rare for a slot professing to have a foreboding, scary theme to live up to the billing. But Dark King: Forbidden Riches certainly leaves you on edge, with imposing (yet beautiful) graphics and an oppressive orchestral soundtrack that wouldn’t be amiss in Game of Thrones.

And just so you can see what we mean, TwinSpires Casino has made the Dark King: Forbidden Riches slot machine our Slot of the Week, meaning if you spend just $10 on the game, we’ll give you 20 free spins on the house.

It’s the ideal way to experience something new and possibly win big prizes for free.

How to Play Dark King: Forbidden Riches

In this five-reel, three-row slot, you are taken deep into the Dark King’s castle, where medieval-style graphics and fantasy, evil-looking symbols await. This is not some child-like attempt to be scary – the place is truly not for the faint-hearted.

The first thing to note is that NetEnt has done an awesome job with the production. The graphics are fantastic across all devices, and, as we mentioned, the soundtrack and sound effects are truly exceptional. The Dark King himself stands guard next to the reels – and he looks menacing, to say the least.

Happily, the game does not disappoint after such a promising opening. The base game is the usual state of affairs – match three or more symbols across one or more of the 20 paylines starting on reel 1. The lowest-paying symbols are the 10, J, Q, K, and A, beautifully drawn as if forged in metal by a skilled blacksmith.

Next are five figures in armor, with the Dark King himself being top of the pile. A blue orb represents a wild symbol, and this substitutes for all others, aside from the scatter symbol. On random occasions, the four golden face masks at the bottom of the screen come to life and award win multipliers to any wilds on the screen. If one happens to have made a winning line, your prize is multiplied 2x up to 5x.

This all makes for some top entertainment, but you want to keep playing until you get to launch the bonus round. Win lucrative free spins by landing three or more of the bonus scatters on any reel – these are the large, red jewels.

  • 3 scatters = 10 free spins
  • 4 scatters = 12 free spins
  • 5 scatters = 15 free spins

Trigger the feature, and the Dark King next to the reels comes to life, pulling his sword out of the stone. During the free spins, if you land a wild symbol on the highlighted cross shape on the reels, they become sticky for the remaining spins (each new wild also gives you one extra free spin). The wild multipliers also remain active in the bonus round – and the prizes can be significant.

The game has an RTP of 96.06%, which is just below average, and NetEnt describes it as high volatility, meaning you will likely experience big swings of wins and losses on different sessions. To be on the positive side, you really should hope to launch the free spins feature.

Who knows, if you opt into the Slot of the Week promotion and get our 20 free spins, you might get to trigger the lucrative game bonus for free.
