Dark King: Forbidden Riches Slot Review

Dark King Forbidden Riches slot was launched in early 2021 by Netent and features a dark fantasy theme. It's loaded with spooky and eerie visuals (but great HD graphics none the less) and a perfectly fitting orchestral soundtrack.

Whilst it may sound dark, it's immensely entertaining. In our Dark King Forbidden Riches slot review, our slots experts have uncovered everything you need to know about it. From exciting in-game features, max win potential, RTP %, variance and more. No stone is left unturned so that you can understand what to expect if you play this game, or help you make up your mind if this slot could be a game for you or not.

Slot Game Design & Set-Up

All of the action happens on a 5×3 reel and a 20 payline set up. Bet levels range from 20p to £200 per spin. Graphically, this slot looks amazing, even though it is dark and somewhat moody. The setting takes place in a chamber in the Dark King’s castle. The reels are flanked by skulls and a Knight in a suit of armour. The reels are made up of medieval-styled A to 10 typography symbols, as well as 5 higher-paying skeleton warriors, orbs and the faceless Dark King himself (we told you this was a menacing slot!).

Dark King: Forbidden Riches RTP %, Variance & How To Win

This slot game is considered to be a medium to high variance slot. This means that it should be suitable for most types of players, with medium-sized wins coming in fairly often. The Dark King: Forbidden Riches RTP is 96.06%, which is a rather average theoretical return to player, especially for Netent slots.

The biggest payout per spin is 500 x your total stake, however, if you mix in the multipliers we mentioned above, then you can reach an x5 max win, which will payout x2,500 your stake on each spin. The ominous faceless Dark King is the most rewarding symbol in the game. He will award you 1, 7.5 or 25 x your total stake if you land 3, 4 or 5 on an active payline. What's more, you can also achieve the same high payouts if you land the blu orb too, which will also replace all symbols except for the Scatter symbol.

Dark King Slot Features

To say this game is a little busy is an understatement. However, this is how Netent likes to do things. The main features within Dark King Forbidden Riches Slot include Free Spins and extra Free Spins) Scatters, Multiplier Wilds, Sticky Wild Hotspots and Sticky Wilds:


The shimmering crystal orb works as a Wild symbol in the Dark King: Forbidden Riches slot. The Wild's main job is to substitute all symbols except for the Scatters. Also, they will activate the game’s Wild Multiplier feature, which will give multiplier up to 5x for 5 orbs. The four different multipliers: 2x, 3x, 4x and 5x lurk behind golden faces below the reels and stay active during both the base game and the free spins feature.


The Scatter symbols are represented by the red gemstones which are encased within a gold frame. The Scatters are your way into the Free Spins feature in this game. You’ll trigger the Free Spins features by landing 3 or more Scatters in view anywhere on the reels. Once 3 or more Scatters form on the reels, they will accumulate in the Dark King’s sword, which he will use to strike the ground to open up the Free Spins game!

Free Spins

Probably the round that we will all be waiting for - the fantastic and exciting Dark King Forbidden Treasure Free Spins game. It's the highlight of the slot, hands down. As mentioned briefly above, when you land 3 or more red gemstones (Scatter symbols) on the same spin and you’ll activate the Free Spins feature:

Here, the Wild symbols are once again the answer to victory in this feature, just like they are during the base game. Throughout the Free spins game, you will see a set of symbols on reels 2, 3 and 4 which are highlighted in the shape of a Cross. This is called the "Hotspot Zone".

HotSpot Zone: Get a Wild to land in the Hotspot Zone, and it'll turn into a Sticky Wild, which will then turn that Wild for the remainder of the Free Spins feature. What's more, each sticky Wild that hits gold will also add one more free spin to your balance. Furthermore, Wild multipliers are active during the Free Spins as well. Here, there are some great opportunities to get some multipliers moving you forward for bigger wins, particularly if you manage to land a couple of Wild symbols early on in the run-up.
