Kingdom of the Dead is a collaborative effort from the teams at Reel Kingdom and Pragmatic Play. The two names have worked together in the past to create the popular Big Bass Bonanza slot series, and they are hoping they will have another hit on their hands with the ancient Egyptian-themed Kingdom of the Dead. Any long-time slot player will instantly have their suspicions that this title may be one from a long line of "Book of..." real cash slots, and they’d be correct. Is putting a slightly different spin on the name the only thing this slot does? Let’s take it for a spin in this Kingdom of the Dead slot review. 

Slot graphics have come a long way since Egyptian-themed games like Book of Ra and Cleopatra. Pragmatic Play has designed a really well-polished game with Kingdom of the Dead. The reels stand out in the middle of the screen, bordered by glittering gold and jewels. The symbols on the reels will be familiar to anyone that has played an Egyptian-themed title before, with a handsome adventurer making an appearance alongside a selection of Egyptian artifacts depicting various gods. The soundtrack is generic but inoffensive and is not going to make you want to reach for the mute button.

Pragmatic Play develops all of its slots using HTML5 technology. You can take the slot for a spin on both your smartphone and tablet, with the game supported on Android and iOS operating systems. Most top online casinos will now offer mobile play options, with some having mobile slot apps available.

Kingdom of the Dead isn’t trying to do anything too complex with its base game. The slot uses a standard 5x3 set-up, which you can expect to find in most top free slots online. There are 10 paylines that are active in every spin, with wins being formed of three or more matching symbols starting on the leftmost reel. 

You can adjust the stake by clicking on the +/- buttons on either side of the spin button. You will also find the autoplay option here. The game’s minimum stake is $0.10, and the maximum is $250.

The "Book of..." games mechanic is all about expanding symbols, and Kingdom of the Dead sticks with that while adding a bit of a twist.

Firstly, you will need to trigger the Free Spins Round. This is done by landing three or more of the Scatter Symbols, which, fittingly, is a book. Players will get given ten spins. They will then be given a choice of two bonuses.

They can either play the round with a standard Expanding Symbol, or they can play it with a Mystery Expanding Symbol. If they opt for the standard route, a symbol will be chosen at the start of the spins that will expand whenever it lands. If they go for the mystery option, the symbol will change on every spin.

During the round, if players land three more Scatter Symbols, they will be granted an additional 10 spins. There is no limit on the number of spins you can have.

The game also has an Ante Bet feature. This allows players to increase their stake by 50% for an increased chance of triggering the Kingdom of the Dead Free Spins.

The Kingdom of the Dead slot game has a solid maths model. The game has a maximum win of 10,000x the player’s stake, which is a good offering for a "Book of..." slot. It is considered highly volatile and has an RTP of 96.07%. This puts it around the industry average. A handful of versions are also available with smaller RTPs, so go to the paytable and check before you hit the Spin button.

At this stage, the selection of "Book of..." slots on the market is pretty expansive, so finding something new to do with them is tricky. The addition of a Mystery Expanding Symbol might not be the most creative, but it does add a little bit of a twist to the game and helps it stand out. The 10,000x maximum win is also going to be a selling point, and the slot looks much sharper than many other Egyptian-themed titles found at the best slots sites. If you are a fan of these gameplay mechanics, then Kingdom of the Dead is a title well worth adding to your list. If you want something fresh, it might not be the game for you.
