Tom Horn Gaming has introduced what we feel is one of the more interesting slot games of this new season, and it goes by the title “Book of Darius”. Book of Darius is clearly inspired by Aladdin and has a distinctive Middle Eastern fantasy/magical theme that many players seem to love. It offers 9 fixed paylines, so you don’t have to bother with adjusting paylines for every spin since they are always fixed. This makes playing this game simple and easy. One of the biggest highlights of this game is something called the shatter mode, and we will talk more about this mode and why it is so exciting later on this page. In order to curate this review for our South African readers, we’ve played this game for weeks on end and tested every aspect of it rigorously. So, you don’t have to learn the ropes yourself, and you can just get to playing like a pro right from your first spin! On this page, we’ll discuss how you can play this game properly, how the various features of the game work and even answer some FAQs about the game to make everything crystal clear for you.

When you first open Book of Darius, you’re going to be welcomed by an Arabian-inspired cityscape that is very reminiscent of Aladdin (Disney). The Middle Eastern backdrop is both magical and dreamy. The reels take up the centre of the screen, and the sides are mostly just the blurry backdrop of the desert cityscape. You’ll see a magic lamp with a bright purple background, curved swords with gold hilts and two central characters that are knockoffs of Aladdin and Jasmine. A domed palace can be seen in the upper part of the screen, where you’ll also see the four multiplier icons labelled 1x, 2x, 3x and 4x.
The bottom panel features the main controls for adjusting bets. It also shows your total credits on the left, with the bet value on the right. The game’s menu icons are easy to spot beneath the reels, and so the game is pretty easy to operate, even for newbies.
Free Games: Free games are a staple in most modern online slots, and Book of Darius is no exception. You will get 10 free spins whenever 3 Book symbols appear on reels 1, 3 and 5 at the same time. Whenever you make it into the free spins round, you’ll see a quick little animation that shows you which icon will play the role of your special expanding symbol. The special expanding symbol in free spins will take up the entire reels if it’s part of a winning combo. The positioning doesn’t have to be on the consecutive reels or anything. For example, if the chosen symbol lands on reels 2 and 5 and it qualifies for a payout, it can expand on both reels. That can produce a nice stack of identical icons, and if you combine this with the multiplier that arises from the shatter chain, things can get interesting in a good way. Free spins can be retriggered if you again land 3 Book symbols, and when this happens, you will get 10 more free spins.
Shatter Mode: Shatter mode is probably the biggest highlight of this game called Book of Darius. Whenever you form a winning line in either the base game or during free spins, the involved symbols burst and go away. New symbols come in from above to fill the gaps. If these new symbols form another winning line, then you get an increased multiplier, and the chain continues in this way. The multiplier steps up with every consecutive win, but it gets capped at 4x. This single feature has the ability to chain multiple wins from a single spin, and the excitement shall really build when you hit 2x or 3x and are waiting to see if you can escalate it further before the chain ends. Since you can trigger free spins within shatter mode, it sometimes feels like the game is handing you a second chance. If you initially land 2 book symbols, then the third book appears after the previous symbols vanish.
With a theoretical return to player (RTP) of around 95%, Book of Darius is basically in an average spot compared to online video slots by other providers and also by Tom Horn Gaming. This RTP is a theoretical number, and it basically means that for every R100 wagered on this game, the game will payout R95 to players over the course of time. This does not mean that you will always get back R95 if you wager R100; you could get much more or even less.
We spent quite a bit of time putting the Book of Darius through its paces. The game did not have any dull moments because even base spins can give rise to multiple-win combos, and once you finally trigger the free spins, the excitement is really turned up to the max. The shatter mode is a game changer and a very exciting new feature which felt like a breath of fresh air. The game also works for players on a budget as well as players who like to splurge big. Tom Horn Gaming is a respected game provider, and you don’t have to worry about the quality of the gameplay or about facing any glitches or technical issues when playing, as long as you have a stable internet connection. The Aladdin-inspired theme is also nicely implemented and gives you a dreamy and magical feel. Although the background music complements the theme, it can start to get on your nerves after a while, and so it is great that you have the option to mute the sound with just a single click.
You get 10 free spins when you land 3 Book symbols on reels 1, 3 and 5 in the same spin sequence. This comes down to luck, and there is nothing specific that you can do to get this combination. The more you play, the more likely you will come across this combo and get your free spins!
Shatter mode comes into play whenever you form at least one winning line in the base game or in free spins. The winning icons shall explode and leave behind empty spaces so that new ones can fall from above. If another win forms, the multiplier steps up, and this can go on until no new line pays or you reach 4x.
No. During free spins, if your chosen special symbol appears in an arrangement that forms a valid payout, it will expand on the reels where it landed. It does not have to be on adjacent reels to be counted as a winning line.
Gambling can be addictive, please play responsibly.
