Thunder kick chose a somewhat original theme for their first slot in the tradition of the book series, and Sword of Khans offers a very clever twist that makes this the most rewarding book series slot. Gone is the standard 5,000 x potential, where you can win up to 10,000 times your bet amount. For this developer, RTP is unusually low and takes hours at a rate of 95.36%. The fact that it’s slightly below the industry average shouldn’t be enough to scare anyone away from this excellent addition to the book slot series.
The main attraction, as always, is free spins with expanding symbols, as in this series. And for some reason we say symbols in the plural form, because in Sword of Khans Slot you can get more than 1 selected expansion symbol at the same time. The big twist (drumrolls) is the addition of a possible multiplier value of up to 3x to the selected symbol. This is the secret to enormous potential and there are huge gains here.
Therefore, you must have at least 3 sword scatter symbols to trigger the free rotation feature in the sword of Khans slot. First, you get a gain of 2x, 20x or 200x depending on how many you scatter, and then a random number of Free Spins (5, 7, 8, 9, 10, 12 or 15).
If you make at least 2 distributions in the same free spin, a random number of extra spins are added to your count. As you’re used to from other book series, there’s a special symbol chosen before the free spins begin, and this becomes the expanding symbol that fills every reel when it lands on the ground. What makes this game out of all similar games is that bringing back the free rotation feature gives you multiple selected, expanding symbols at once. There are other book series slots that do this, however, though none come with a phased multiplier. This is Thunderkick’s unique contribution to the series and a good one. When a symbol that is already a special symbol is selected, you get up to 3 times the multiplier instead. This means that every time you download that particular symbol, it will expand and carry a multiplier value of up to 3x. As you can imagine, if you get enough expanding symbols, you can do wonders for your payments.
