Betsoft are one of the big players on the online slot gaming market, and a large chunk of that is because they are happy to work with US online casinos. That means that their games are available to US players, so we simply have to review every single one of them as soon as possible. With Book of Helios, we have another addition to the ever-growing “Book of” niche, with a classic payline setup as well. It all takes place across5 reels, 3 rows and 10 fixed paylines.
Thematically, Book of Helios is about a female adventurer that’s on a quest to get some riches in a temple dedicated to the mighty god Helios. The production values arewell above average, which means that you can look forward to many well-designed symbols, sweet animations, and great visual effects.
Book of Helios has ahighvolatility level, which means that you have to be ready for a swing every now and then. At the same time, the hit frequency clocks in at35.03%, which is rather solid and which means that you’ll get a win every third spin or so. The betting range seems to be geared mainly towards low rollers. The min bet is£0.10, while the most you can risk per spin is£10. That’s bound to disappoint some high rollers, but there you go. Finally, the theoretical RTP of Book of Helios is95.58%, which is a bit below average.
There are 9 pay symbols in Book of Helios, with 5 low pays and 4 high pays. The low pays show card ranks from Tens to Aces, with Aces paying up to 8x your stake for a full set of five matching symbols. The high pays, meanwhile, feature whips, crossbows, female adventurers, and the titular Helios himself. Helios is naturallyworth the mostand will net you a sweet 20x payout if you find him in a five-of-a-kind combination.
Since Book of Helios is a “Book of” slot, it won’t surprise you to learn that it has only one special symbol in its Book symbol. This symbol works asboth the game’s Wild and its Scatter. In other words, it can both complete winning combinations and trigger the Free Spins feature.
To get tothe Free Spins feature, you just have to find 3 Book symbols in a single spin. When that happens, you’ll get 10 free spins and one random pay symbol chosen as Expanding for the entire duration of the feature. Note that there are no retriggers on offer.
As per usual, Expanding symbols can expand to cover an entire reel and also pay out even when not fully adjacent. The twist that Book of Helios brings to the table is that you can get something out of Book symbols that land during free spins. These will always expand vertically and substitute for the given Expanding symbol. Even better, they will also reveala win multiplier of up to 5xthat will boost your wins!
Players that don’t want to wait for Book symbols can also buy into the Free Spins feature by usingthe Buy Feature option. It’s available at all times, but it will set you back by 65.5x your stake.
Book of Helios isa rock-solid “Book of” slotthat adds win multipliers to the classic gameplay formula for another boost. It’s thanks to this bit that the game can offer such a big jackpot and that you can win more than 20,000x your stake if you get lucky. And, since the slot is available to US players, it means that basically everyone can enjoy it!
