Book of Helios slot REVIEW

Book of Helios ReviewBetsoft 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 across 5 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 are well above average, which means that you can look forward to many well-designed symbols, sweet animations, and great visual effects.

Book of Helios Slot – Reels Screen

Book of Helios has a high volatility 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 at 35.03%, 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 is 95.58%, which is a bit below average.

Book of Helios Slot Features

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 naturally worth the most and 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 as both the game’s Wild and its Scatter. In other words, it can both complete winning combinations and trigger the Free Spins feature.

Book of Helios Slot – Free Spins Feature

To get to the 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 reveal a win multiplier of up to 5x that will boost your wins!

Players that don’t want to wait for Book symbols can also buy into the Free Spins feature by using the Buy Feature option. It’s available at all times, but it will set you back by 65.5x your stake.

Review Summary

Book of Helios is a rock-solid “Book of” slot that 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!
