Book of Helios Slots

Helios, the Greek god of the sun, doesn't get much love in the online slots world. Betsoft is doing its part to change this, though, with Book of Helios slots. This 5-reel, 10-payline game follows an explorer named Olivia Brave, who enters the temple of Helios in search of priceless treasures-including a huge max win worth 20,168x your stake. If you're interested in joining Olivia Brave on this dangerous treasure-hunting expedition, then you can check out our Book of Helios slots review.

Gameplay

This game features 5 reels and 10 paylines going across a 5x3 grid. You earn payouts by getting 3 or more matching symbols in a payline. All wins have to start in the first reel, just like with most online slots.

Graphics and Theme

In typical Betsoft fashion, Book of Helios slots features high-quality graphics and an entertaining theme. You'll see two red-eyed horses, which carry Helios' chariot, on both sides of the reels. The Greek god himself overlooks the reels with a scowl and red glowing eyes. We imagine that Olivia Brave is doing everything possible to avoid Helios while looking for his sacred book.

Symbols, Payouts & Max Win

Regular symbols include five royals, a whip, crossbow, Olivia, and Helios. The god pays the most out of this group, delivering 20x the total bet for five matches. As covered before, you can win a whopping 20,168x your overall stake. The Book of Helios max win is one of the biggest in Betsoft's lengthy history.

Book of Helios Slots Features

Much like other "book of" slots, this game's main feature includes free spins with an expanding symbol. You trigger 10 free games by landing the Book of Helios (scatter & wild symbol) three times on the grid. The book can only land in reels 2, 3, and 4. Prior to free spins starting, one symbol is randomly chosen to be an expanding symbol and cover its respective reel (1x3). Here are additional rules on the bonus round:

• The selected symbol expands when it appears 2 or 3+ times on the reels and can help create a win.
• Expanding symbols don't have to be in adjacent reels, or start in reel 1, to deliver payouts. They can help provide wins from anywhere.
• Any Book of Helios wild symbol that lands on the grid will expand to cover its respective reel. It also provides a multiplier ranging from 1x from 5x, which applies to all wins that it helps form.
• Multipliers will multiply each other when appearing in the same win. For example, three 5x multipliers would provide a 125x multiplier (5x5x5x = 125).

This game also has a bonus buy option. You can buy 10 free spins at any point during base-game play for 65x your stake.

Betting Options

You can bet between $0.20 and $20 per spin. If you ever get tired of spinning the reels manually, autoplay is available. This option keeps the reels spinning automatically for 5 to 100 spins. Of course, you can turn autoplay off at any point before the spin counter runs out. Other options include the ability to turn sound and background music on or off.

Book of Helios RTP & Volatility

The Book of Helios RTP is 95.58%, which is about average compared to other online slots. We'd prefer to see the RTP at 96% or higher like some other Betsoft games, but we'll still take this figure. The volatility is high, which is to be expected considering the big 20,168x max win. Despite the high volatility, you will net frequent payouts thanks to the 35.03% hit rate.

Play for Free

You can try Book of Helios slots for free through demo mode. The free version is available via Betsoft's website and online casinos that carry this software developer's games. Playing the demo is never a bad idea because it provides an opportunity to test a game before risking money on it.

Verdict on Book of Helios Slots

We give Book of Helios a 9 out of 10 rating. Our team is impressed by this game's theme, graphics, bonus round, and max payout. Like usual, Betsoft has done an excellent job on making this slot visually appealing and entertaining. The only downside is the lack of base-game features because everything is loaded in the bonus. But you can always use the reasonably priced feature buy option (65x the stake) if you're tired of waiting on free spins. Overall, Book of Helios slots is definitely worth playing.
