The Book of Helios slot machine from Betsoft has a big prize of 20,168 times your bet in its usual 5x3 reel, 10 payline setup. The recently released video slot game, which includes Helios, the Sun God, and one of the Titans, is inspired by Greek mythology.
The game's main character is a female warrior named Olivia Brave who wants to raid the sun god's temple and take tonnes of loot. Another legendary symbol that appears on the reels and functions as both the Wild and the Scatter is the actual "book" of Helios, in line with the game's name. The wild can replace any regular symbol on the reels to produce new winning combos.
Additional high-paying standard symbols include the Whip, Crossbow, Helios, and Olivia symbols. A, K, Q, J, and 10 are playing card symbols that appear on the reels and are also lesser paying.
Landing three or more Book Scatter symbols will trigger the Free Spins phase, which awards players 10x the number of free spins. During the Free Spins phase, a randomly selected symbol that can expand over the reels and create new winning combinations is chosen. If the symbol appears on two or more reels simultaneously, a win is awarded, and it expands vertically across all reels. This unique symbol goes above and beyond the regular victories, boosting the game's thrills and prizes. If a second Book symbol appears while the bonus game is still active, it will also expand to fill the reel and add multipliers of 1x, 2x, 3x, 4x, or 5x.
Despite not being the most lucrative of all video slots, Book of Helios is a delightful experience for players of all budgets with a betting range of 0.10 to 10, maximum possible wins of 20,168x, and an RTP of 95.58 percent.

The Book of Helios slot game by Betsoft follows the traditional 5x3 reel format with 10 paylines, and comes with a lucrative jackpot of 20,168x your bet. The recently released video slot game is based on Greek mythology, with Helios being the Sun God and one of the Titans. Helios can be seen in the game on his fiery chariot and stony horses, riding his way to victory.
Central to the game is a female warrior called Olivia Brave, who wants to infiltrate the temple of the sun god and carry away loads of riches with her. The reels have other symbols right from the pages of mythology in the form of the physical ‘book’ of Helios in keeping with the game title, which acts as both the Wild and the Scatter. The Wild can replace any regular symbols on the reels to form new winning combinations.
Other high-paying regular symbols include the Whip, Crossbow, Helios and Olivia symbols. Landing any two of these high-paying symbols can lead to a win. Landing 5 identical symbols, however, on a single payline will give you between 10x to 20x your stake. Lower paying symbols can also be found on the reels in the form of playing card icons A, K, Q, J, and 10.
Landing at least 3 Book Scatter symbols triggers the Free Spins round, offering players 10x Free Spins. During the Free Spins round, a symbol gets randomly selected that can expand across the reels and create new winning combinations.
If the symbol appears on 2 or more reels simultaneously for a win, each expands vertically across the full reel. This special symbol kicks into overdrive beyond the regular wins, making the game even more exciting and rewarding. Another factor to note is that while the special symbols pay like regular symbols, they do not need to land on any payline for a win. Should another Book symbol land during the feature game, it will also expand to cover an entire reel to add Multipliers to the tune of 1x, 2x, 3x, 4x, or 5x, calculated for the full reel and not for each symbol.
Conversely, if you do not want to wait around for the Free Spins to come to you, you may even buy the feature instantly using 65.5x of your stake for 10 Free Spins. The Scatter symbol lands only on reels 2, 3, and 4. Free Spins cannot be re-triggered. With a betting range from 0.10 to 10, potential maximum wins of 20,168x, and RTP of 95.58%, Book of Helios may not be the most rewarding of all video slots but is certainly an entertaining ride made for all pocket sizes.
