Betsoft Book of Helios Mythology Slot

Book of Helios is a slot machine from Betsoft which immerses us in the mythological confrontation between the legendary god of the sun and the heroic explorer Olivia Brave who has come to challenge him in his temple to recover a precious artifact: his magic book!

The god then appears to him on his chariot, ready to do battle. The two warriors, as well as their weapons: the bow for Helios and the whip for Olivia, are represented on the machine’s big win symbols.

This slot is a one-armed bandit with a size of 5 by 3 which has 10 paylines. The maximum bet on this casino game is 10 euros, which is quite low compared to other slot machines but you can still win more than 20,000 times this amount, good winnings with reasonable bets!

A bonus based on free spins

The Book of Helios is the central element of the bonuses of this game. It is both the WILD symbol, which allows you to replace a symbol to make a winning combination, and the Scatter, which if you bring together 3 at the same time screen, will give you 10 free spins.

At the start of these free spins a machine symbol will be selected at random to become an Expanding Symbol. If this symbol appears on 3 or more reels, it will cover the entire reel. This also applies to WILDs.

And these Expanding symbols bring you wins even if they are not next to each other. This bonus is the only one in Book of Helios but it is not window dressing, it is very effective and guarantees you interesting winnings.

Our opinion: A machine that gets to the point

Book of Helios is a pretty cool casino game. This machine exploits a theme that always works, Greek mythology and offers a simple Bonus based on free spins, which players always appreciate.

This bonus has a very good return rate which makes it a good slot for those looking to get reasonable winnings often rather than a big jackpot more rarely.
