Payouts are counted from left to right on a payline. Matches must be like symbols, or like symbols and the wild for wins.

Wild Symbol

The book symbol is a wild. It will substitute for any other game symbols to help you gain match wins on paylines. As most slot players know the wild symbol can certainly be helpful in many games.

Book of Helios is Scatter

The book is also the scatter symbol and appears on reels #2, #3 and #4. Any time. you get 3 of them anywhere on the board, you will win 10 free spins.

Special Symbol Chosen

At the beginning of the free spin rounds, 1 regular symbol is chosen as he special expanding symbol. Any time during the round when you get the special symbol on 2+ or 3 + reels and can form a win they expand. Each one will expand to fill the reel and increases the wins like they were regular symbols.

In addition if you land any book symbols they also will expand to increase the wins as wilds. This will reveal a multiplier which can lead to large wins during the round.

Additional free spin rounds will not be awarded during the free spins.

Wild Multipliers Multiply Wilds

The wild multiplier symbols will multiple additional multipliers during te free spin round, As an example, if you get 3 5X multipliers, it would be 5x times 5x times 5X for a 125x multiplier.

Buy Free Spins

One thing some players like about this game is the ability to buy free spins. If you are impatient and want to buy the free spin round, you can buy them. Amount spent on free spins is dependent on the spin bet and is clearly identified on the shopping cart symbol during the regular game. The free spin purchase will award 10 free spins.

Bet Limits

With 10 fixed lines this slot can support even the most conservative budget conscious players. You can bet from $0.01 per line up to $2,99 per line. This allows bet ranges from $9.19 uo to $20.00 per spin.

High Volatility

This game does have a high volatility. Even so it is listed at an average rtp of 95.58%. While we think the rtp is within the acceptable range we usually bet a bit more conservatively on the slots with high volatility, but this has paid off for us quite often.

Conclusion on the Slot

While we are not huge fans of the buy feature many players do in fact like it, so having the option n some games is good. We like the story behind the game theme and had some fun helping Olivia find the books. The expanding special symbols and expanding wilds during free spins helped our win amounts frequently.

After speaking with a few operators that have this game they have the game ranked highly for regular return visitors. This is based on games players choose to play often. When players return to play a game often it usually means it is meeting or exceeding the rtp frequently, so this is a game not to be overlooked.
