Book of Secrets Slot Review

Share on

The game provider, SYNOT, takes you back to visit the ancient Pharaoh’s Tomb, hiding plenty of treasure.

How to play

The Book of Secrets slot uses a conventional playing structure with five reels and three rows. However, players have only 10 win lines to play on, outlines colorfully on either side of the grid. Fortunately, its interface is pretty clear and straightforward, thanks to the minimalist controls located below the reels. Before beginning to spin the reels, it’s wise to familiarise yourself with the gameplay first. As such, use the bottom leftmost three lines to open the help window, detailing the rules and paytable.

Here, punters can adjust their bet values anywhere between €0.20 to €100 per spin, using the “+” or ‘-” buttons adjacent to the bet display. Alternatively, clicking the “Max Bet” button will automatically set your stake per spin at maximum. Using the larger “Spin” button will allow you to start each game manually. Alternatively, use the “Auto-play” setting to choose up to an unlimited number of continuous spins according to your choices.

Symbols and payouts

You will encounter up to 10 thematic symbols as you gamble the Book of Secrets slot. You should try to match at least two or three of the same across a pay line to achieve a winning combination. However, the matching symbols should appear in consecutive positions from the leftmost reel to the right. Moreover, only the highest win per active line will payout.

The various symbols are in low-ranking and high-paying categories, depending on their payout rates. Like most other online slots in the industry, the playing card icons, tens to aces make the lowest-valued group. They will pay anywhere from 0.5x to 15x the total bet for three to five of a kind. The higher-ranking ones include different ancient artifacts — the Egyptian cross, a green scarab amulet, and the Pharaoh’s mask. Obtain two or more of each across a line to receive payouts worth 0.5x to 200x your stake. However, the most valued archeologist guarantees up to 500x the current wager for two or more.

A golden book of secrets acts as the scattered wild. As a scatter, it pays at any position on the screen, guaranteeing prizes worth up to 200x besides triggering the bonus mode. As a wild, it substitutes for all other icons except the special expanding symbol.

Best Book of Secrets bonus feature

There isn’t much activity happening around the bonus section. However, landing a lucky streak could see you receiving massive prizes! With that said, obtaining three or more scattered wilds anywhere on the reels will reward you with 10 bonus spins.

The game will then choose a random expanding symbol at the start of the free spins. During the mode, the special icons may replicate after all the regular wins payout to cover all the reel pockets. However, they will only expand when there are enough win symbols. Although the random icon pays like any other standard symbol, it doesn’t need to appear in adjacent positions to trigger a winning combination. When you land at least three more wilds during the round, 10 extra complimentary free spins will retrigger with the same expanding icon.

An optional gamble feature will activate after every base game wins except when using the Auto-play function. In this Book of Secrets bonus round, you need to predict correctly the next hidden card's color to double your gambled win. However, a wrong guess will cause you to lose the wagered win amount. Luckily, you can use the “Halve” option to play only half of the payout, with the rest credited to your bankroll. Further, the joker will substitute for any other color in this round.

RTP & Volatility

The theoretical average Book of Secrets RTP rate is set by the online casino and ranges between 88,38% and 97,94% However, spinners should take note of its high volatility and keep an eye on their playing account balance. Remember, high volatility translates to huge wins but with low hit frequency. So, a lucky streak, especially during the bonus mode, could potentially reward mega win amounts up to 1150x your bet!
