How to Play

Once you press past the Splash screen, you’ll enter the main game interface. It includes a standard game structure with five reels, three rows, and 10 fixed paylines. The line wins pay from the leftmost side to the right. A humongous reel set covers the entire screen and is bordered with a colorful outline of the win lines on both sides. Meanwhile, the control panels are located below the reels, making them easily accessible.

Use the Plus and Minus buttons to adjust the stake amounts from €0.10 to €20. From the betting range, this Book of Secrets Extra slot game should be ideal for low-betting players. The Max Bet button sets the game to the highest available stake. Click on the Spin button to play one game round on the selected bet. Or, use the Autoplay feature to gamble continuously up to infinity. The Menu icon expands a pop-up list displaying the paytable and help buttons.

Symbols and Payouts

The Book of Secrets Extra slot combines ten symbols into its paying lineup. If you’re curious about the symbol combinations and payouts, then consult the game’s paytable. If you match at least two or three identical symbols in consecutive positions and on active pay lines from the leftmost column, you’ll receive winning combos. But, scatter symbols pay at any on-screen position. All paying combination sequence prizes are multiplicable to the total bet.

The lowest wins originate from the 10, J, Q, K, and A card royals. If you hit at least three of the same, you’ll receive between 0.5x to 15x your stake. Then, two or more of the Ankh, Scarab, Pharoah, and Explorer images will give out the high wins worth 0.5x to 500x the selected bet.

The Book acts as a scatter wild, which can pay between 2x and 200x the stake when 3+ land anywhere on the screen. As a scatter, it’ll trigger the free spins, while as a wild, it’ll substitute for all symbols except the special card. Continue reading onto the next Book of Secrets Extra slot review for the bonus details.

Best Book of Secrets Extra Bonus Feature

The bonus section is quite shallow, which explains the low maximum win of a 500x bet. However, you’ll certainly appreciate the available features once they hit since they’ll improve thrill and your bankroll balance.

First, is the Book of Secrets Extra free spins round which triggers when you gather three or more Book scatters. The game starts with 10 bonus plays and a special expanding symbol. During the games and after payment of the regular wins, the extending icon may expand to cover an entire column. The expansion happens only if there are enough symbols to trigger a win. The free spins are re-triggerable with a new special symbol randomly selected from the remaining icons.

Players can gamble any payout that doesn’t exceed €125,000. The card-based gamble feature gives participants a chance to guess the color of the next revealed card. While a correct guess doubles the gambled win, a wrong one will cause you to lose the amount. You can opt for the HALVE option to reduce the risk exposure and you're allowed to gamble up to 10 times per single gamble feature.

Willing players can buy 10 Book of Secrets Extra bonus games at 100x bet using the Buy Bonus feature in the base game. The betting range widens to €200 when this feature is active.
