Book of Power Slot Machine

Book of Power from Relax Gaming is a volatile 'book mechanic' slot with 5x3 reels and 10 paylines. The standard bonus round includes retriggers that grant additional expanding symbols or upgrade existing expanding symbols with multipliers. In the Power Spins feature, the special symbol is promoted tier by tier with each retrigger, and the multiplier increases with each retrigger once you reach the Explorer symbol. The maximum gain is 15,000 times your bet.

Slot Features

For 5 of a kind winners, the premium symbols, with the Explorer as the highest-paying symbol, pay between 75 and 500 times the wager. The low-paying royals pay between 10 and 15 times your wager, and this game features two Book symbols (the standard Book and the Power Book). Both book symbols serve as substitutes for pay symbols to help complete winning combinations, and they also serve as dispersion symbols.

You receive 10, 15, or 20 free spins when 3, 4, or 5 Book scatter symbols appear anywhere in view, as well as a payout of 10, 100, or 500 times your wager. The book opens to reveal the special expanding symbol before the feature begins, and this symbol expands to create full line wins if you strike enough instances anywhere in view after the initial win.

In other words, the special symbol does not need to appear on adjacent reels to expand and pay. Obtain an additional expanding symbol and +5 additional free spins if you land two Book scatters during the same free spin. If the new special symbol is already active, its multiplier is increased by 1. Since only eight retriggers per feature are feasible, the maximum multiplier is 9.

The Power Bonus Round is triggered if one of the triggering Book symbols is the Power Book, which also awards 10, 15, or 20 Power Free Spins with an initial scatter win of 10, 100, or 500 times your wager, respectively. Again, a random pay symbol is chosen at random to serve as the special expanding symbol, and it operates as described previously.

The significant difference is that the expanding symbol is upgraded when two Book scatters appear during the same free spin, which also awards an additional five free spins. Additional retriggers will add +1 to the symbol's multiplier, up to a maximum of x9, if you succeed to upgrade the special expanding symbol to the top-tier Explorer. When the Power Book appears on reels 2, 3, or 4, the reel is upgraded to gold. Even if a special symbol does not appear on a golden reel, it counts as the expanding symbol.
