Book of Power

Book of Power Slot Overview: Is It Worth Playing?

Book of Power is Relax Gaming’s very high volatility take on the classic Egyptian book slot, built for players who want serious bonus features and real max win potential. The 5-reel, 10-payline setup feels familiar, but the added Power Bet, Lucky Boost, and dual free spins modes give this slot far more depth than a standard book game.

If you enjoy chasing big expanding symbol hits and do not mind stretches without a feature, Book of Power is aimed directly at you. The default 96.11% RTP, 15,000x max win, and strong bonus focus make it a clear pick for bonus hunters and stream-style sessions.

How the Gameplay Works

Book of Power runs on a simple 5x3 grid with 10 fixed paylines, so learning how to play Book of Power is quick. Wins pay left to right on matching symbols, and the Book symbol acts as both wild and scatter. You spin, line up symbols, and wait for those books to land in groups of three or more.

The math is firmly very high volatility. Base game hits can feel light, often in the 0.2x to 5x band, with the occasional stronger line to keep things afloat. The real power sits in the free spins, where expanding symbols can cover full reels and pay on all lines at once.

Power Bet is the key pacing tool. Turn it on and your stake doubles, but the chance of triggering free spins jumps by about 170 percent, and RTP nudges up to around 96.50 percent. That shifts the session from slow grind to more frequent feature shots, at the cost of a faster moving balance.

How to Trigger the Book of Power Bonus Features

• Books: The Book symbol is both wild and scatter. Land 3, 4, or 5 Books anywhere on the reels to trigger 10, 15, or 20 Regular Free Spins. In the base game it also substitutes for all regular symbols, helping you connect line wins while you wait for that all important third book.
• Expanding Symbols: When Regular Free Spins or Power Free Spins start, one symbol is chosen to become special. Whenever enough of that symbol land to form a win, they expand to fill their reels and pay as if they covered all 10 paylines. This is where the slot’s best hits come from, especially when you retrigger and build up that symbol’s power.
• Power Bet: You can toggle Power Bet before spinning. It doubles your current stake on every spin but boosts the chance of triggering any free spins mode by roughly 170 percent and slightly improves the Book of Power RTP. If you hate waiting hundreds of spins for a bonus, this feature is made for you.
• Lucky Boost: Lucky Boost is a random modifier that can kick in when a free spins round starts. You do not control it, but when it appears it improves the round’s winning potential, often by making it easier for the expanding symbol to land in useful spots. It turns an average bonus into something that can surprise you.
• Bonus Buy Options: If your jurisdiction allows it, Book of Power gives you two bonus buys. Pay 100x bet to buy Regular Free Spins, or 200x bet to jump straight into Power Free Spins. Both buys use the same mechanics as natural triggers, but you skip the base game and go straight to the main event.

Book of Power Max Win and Payouts

The Book of Power max win is 15,000x your stake, which is serious for a 10-line book slot. Reaching it will need full screen expansions of top symbols, usually through a strong Power Free Spins round, but the ceiling is there for players who want big game potential.

The base game is more of a bridge to the bonus. You will see regular small hits and the odd medium win, but the slot is clearly tuned so that expanding symbols in free spins carry the real payout weight. If you are spinning without Power Bet, expect longer gaps between features, though the Bonus Buy options give impatient players a direct route to the action.

Graphics, Sound, and Mobile Experience

Visually, Book of Power is one of Relax Gaming’s stronger Egyptian releases. The reels sit in a detailed tomb scene, with sharp symbol art and clean animations when books land or symbols expand. The expanding sequences are quick and satisfying, which matters when you see them often in a good bonus.

The soundtrack leans into tense, mystical Egyptian themes, with heavier stings when you hit free spins or land expansions. It supports that very high volatility feel without getting in the way. On mobile, the HTML5 build runs smoothly on both phones and tablets. Controls are large and clear, and the 5x3 grid fits well in portrait or landscape, so Book of Power plays very well in short mobile sessions.

Final Verdict: Should You Play Book of Power?

Book of Power is a strong pick if you like book slots but want more control and more ceiling. The Power Bet and dual free spins modes give you real decisions about risk and pacing, and the 15,000x max win keeps the long term goal interesting.

If you prefer low volatility, steady small wins, this will feel too swingy. For players who enjoy chasing big bonus rounds and do not mind dry spells, Book of Power is one of Relax Gaming’s better very high volatility options and worth a serious look.
