Book of Books: volatility, RTP and your real chances to win

Book of Books is a highly volatile video slot built around expanding symbols, enhanced free spins, and a power-ups system. The game has a fantasy-mystical theme and is aimed at players who prefer rare but potentially large wins.

The slot uses a certified random number generator, and the theoretical return to player (RTP) percentage is 96.1%, which meets modern standards for fair online casinos. The results of the spins do not depend on the player's strategy and are generated randomly.

Book of Books is available on PCs, smartphones, and tablets, runs in a browser, and does not require the installation of additional software.

Book of Books bonus features

Free spins

Free spins are activated when 3, 4, or 5 Scatter symbols appear and are played at the same bet as the spin activator.

Free spin parameters:

• 3 Scatters — 5×3 field, 10 lines
• 4 Scatters — 5×4 field, 20 lines
• 5 Scatters — 5×5 field, 40 lines

The player receives 7 free spins + all collected power-ups. At the beginning of each free spin, active expanding symbols are selected at random.

Power-ups

When 2 Scatters appear, the player receives one of the following power-ups:

• 1 or 2 additional free spins
• an additional expanding symbol
• x1 or x2 multiplier for expanding symbols

All multipliers are added together, increasing the potential winnings.

Expanding symbols

If an expanding symbol is part of a winning combination, it expands to cover the entire reel, resulting in an additional payout. These symbols are paid out on 10 lines, regardless of the size of the field.

Golden Bet

The Golden Bet feature allows you to increase your bet by 1.5 times, significantly increasing the likelihood of triggering the bonus game. This is a useful tool for players who bet on the bonus potential of the slot.

Buy Free Spins

Players can buy free spins directly by selecting the bet size.

• RTP when buying a bonus: 96.2%
• Maximum bet per spin: $6,000

The number of Scatters when purchasing (3–5) does not affect the RTP — it remains the same.
