The impressive graphics showcase the studio's unique visual style and character design. Players will be in awe of the game's aesthetics, reminiscent of some of the studio's earlier work, such as Johnan Legendarian and Robin Sherwood Marauders.

RTP and Volatility

According to Yggdrasil, Book of Books is a high-volatility video slot with an RTP of 96.1%, which is standard for these games. The hit frequency is 33.26%. However, players should note that lower RTP models are also available.

The high volatility of Book of Books means that players may experience long periods without winning, but when a win does occur, it is likely to be more significant. This can make the game particularly exciting for those who enjoy the thrill of chasing big payouts. However, players should also be aware that the high volatility nature of the game can make it more challenging to maintain a healthy balance, and budgeting appropriately is recommended to ensure a positive gaming experience.

The hit frequency of 33.26% indicates that, on average, players can expect to hit a winning combination on roughly one in three spins, which can provide a sense of regularity and keep the game engaging for extended sessions.

The main game has a 5x3 panel with 10 Paylines evaluated from left to right. Wilds substitute for any other symbol except the Scatter. Scatters do not pay.

• 2 scatters award a power-up.
• 3 or more scatters trigger the free spins game.

Landing 2 Scatters award any of the following features that are added to your free spins session:

• 1 or 2 additional free spins.

Free spins are triggered when 3, 4, or 5 scatters land into the panel. Free spins are played with the same bet as the activating spin.

The free spins game is played with all collected power-ups. Seven free spins are awarded, plus any extra free spin powerups are collected. Powerups are reset when the free spin session ends.

When a regular win is calculated, if there are expanding symbols in the panel, these expand to cover the whole reel where they are located, and an additional prize is awarded. At the beginning of each free spin, the active expanding symbols are randomly selected. Expanding symbols can not be substituted by Wilds, and they pay even on non-adjacent positions. Expanding symbols pay at ten paylines independent of panel size.

Free spins can be retriggered, two or more Scatters award extra free spins, powerups, and panel resize as follows:

• 2 Scatters awards, one free spin, and one random power-up.

• 4 Scatters award five free spins, one random power up, and resizes the panel to 5x4.
• 5 Scatters award seven free spins, one random power up, and resizes the panel to 5x5.

The number of free spins is displayed in the top left counter, the multiplier applied to the expanding symbols is shown in the top right counter, and the current spin expanding symbols are displayed under the panel.

Conclusion

Numerous "book slots" are released each year that adhere to the traditional recipe, leaving little room for experimentation. However, Peter & Sons has created an innovative and enjoyable addition to the popular genre with the Book of Books. The forest backdrop is refreshing, and the medieval characters playing music around the grid add to the appeal. While the title implies that this is the "ultimate" book slot, its eccentricity makes it unlikely to surpass the top-tier titles.

Devotees of traditional "book slots" may disapprove of Peter & Sons' artistic liberties, but others will appreciate the innovation. The power-up system adds an element of unpredictability, particularly when combined with the various expanding symbols. This is one of the few "book slots" in which trigger the bonus round as soon as possible is undesirable. The longer you play, the more rewarding it becomes, and we experienced numerous expanding scatter wins during our testing session. Although Book of Books may not suit everyone's preferences, we will undoubtedly return to play it again.
