Book Of Cats links a random symbol selection in the main game to the special behavior of its Free Spins. One symbol is selected in the sixth cell, then acts as the Expanding symbol in the bonus, occupying three positions on a reel. Three or more Golden Book Scatter symbols start ten Free Spins with a random Expanding symbol; three or more Scatters during the bonus can award additional spins. This gives the feature a simple premise with a specific selection point and expansion size.

A selected symbol becomes the bonus feature
The official listing gives Book Of Cats 10 lines. The Golden Book serves as both Scatter and Wild, and three or more Scatters in the main game trigger Free Spins with a random Expanding symbol. The description also says one symbol is randomly selected in the sixth cell during the main game and plays the Expanding role in Free Spins. During the bonus, that special symbol expands across three positions on a reel. The available rules do not explain whether the sixth-cell selection is made on every main-game spin, how it relates to the later bonus selection, or whether the same symbol is selected twice. These descriptions establish the feature’s parts but leave their exact sequence unclear.
Three or more Scatters during Free Spins can award additional spins. The number awarded is not stated in the observed feature text. A Buy Bonus option can trigger the Free Spins round at a price pictured on its button, but no fixed price is given. The game also offers a Gamble after any main-game win: guessing a card’s color or suit aims to double the win. The source does not provide odds or explain the incorrect-guess result. These options concern entry and post-win risk; neither changes the stated three-position expansion rule.
The sixth-cell detail and feature scope
The sixth-cell selection is an unusual piece of the rules, but its timing is not fully spelled out. One description says it happens in the main game and becomes the Expanding symbol in Free Spins; another says the bonus begins with a random Expanding symbol. Those statements could describe the same selection carried into the bonus, or separate descriptions of how the selected symbol is determined. Because the source does not resolve that relation, the review should preserve both statements without inventing a mechanism.
Very high volatility is listed, alongside a maximum win of €246,060 and maximum multiplier ×8,202. These are overall game values, not feature-specific limits. The observed description gives the expansion width and Scatter threshold, but not a cap on retriggers, their spin award, or how the maximum values are reached. The volatility label cannot answer those mechanics questions.
Published settings
BGaming lists 96.99% RTP, Very high volatility, 10 lines, maximum win €246,060 and maximum multiplier ×8,202. The amounts use different units and remain separate. Release date is July 8, 2020.

Strengths and weak points
Strengths
The selected-symbol concept has concrete boundaries: selection is associated with the sixth cell, three Scatters start ten spins, and the chosen bonus symbol expands across three positions.
Weaknesses
The source does not reconcile sixth-cell selection with the random bonus symbol, or state retrigger awards and Gamble odds, leaving important feature timing and value uncertain.
Our Editor’s View
Book Of Cats has a distinctive central idea: a symbol selected in the main game becomes the expanding symbol in Free Spins, where it covers three reel positions. The Golden Book supplies both Scatter and Wild roles, and the ten-spin trigger is clear. What is less clear is how the sixth-cell selection relates to the random symbol named for the bonus; the observed descriptions do not establish whether that is one carried-over choice or two separate selections. Retrigger spin awards and Gamble outcomes are also missing. Players interested in a symbol chosen before the bonus and then enlarged can understand the broad structure, but a precise sequence and expected feature value require clarification. The overall maximum win and multiplier describe the game, not a special limit on the expanding-symbol mechanic.
