Referred to as the Book of Books, this slot game of heightened volatility unfolds on a dynamic grid, ranging from 5x3 to 5x5, encompassing 40 pay lines during the Bonus Game. Within the base game, a collection mechanism empowers players to enhance their Free Spins experience with up to 10 expanding symbols, extra free spins, and multipliers.

To acquire these Powerups, players need to secure two scatters during the base game. These enhancements encompass one or two free spins, a single expanding symbol, or an expanding symbol multiplier of either x1 or x2. Accumulated in a meter, these Powerups are activated during the Free Spins round.

The panel size varies based on the initial scatters, reaching a maximum of 5x5 with five scatters. In the calculation of a regular win, panels with expanding symbols expand to cover the entire reel, earning an extra prize.

When four symbols of the same kind stack on a reel, they expand into a Monster Reel after line wins are settled. Each Monster Reel showcases a character from one of the four high-paying symbols, granting a unique extra prize after expansion. These prizes are tied to your current bet level and stand apart from regular line wins.

Should five Monster Reels of the same kind appear simultaneously, they transform into a Monster Takeover, engulfing all five reels. During this event, Monster Reels do not pay individual extra prizes, and no regular line wins are awarded.

Activate the bonus by landing three FS scatter symbols simultaneously in the base game, unlocking 10 free spins. This bonus game boasts superior odds compared to the base game for triggering the expansion of Monster Reels by landing four stacked symbols of the same kind on a reel.

Trigger the bonus with four FS scatter symbols simultaneously in the base game, securing 10 free spins. At the bonus's commencement, one of the four high-paying symbols is chosen as the main symbol for the feature. Only the selected main symbol can expand into Monster Reels during the bonus.

As a Monster Reel of the chosen symbol expands on a reel, the indicator above the reel activates for the remaining bonus duration. At the conclusion of all remaining spins, Monster Reels expand on all reels with activated indicators. The Upgrade scatter symbol, if landed, upgrades the selected main symbol to the next higher-paying symbol, if applicable. The newly chosen symbol becomes the sole symbol capable of expanding into Monster Reels, and the indicators above each reel also upgrade to match.

Expanding Reels is a casino game mechanic that is often found in online slot machines and video slot games. It is a feature that allows the reels to expand and increase the number of symbols on the screen, potentially leading to more winning combinations.

When a player hits a certain combination of symbols or triggers a bonus round, the reels will expand to add more symbols, increasing the number of ways to win. The expanded reels can also add new symbols to the game, such as wilds or multipliers, increasing the chances of hitting winning combinations. Some games also feature special symbols that can trigger the expanding reels, such as scatter symbols or special bonus symbols.

This game mechanic can add an extra layer of excitement to the game by introducing a new way to form winning combinations. It also allows for more flexibility in terms of where the symbols can appear on the reels, which can make it easier for players to hit winning combinations.
