Book of Monsters

Book of Monsters may sound like another traditional book slot, but Pragmatic Play takes the title in a completely different direction. Instead of reels, paylines and a randomly selected expanding symbol, the game uses a large 7 by 7 grid where connected creatures form winning clusters. Giant symbols can occupy almost the entire screen during ordinary spins, while the Free Spins feature develops one chosen monster from a single position into a colossal 7 by 7 FAT Symbol. Regular wins require at least five identical paying symbols connected horizontally or vertically. Diagonal contact alone does not join symbols into the same cluster. Larger groups provide stronger prizes, and several separate clusters can pay during the same spin. Book of Monsters does not use a conventional Wild, so every cluster must be created from naturally matching symbols. The paytable features a colourful group of unusual monsters, with stronger creatures producing the most valuable natural cluster wins. The base game does not use tumbles. Once the grid has been evaluated and all qualifying clusters have paid, the spin ends without removing the winning symbols. Its defining mechanic is instead the random appearance of supersized symbols. A regular monster can land as a block measuring 3 by 3, 4 by 4, 5 by 5, 6 by 6 or even 7 by 7. Every position covered by the block counts as one copy of that symbol, allowing a single oversized monster to create an enormous cluster immediately. A full 7 by 7 symbol covers all 49 positions and produces the largest possible natural group for the selected monster. Four, five, six or seven Bonus symbols trigger 5, 6, 7 or 8 Free Spins respectively. Before the feature begins, one regular paying symbol is selected randomly to become the FAT Symbol. Players can accept the awarded configuration immediately or use the optional gamble feature. The gamble can attempt to increase the starting number of Free Spins, up to a maximum of eight, or upgrade the FAT Symbol to the next more valuable monster. Each gamble carries the risk of losing the complete feature, so an unsuccessful attempt ends the bonus before any Free Spins are played. The FAT Symbol begins at a size of 1 by 1 and appears in a random grid position during every Free Spin. All natural copies of the selected monster that land are counted by a collection meter. Gathering 30 matching symbols grows the FAT Symbol to 2 by 2. Another 27 increase it to 3 by 3, followed by another 24 for 4 by 4, another 20 for 5 by 5, another 16 for 6 by 6 and another 12 for the maximum 7 by 7 size. The collection requirements become smaller at the later stages, giving a developed feature a realistic opportunity to continue progressing if enough matching monsters appear. Every FAT Symbol upgrade remains active for the rest of the feature. Once it reaches 4 by 4, for example, it continues appearing at that size until the meter completes the next stage. The symbol also changes position between spins, so its growing block can connect with different natural copies across the grid. Each size increase awards between 1 and 3 additional Free Spins, extending the feature while simultaneously creating a larger guaranteed block of the chosen monster. Once the FAT Symbol reaches 7 by 7, it fills the complete grid whenever it appears and no further size upgrades are available. The selected monster still uses its normal paytable value. Choosing to gamble for a higher paying FAT Symbol can therefore improve the value of every cluster created by the growing block, while gambling for more Free Spins provides additional opportunities to fill the collection meter. These two options create a genuine distinction between a longer feature and one centred on a more valuable monster. There are no bonus multipliers, sticky Wilds or separate respins. The complete potential comes from the size of the FAT Symbol, the value of the selected monster and the number of additional spins earned as it grows. An Ante Bet may be available in supported markets. It doubles the regular stake, adds more Bonus symbols to the grid and allows three Bonus symbols to trigger 4 Free Spins. This makes the feature considerably easier to activate, although the regular symbol prizes remain unchanged. A Bonus Buy may also be offered for 100 times the selected bet, providing direct access to the Free Spins feature with a random triggering combination. The gamble decision is still presented before the purchased feature begins, allowing the awarded spins or FAT Symbol to be risked for an improved starting setup. Book of Monsters has high volatility, a maximum RTP of 96.50 percent and a maximum win of 5000 times the total bet. Alternative RTP configurations of 95.50 percent and 94.50 percent may be supplied to individual operators. Its playful creatures and bright laboratory setting keep the presentation lighter than the title suggests, but the underlying feature is built around demanding collection targets and rare oversized results. The base game can surprise with a giant monster covering most of the screen, while Free Spins provide a clear progression path where every matching symbol moves the FAT Symbol closer to complete domination of the grid.
