Tome of Madness Gameplay

Exploring the Tome of Madness online slot by Play’n GO unveils a thrilling adventure on a 5×5 grid with cascading symbols designed to increase winning potential. Launched in 2019, this high volatility game features an RTP of 96.59% and a maximum win of 2000 times your stake, making it a compelling choice for players seeking substantial payouts. Starting gameplay requires selecting a bet from $0.10 to $100, easily adjusted using the plus and minus buttons.

Once the game begins, achieving wins involves forming clusters of four or more symbols that touch either horizontally or vertically. Each win charges a Portal that unlocks powerful effects and additional special wilds to enhance winning opportunities. For example, collecting 14 symbols adds special wilds to the grid, while 27 symbols trigger either the ABYSS or VOID effects, which remove rows, columns, or all instances of a specific symbol to extend the cascades.

The game’s pinnacle, the OTHER WORLD FREE ROUND, is triggered after collecting wins on 42 symbols. This bonus round intensifies gameplay with up to 7 random Portal Effects and the potential unleashing of the MEGA WILD Cthulhu symbol, which cascades down the grid to boost win possibilities significantly.

For newcomers or those looking to experience the thrill without wagering, the slot demo is available for free on this page, allowing you to enjoy the dynamic features and unique gameplay of Tome of Madness at no cost.

Our Review


Tome of Madness, crafted by Play’n GO, deserves a rating of 4 out of 5. The game stands out with its cascading reels and cluster pays, which dynamically enrich the playing experience. The high RTP of 96.59% aligns well with industry standards, offering players a fair chance at wins. Key features like the ABYSS and VOID effects, along with the MEGA WILD Cthulhu symbol, amplify gameplay excitement. However, the high volatility may turn off players seeking more frequent wins. Broadening the appeal could involve introducing options for adjustable volatility. This adjustment would cater to a more diverse audience, enhancing user experience across different play styles.
