Tome of Madness takes Rich Wilde from conventional reels to a 5x5 grid of connected symbols. Released by Play’n GO on 27 June 2019, the slot uses cascades to charge a four-stage Portal, with Abyss, Void and Other World changing the board as more winning symbols are collected. Its verified maximum win is 2,000x the total bet.
Tome of Madness pays groups of 4 or more identical symbols joined horizontally or vertically. Symbols in a successful cluster are removed and fresh icons drop into their positions, allowing another result to be evaluated under the same wager.
Tome of Madness links those cascades to a Portal meter that counts the symbols involved in wins. Reaching 7, 14, 27 and 42 symbols progressively adds Special Wilds, removal effects and a one-round Other World feature.
Tome of Madness has the following verified specifications:
Tome of Madness carries 91.59% RTP and a very-high 10/10 volatility rating in the Wildz listing. Available stakes and currency presentation can differ by operator, so the active game panel should be checked before real-money play.
Tome of Madness scans the full grid for matching symbols that share a side. Four connected icons form the smallest paying cluster, while larger groups use the corresponding multiplier in the paytable before all winning positions are cleared.
Tome of Madness then fills the cleared spaces from above and checks the board again. Cascades can extend a cycle and add further Portal charge without requiring a second bet, but replacement symbols are random and another cluster is never assured.
Tome of Madness places 2 Special Wilds at random after the meter records 7 winning symbols. At 14 symbols, a win involving an added Special Wild activates Abyss; at 27 symbols, the equivalent condition activates Void.
Tome of Madness makes Abyss remove the winning Wild’s row or column and sends those cleared symbols into the Portal count. Void instead picks one ordinary symbol and removes all copies from the grid, with neither effect giving the player control over the next layout.
Tome of Madness treats the Tome itself as a Special Wild able to stand in for regular symbols. Rich Wilde is a separate Multiplier Wild that substitutes for high-value icons and doubles the associated cluster payout with a 2x multiplier.
Tome of Madness can place Eye Marks at random board positions. Forming wins across marked cells opens them, and opening the required marks adds 2 Special Wilds once the current cascade sequence has no further wins; their addition does not guarantee another paying group.
Tome of Madness triggers Other World after the Portal counts 42 winning symbols. The award is 1 free round carrying 3 random Portal Effects, with one extra effect added for every three symbols above the trigger and a ceiling of 7 effects.
Tome of Madness begins this feature with 11 or 12 Eye Marks visible. If clusters open all of them, Cthulhu enters as a Mega Wild and drops one row after each cascade until it leaves the grid, although the complete eye-opening sequence cannot be forced.
Tome of Madness is served by Wildz with an RTP of 91.59% for the MGA configuration described here. The percentage expresses a theoretical average over extensive play rather than the return from a particular deposit or session.
Tome of Madness can perform above or below its RTP during a short run. Because the title exists in several mathematical versions, the information panel should be used to confirm the percentage attached to the game that has actually loaded.
Tome of Madness is rated 10/10, placing it in the very-high-volatility band on the Wildz scale. Returns can therefore arrive irregularly, and a session may include substantial variation between ordinary clusters and more developed Portal sequences.
Tome of Madness does not become less volatile because a previous cycle ended without a win. Each new paid round is independently generated, so stake choices should be based on an affordable budget rather than an expectation that a feature is due.
Tome of Madness has a documented maximum win of 2,000x the total bet. That ceiling is tied to the game’s cluster and feature system and is not a separate jackpot that grows as other customers play.
Tome of Madness lists none as its jackpot type in the platform record. Reaching 2,000x is an upper limit rather than a likely outcome, and Portal progress or Wild activity cannot be used to predict that result.
Tome of Madness starts with a review of the in-game rules, displayed RTP and available stake buttons. After a wager is chosen, the grid resolves all clusters, cascades and any resulting Portal Effects before the next paid cycle can begin.
Tome of Madness players should set deposit, loss and session limits that fit their own circumstances. Raising a stake increases the amount at risk and the cash value of a multiplier, but it does not improve the random probability of entering Other World.
Yes, Tome of Madness is available in mobile and desktop formats. Its 5x5 board, cluster rules, Portal stages and Cthulhu Mega Wild sequence remain part of the mobile version on compatible phones and tablets.
Tome of Madness may display controls differently according to screen size and browser. Device choice has no effect on the mathematical return, volatility setting or random production of winning symbols.
Yes, Tome of Madness has a demo mode enabled at Wildz. Virtual credits allow the grid, Wild types, Portal charging and Other World sequence to be viewed without making a real-money wager or receiving cash winnings.
Tome of Madness demo play should be used to understand the controls and feature order rather than to test a betting system. Free and real-money rounds remain random, and results in one mode provide no forecast for the other.
Tome of Madness is intended for adults who meet the legal gambling age applying in their province or territory. Casino regulation is provincial, so age limits, operator requirements and consumer protections are not uniform across the country.
Tome of Madness players should verify the operator’s licence details, payment rules and responsible-gambling tools before depositing. The game’s 91.59% RTP and very-high volatility should also be considered alongside a personal spending limit.
