Rules of the game

TOME OF MADNESS BINGO is a bingo video game.

Activate up to 4 BINGO cards, which can be toggled on and off by clicking on them individually. Press NEW CARDS to reset the numbers on all active cards. Each card has 15 numbers, allowing players to play up to 60 numbers in total. Press PLAY to start the round. 30 balls will be drawn from a pool of 90.

Winning combinations are formed when matching numbers create a valid pattern on an active Bingo card. There are 13 different patterns displayed in the game, with their corresponding prizes indicated below them. These patterns must be completed entirely to award their prizes. Winning combinations will be shown on the cards. Pattern prizes will be awarded if more than one pattern is completed on the same card. However, the highest prize will only be awarded if a pattern is completely covered by a higher-paying pattern.

Activate the BONUS feature after all 30 balls have been drawn, when only one ball is needed to win a prize equal to or greater than 12x the card stake. The cost of each BONUS ball is displayed on screen and is based on the potential winnings. Up to 13 BONUS balls can be purchased. The 13th BONUS ball is unlocked when only one ball is needed to win a prize equal to or greater than 200x the card stake.

The MYSTERY TAKE BONUS is activated by getting a Rail Pattern on the card. During the BONUS, a random prize is awarded which can be 300, 350, 400, 450, 500, 550, 600, 650 or 700 multiplied by the bet per card.

The SECRETS OF TOME BONUS is activated by obtaining a Perimeter Pattern on the card. The BONUS begins with 5 selections out of 16 possible. Choose from 16 mythical tomes. Each reveals either a BONUS prize or a +1 Selection with a BONUS prize. Available BONUS prizes include 50, 60, 70, 80, 90, 100, 105, 110, 120, 140, 150, 160, 175, 180, 190, and 200, and are multiplied by the card stake. When a BONUS prize is won, the prize amount is added to the BONUS counter. Three of the 16 selections offer a +1 Selection with a BONUS prize. When a +1 Selection with a BONUS prize is won, the prize amount is added to the BONUS counter, and an additional selection is awarded. The maximum number of selections during the BONUS is 8.

The TREASURE OF CTHULHU is activated by achieving BINGO within the first 30 balls on the 4 active cards, each with a minimum bet of 1. The TREASURE OF CTHULHU awards a fixed prize equal to 5000 multiplied by the bet per card.

The RTP is 93.54% - 97.38%. The game's RTP is 97.38% when playing with 4 cards and without buying extra balls.
