Explore creepy ways without losing your cool — literally!

The boundary between worlds is thinning, an ancient terror is awakening, and the very existence of the world hangs by a thread. You must investigate a series of horrific locations and uncover the unthinkable truth before the end of the world — or go mad trying to save it. Find the paranormal gates that have opened in our world, and be brave and strong because only then will you discover how to close the gates and save humanity.

In Tower of Madness, a three-dimensional clock tower, one foot tall and filled with marbles of four different colors, rises before you. Thirty supernatural tentacles protrude from the tower's walls in every direction in this high-intensity dice game, influenced by Lovecraftian horror. Fail your dice rolls and you will be forced to pull a tentacle from the tower. Any marbles that fall as a result directly affect your character, either adding to your discovery score or gaining magic and knowledge that man was not meant to have, or bringing madness. However, if you roll one of the three DOOM marbles, you will summon Cthulhu and end the game.

Explore each horrific location in the deck, each with its own unique dice challenge, in order to save the world before your luck runs out. The player with the most discovery points is declared the hero and wins the game. Otherwise, the insane players collectively enjoy a brief moment of victory as Cthulhu emerges, destroys the world, and eats them last... as a reward.
