A new kind of puzzle game!

Introduction

Doctor Esker has vanished, leaving behind only a mysterious book full of puzzles written in his own hand. Nobody has cracked his cryptic codes yet. Are you up to the challenge?

The game provides a deck of 73 cards which contain nine devious puzzles to solve. You can play through the puzzles solo or together with family and friends. Great for a party, a game night, or a lazy afternoon.

How it works

Each puzzle is composed of a set of cards. You can solve the puzzle by reading, comparing, arranging and pondering the messages, drawings, and artwork on the cards. Solving the puzzle reveals a sequence of numbers. When you think you’ve got it, gather the solution cards corresponding to the number sequence and flip them. If you see a message or image, you’ve solved the puzzle.

General Advice

The hints are meant to be used! Almost nobody, even experienced puzzlers, gets through without them.
