This edition of Professor Storm’s advent calendar covers a number of Christmas inspired puzzles and solutions – one for each day in December. In order to solve the tasks, you need to use your brain. Sometimes you will have to do math, at other times you need to use you sense of logic, and sometimes you need to revert back to your school learning. The solution to the puzzle of the day is given to you with your next puzzle. In between each puzzle there is a dated page – this is the puzzle separator, so that you don’t see the next day’s puzzle – and the answer to your current puzzle.
The theme covers norms and special occasions, such as recycling, a festival of colors, the naming of nisse children, and Gutenberg's birthday
The eBook includes a "Nissepedia," where you can read about the nisse, the Christmas nisse, the misprint nisse, the church nisse, rice porridge, nisse beer and porridge spoon puzzles.
Also available in a Danish edition.
