It's a dark and stormy night as you arrive at Grisly Manor. The house is curiously empty and grandpa is nowhere to be found! But familiar objects have been re-engineered to create puzzles for you. Clues abound, and as each puzzle is solved, the solution to others present themselves. As well as new puzzles, of course. Grandpa obviously spent a lot of time making sure that nobody could solve the myriad of puzzles strewn about the house. Nobody but you, his favorite grandchild…Can you solve the mystery of Grisly Manor?
