Players enter a room that is decorated like a life-sized box of chocolates.
The floor is padded with what feels like velvet. On the walls are scraps of paper you'd find in a chocolate box: Nutrition facts, etc.
In the center are giant chocolate truffles, nestled in dents on the floor.
Players notice that there is an empty spot in the 3 x 3 grid.
One player absently pushes against a truffle and realizes that it can roll. The player rolls it into the empty spot.
One player notices that on the wall there's a tag showing how the truffles should be arranged.
Players realize they can only move one piece at a time, like a puzzle.
They keep rolling pieces around, trying different arrangements, until they get it right.
Success! They solved the puzzle!
