The chocolate Tetris style puzzle from Meiji presents and interesting dilemma: eat the chocolate or solve the puzzle. The pieces fit into the case perfectly if you fit them correctly. The chocolate doesn’t melt at room temperature, so you have plenty of time to decide what to do. Of course, there’s an easy solution for those last few pieces that won’t fit in- bit off the ends to make them fit. That’s sort of like peeling the stickers off your Rubik’s Cube but a lot tastier. The types of chocolate determine the puzzle difficulty level: White Chocolate is easy. Milk Chocolate is for a Beginner. Black Chocolate is for an Expert!
