The device is simple. The board lights up and the translucent pieces can be placed in various positions. As you would expect, as colors overlap, new colors are made. This means that one has to know the basic color combinations that produce other colors.As interesting as it is, I found the solutions to be a little too simplistic. There were only a few puzzles in the entrie book that made me scratch my head a little. Yet, I still enjoyed playing with it and will most likely take it out every once in a while to tinker with again.Just don't expect to be completely baffled by this. It's worth the low price point for a few hours of light puzzle solving fun.
