Cool Circuits Junior is the follow-up to the award winning Cool Circuits, named Puzzle of the Year by Game Magazine. This brand new set of 40 unique puzzles for ages 6 years and up includes the addition of 6 orange barriers which simplify the puzzle by limiting the building of each circuit on the game board. Once a new circuit is completed on the game board, blue lights light up and music plays. The tune played is the William Tell Overture, known to millions as the theme to the Lone Ranger. Children will experience hours of fun as they go to the next challenge and see if they can complete it. The challenges increase in levels of difficulty as the next puzzle is attempted.
