Cool Circuits Puzzle

Cool Circuits is the challenging puzzle that dares you to complete an electrical circuit using eight seemingly simple pieces.

Start by choosing one of forty included paper puzzle cards and laying it on top of the puzzle box. The card illustrates a segment of the correct solution along with a smattering of hints as to how to place your pieces.

Cool Circuits are incredibly difficult to solve because each piece can be flipped as well as rotated in several orientations, and there is only one correct solution to each puzzle.

Portable puzzle box features pull-out tray for challenge card storage. Requires 3 x AAA batteries (which are included).
