You can take many steps to prevent short circuits: unplug electronics when not in use, or only use grounded outlets. But a much more entertaining way is to play IQ Circuit. The object of IQ Circuit is to connect all of the dots with a path. Each path must start and end at a dot, and all of the double-sided puzzle pieces must be placed on the game board. Unconnected path pieces result in a fictitious short circuit (there is no actual current) and are not allowed. IQ Circuit is an elegant, compact travel game with 120 challenges in 5 levels. There is only one solution, and yes, the answers are included.
The ten pieces in IQ Circuit are double-sided. However, the rectangular pieces can also be placed blank-side-up, making them triple-sided.
