Crazy double-sided mind-manglers!

These great little mental-co-turning puzzles are double-sided, with balls dropping through holes from one side to the other.

The challenge is to get the ball to the puzzle-solving light bulb, finding a route through the tortuous maze along the way. Watch out, you’ll soon be disorientated, baffled and flummoxed – but stick with it, they CAN be solved!
