Description
This is a nice wooden puzzle, custom designed by Diamon Jim Tyler.
It measures around 9 x 9 cm. and fits into the palm of your hand. The seven pennies are included.
Begin with an empty board. The object is to start on a vacant circle and to move it once along a connecting line to another empty circle. This must be done with all seven pennies leaving the eighth hole vacant.
Most people can do four or five pennies, but doing all seven takes a knack. To understand how, watch the video.
