Can you collect all the nickels?
This puzzle makes for an excellent desk or coffee table puzzle, and it can be quite diabolical. The object is to collect all the nickels.
The board, which measures about 8" x 2", is deeply laser engraved with name and instructions. The nickels are made from 1/4" maple and are also laser engraved.
To play: arrange the 9 nickels in any sequence of heads & tails. Then remove any head and flip over neighboring coin(s). If there is a gap between coins after some moves, they are no longer neighbors. Repeat the process, selecting a head and flipping neighbors, as long as there is a head showing.
