this is a very nicely made puzzle by Hideaki Kawashima.not terribly difficult, but the movement is very tight.

Operation is very precise at normal humidity. Furthermor...

Tom quickly determined that the original had at least 15 solutions. Both Tom and Markus subsequently went to work, both coming up with interesting vari...
