Bought a copy of “Hart-to-solve brainteasers over the weekend. So far that title has been a disappointment – most of the problems assume that the reader has not had any formal training in problem solving – so the hard parts of finding a solution seem to be reinventing the tools needed to tackle the problems. Especially, annoying since the answers section just list answers without telling the reader how to solve the problems. Defiantly something I am going to have to keep in mind if I go through with writing a puzzle book.
This was problem #19 on page 12 of that book:
Using numbers 1,2,3,4,5, and 6 put each of the numbers in a circle with the constraint that no circles connected by a line can contain adjacent numbers. For example the circle with a three in it cannot be connected to either a circle with a two or a four.
