Mutual Expectations

I think the difficulty level depends on who is working the puzzle. My aunt is 90 years old and has dementia. I'd say this was somewhat hard for her. But one thing I have noticed about Ken Zylla puzzles is that there is a lot of writing (signs, license plates, etc.) on a lot of them. This seems to help my aunt be able to put together more of the puzzle on her own. She had been struggling with puzzles lately until we bought these. She is able to work some of them entirely on her own, which is very much appreciated. So, long story short, Ken Zylla puzzles area good option if you are buying for a dementia patient. (And I like them, too!) :-)
