I have been enjoying this site since I upgraded but now it won't open and I miss doing the jigsaws which are very relaxing! It says it is loading but doesn't.
I had the same problem. Any Microsoft online game fails in Windows 10 when Apple's Bonjour service is turned on. Turning off Bonjour restores Solitaire, Minesweeper and others. Don't know if this is a Microsoft issue or an Apple issue. The version of iTunes I'm using is 12.3.2.36. Bonjour is Apple's device discovery service.
