Since the success of "Spirit of the Ancient Forest," the authors have tried too hard to vary the puzzle in convoluted ways. I wish they would go back to basics and write close variations of "Spirit" and "Witch's Tales."
This game doesn't quite hit the mark I have been seeking, the ones set by the Solitaires 1, 2 & 3, plus the Solitaire Christmas and Halloween Solitaire games. Each puzzle page of Mystery Solitaire is too much like the others.
I love this kind of solitaire. It requires the ability to plan in a way that's almost impossible in the various standard solitaires. Give it an honest try. Warning: requires focus.
