I have not played the other 9, started w/ 10. Fun. Hidden objects sly. Puzzles quite good. I am a bit amused by "eagles." Sometimes, instead of a Bald Eagle (USA), it is a Polish Eagle. Makes me wonder if the creators are, in fact, in/from Poland. It's OK with me since all of my forbears are Polish, hence my recognition of the national symbol. A few touches of religion which, again, makes no never-mind to me, but, I think, might attract or repel some folks.
