About difficulty
I recommend to beginning players leave for last the difficult puzzles (rating higher than 7), and try to solve first the easy and medium difficulty.

My scale of difficulty is this:

1 - 4.5    Easy
5 - 6.5    Medium
7 - 8    Difficult
8.5 - 10   Hard

If in these selections you think I should add other puzzles, let me know. All contributions are welcome. For example, what other topics you think interesting?

I appreciate your suggestions and recommended levels!
