Our Puzzles
At, we offer the best puzzles you can come by. Many books and websites rate the difficulty of their puzzles based on the number of given clues or the opinions of their players or creators. These methods are rudimentary, subjective and lack in their mathematical integrity. Often times, those other sites actually only provide one level of logical difficulty--easy! It's a no brainer. At, we do not accept anything but the best. We offer logically sound rated puzzles as well as the tutorials to help you get through them. Take a look at our tutorials or difficulty articles to see what truly defines the logical difficulty of a puzzle.

All our pentillions of puzzles are symmetric (with the exception of the order 4 Latin Squares), and each of our puzzles is categorized by its logical difficulty. Furthermore, all our puzzles present the minimum number of given clues, which means if any given clue along with its symmetric counterpart were removed, the puzzle would either be unsolvable or would belong to a different difficulty level. The only exception to these rules are the beginner level puzzles. The beginner level puzzles require the exact same logical tactics as the easy level puzzles and provide more than the minimum number of clues.
