• Puzzles "Beginner" are fully soluble by "Inclusion" while admitting other methods.
• Puzzles "Confirmed" are fully soluble by "Inclusion" and "Exclusion" while admitting other methods.
• Puzzles "Expert" are soluble with "Inclusion", "Exclusion, and "Multiple Choice". These puzzles do not require more than one hypothesis by multiple choice.
• Puzzles "Extreme" are very hard. They are soluble by "Inclusion", "Exclusion, "Exclusive pair" and "Multiple Choice". Depending on the level of the puzzle, you may be facing between one and ten successive hypotheses by Multiple choice.
By hypothesis we mean a supposition about the solution of a square in the absence of any logical reasoning.

* "Fully soluble" does not mean "only soluble".
Beginner puzzles, while being completely soluble by "inclusion", may well have squares that admit more complex solutions.
