The higher the identification number of the puzzle, the more difficult the solution will be.
• Beginner puzzles are fully solvable using the "inclusive method" while allowing other processes.
• Confirmed puzzles are fully solvable using the "inclusive method" and the "exclusive method" while allowing other means.
• Expert puzzles are solvable using the "inclusive method", the "exclusive method" and the "exclusive pair method". Sometimes you will have to go through the "multiple choice method", once per problem.
• Extreme puzzles are very difficult. They are resolvable by "inclusion", "exclusion", "exclusive pair" and "multiple choice". Depending on the level of the puzzle, you may be confronted from one to ten successive hypotheses by multiple choice.
By hypothesis, we mean here a supposition on the solution of an empty square, thus here a not certain solution.
* "Fully solvable" does not mean "only solvable".
Example: Beginner puzzles, while being completely solvable by "inclusion", may well have squares that admit more complex solutions.
