Choice of puzzles: Our alphadoku were designed and graded so that at the same level the higher the puzzle number, the more difficult the solution with this nuance that in our classification, at equal levels and numbers, symmetrical puzzles are a little easier to solve than asymmetrical ones. Indeed, the symetrical ones have an additional constraint - precisely to be symmetrical - so they have fewer empty squares to solve. Also note that the aspect of difficulty is subjective, because different solving techniques suit different people.
Why play alphadokus: The 25X 25 puzzles also provide extra training for hardened competitors and fans of classic 9X9 sudoku.

• Statements "Beginner" are fully resolvable by "Inclusion" while admitting other methods.
Symmetric and asymmetric puzzles:
An alphadoku puzzle, like a sudoku, is symmetrical when the squares that compose it are arranged equally around the central square known as the center of symmetry. This is only esthetic and does not change the resolution mode of the grid. Indeed it is the puzzle that is symmetrical and not the solution. However, the advantage of non-symmetrical puzzles is that, having one less constraint, they allow the elaboration of more difficult problems.
