Each puzzle has one and only one unique solution, and each can be solved using only pure logical deduction-guessing and trial-and-error methods are never required for these puzzles. If you're new to numbergrids, try the smaller puzzles first, then move on to the larger ones.
Additional constraints (here, on 3Ã3 Sudokus) lead to a smaller minimum number of clues. 1  3doku: no results for this variant. 2  Disjoint Groups: some 12-clue puzzles have been demonstrated by Glenn Fowler. 3  Hypercube: various 8-clue puzzles (the best possible) have been demonstrated by Guenter Stertenbrink.
