SudokuSolver Forum

There are four difficulties to choose from.
All four puzzles have the same solution.

A) Novice
B) Apprentice (mainstream edition).
C) Master (22 Intersections, 3 Naked Pairs, 1 Naked Triplet, 4 Naked Quads, 1 X-Wing in g1, 1 Two String Kite in g4, 1 Finned X-Wing in g3, 1 Uniqueness Test 1 in g2). Select to view GRID numbers.
If you spot the Uniqueness Test 1 first, the 3 other advanced techniques become superfluous!
Otherwise each of the 4 techniques X-Wing, Two String Kite, Finned X-Wing and Uniqueness Test 1 is required in a different 9x9 grid.
D) Guru (24 Intersections, 3 Naked Pairs, 1 Hidden Pair, 1 Two String Kite, 1 Turbot Fish, 1 Finned X-Wing, 2 Finned Swordfish, 2 Uniqueness Test 1, 1 XY-Wing, 2 XYZ-Wings).
