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

A) Novice.
B) Apprentice (mainstream edition).
C) Master (75 Intersections, 4 Naked Pairs, 4 Naked Triplets, 3 XY-Wings: one in g1, one in g3 and one in g4, 1 X-Wing in g3). Select to view GRID numbers.
The advanced techniques are needed in 3 different grids.
