NYT Hard Sudoku 14th May 2024: One Step Solution
Stage 1: Critical breakthrough reached early, but after using advanced Sudoku concepts
Hidden single R7C1 8. Parallel scan for 3 on C4: R7C4 3. Hidden single R8C8 3.
Single digit lock on 8 in R9C8, R9C9: breakthrough R5C4 8 by parallel scan for 8 on C4, naked single R6C4 6.
Coincidence of single digit locks on 3 digits [1,6,9] in three cells of right middle major square R5C7, R5C8, R5C9 creates a Cycle of (1,6,9) in these three cells in R5.
Hidden single R4C8 2. This is the critical breakthrough in this seemingly very hard Sudoku.
Rest of the cells will be easy to resolve.
Identifying the Cycle (1,6,9) as a Coincidence of single lock digits provided the critical breakthrough. This is a powerful concept and Sudoku technique. It is equivalent to
triple digit scans of [1,6,9] in R4, and R6 and this is the easier way to identify the Cycle.
