NYT Hard Sudoku 9th May 2024: Quick One Step Solution
Stage 1: Takes least time to get to the critical breakthrough point
Hidden single R8C6 3. Naked single R8C5 1, R8C4 5, R8C2 8.
Parallel scan for 6 on R8: R8C1 6.
Triple digit scan for [2,4,8] on left middle major square creates Cycle (7,9) in C2 and Cycle (2,4,8) in the major square.
This is the chief powerful breakthrough pattern to break open the game.
To ease up the solution identify Cycles (1,5) in left bottom major square, and in C2.
Start breaking open the game with naked single R8C8 2, followed by R8C7 4.
Form the single digit locks thoroughly.
It is unreal that the hard Sudoku opens up so early. Nevertheless, rest of the valid digits will be straightforward.
