About This Expert Sudoku Puzzle
This expert Sudoku for Monday, May 25, 2026 (5/25/2026) starts with 25 given numbers and has exactly one solution. A logic solver places 10 of the 56 empty cells with 10 hidden singles, 4 locked-candidates steps, 2 naked pairs and 1 x-wing before it stalls.
Hardest technique needed: beyond the guides on this site. A solver using singles, locked candidates, pairs, triples, X-Wing, Swordfish and Y-Wing stalls with 46 cells still empty, so expect to need longer chains. The puzzle still has exactly one solution.
