How to play today's puzzle by difficulty
Medium
Work in short passes across the grid. Use candidate notes when two or three options remain, then return to boxes with only one valid placement.
Hard
Hard grids reward structure. Track candidates carefully, compare linked rows and boxes, and remove contradictions early before committing to longer chains.
Expert
Expert play needs deliberate pattern checks. Build clean candidate maps, test eliminations across houses, and confirm each placement against the whole grid.
