Master Sudoku
Master Sudoku
Master Sudoku is the highest difficulty tier on Sudoku a Day. These grids are designed for solvers who already navigate expert patterns comfortably and want puzzles that resist quick resolution. You’ll often need to combine techniques rather than apply one pattern in isolation: forcing chains, finned X-Wing, and almost locked sets are common unlock points. Solve times vary widely, from 40 minutes to more than an hour, depending on how quickly key structures appear to you. Keep notes meticulous, avoid speculative guessing, and verify each elimination chain. If you want a complete strategy map, start at Sudoku strategies. Prefer print? Weekly files are available at printable master Sudoku. For a slightly lighter challenge, step back to expert Sudoku.
