Mini Sudoku #22 was the hard 6×6 of Sunday, October 18, 2026, with 11 clues given and 25 cells to fill. Our technique solver, the one behind the hint button, fills it in 25 steps using 20 naked singles and 5 hidden singles; no pencil-mark technique is needed, so every cell can be placed by scanning rows, columns and boxes. That profile gives it a difficulty score of 38 on our scale (easy below 25, medium below 34, hard below 45, expert above).
