Mini Sudoku #19 was the medium 6×6 of Thursday, October 15, 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 25 naked 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 25 on our scale (easy below 25, medium below 34, hard below 45, expert above).
