What is 6×6 Medium Mini Sudoku?
6×6 Medium Mini Sudoku delivers a satisfying, compact solve that rewards candidate tracking without the time commitment of 9×9.
You fill a 6×6 grid with digits 1–6 so each row, column, and 2×3 box has no repeats.
Medium 6×6 puzzles typically contain 18–24 given numbers—enough to start, but sparse enough that you'll need candidate notes to track possibilities.
