Daily Medium Mini Sudoku — 6×6

The daily medium mini sudoku is the 6×6 sweet spot — fewer givens than easy, requiring real elimination across rows and columns to crack, but still solvable in under 10 minutes once you spot the first chain. A 6×6 grid divides into six 2×3 boxes, and the medium tier puts the constraint right where it makes you work: enough digits filled to make scanning feel productive, sparse enough that you can't coast on lock-out alone. A fresh puzzle every visit means the daily medium mini never repeats. The 6×6 format scales the classic sudoku rules down without losing any of the deductive flavor — you'll use hidden singles, naked pairs, and box-line interaction here at a smaller scale, which makes it the ideal trainer for techniques you'll later apply to 9×9.
