LinkedIn Mini Sudoku Answer

Start with rows, columns, or 2×3 boxes that already have the most filled cells — they're most constrained.

For each empty cell, list which numbers 1–6 are missing from its row, column, and 2×3 box. If only one number fits, fill it in.

If a number can only go in one cell within a row, column, or box — place it there even if other numbers are also candidates for that cell.

Each 2×3 box boundary (after rows 2 and 4, and after columns 3) acts like a hard constraint — use it to narrow options quickly.

Fill every empty cell of the 6×6 grid with a number from 1 to 6.

No number can repeat in any row or column.

Each of the six 2×3 rectangular boxes must also contain 1–6 exactly once.

Blue pre-filled cells are your starting clues — work from those to solve the rest by process of elimination.
