About Medium Sudoku

This Medium Sudoku steps up to a 6x6 grid using numbers 1 through 6, arranged in six rectangular 2x3 boxes. It is the natural next challenge for kids who have mastered 4x4 puzzles and are ready for a bigger grid, more numbers to track, and a real logic workout that still fits on one printed page.

A 6x6 grid asks kids to hold more information in mind at once, six numbers checked across three overlapping groups for every cell. That strengthens working memory, sharpens process of elimination thinking, and builds the patience to scan a full grid methodically instead of guessing. It is strong practice for the multi step reasoning kids need in upper elementary math.

Scan each row, column, and 2x3 box for the numbers already filled in. Whatever number is missing from that trio of groups belongs in the empty square, so use process of elimination rather than guessing. Fill in the easiest squares first, the ones with the fewest open options, then work outward until the whole 6x6 grid is complete.
