6x6 Kropki Puzzles

The 6x6 Kropki adds the digits 5 and 6, and with them a new double: 3 and 6 can now share a black dot, next to 1 and 2 and 2 and 4. White dots still join digits one apart. The boxes are two rows tall and three columns wide.

Easy grids start with fourteen digits, Medium with seven, and Hard often with none, leaving the dots to decide every cell. Each grid has one solution.

The Three Doubles of a 6x6 Grid

Only three pairs can share a black dot here: one and two, two and four, three and six. So a cell touching a black dot holds 1, 2, 3, 4 or 6, never 5. Note that early: 5 can only meet a white dot, toward 4 or 6.

Reading the Empty Borders

Because every qualifying pair is marked, a border without a dot is a clue as well. Two neighbors that show no dot cannot be 2 and 3, or 3 and 6. On Hard grids, these silent borders often unlock the first digit.

From Easy to Hard

Easy sheets give fourteen of the thirty-six digits and feel close to a regular sudoku. Medium halves that. Hard keeps only what the deduction needs, so most Hard grids are solved from the dots alone.

Frequently Asked Questions

Why is there no black dot next to a 5?

A black dot joins a digit and its double. On a 6x6 grid, 5 has no double and is not the double of any digit, so it can only take white dots, toward 4 or 6.

Is a 6x6 Kropki harder than a 4x4?

Usually, yes. There are more digits to place and more pairs to rule out, but the grid stays small enough to see whole, which makes it the natural step before the 9x9.
