How to Play Consecutive Sudoku

  1. Standard Sudoku rules apply.
  2. A white dot between two cells means they differ by exactly 1.
  3. NO dot between cells means they do NOT differ by 1.
  4. The absence of a dot is just as informative as its presence.
💡 Pro Tip
Start by looking at cells surrounded by no dots — their values are heavily constrained since they can't be consecutive with any neighbor.

Frequently Asked Questions

Is the absence of a dot a real constraint?

Yes — an empty edge means the two cells must NOT be consecutive. For instance, 4 and 5 cannot sit next to each other across an unmarked edge.

How does Consecutive Sudoku differ from Kropki?

Kropki uses both consecutive (white) and ratio (black) dots. Consecutive Sudoku uses only the consecutive rule with one dot type.
