How to Play Kakuro Puzzles

Kakuro puts you in that quiet, focused state where numbers click into place and the grid slowly reveals its logic. It suits anyone who loves Sudoku or crosswords and wants a puzzle that rewards patience and sharp thinking.

  1. Choose a puzzle from the available grid sizes
  2. Read the clue numbers written along the edges of each row and column
  3. Enter digits so that they add up exactly to each clue
  4. Make sure no digit repeats within a single sum group
  5. Fill every cell correctly to complete the puzzle and win

Controls

Tap or click a cell to select it, then type a digit from 1 to 9 to place your answer. Move between cells with the arrow keys or by tapping directly on the grid.

When does a round end?

A round ends when every cell in the grid holds the correct digit and all clue sums are satisfied.

Tips & Tricks

  • Start with the shortest sum groups — a two-cell group that adds to 3 can only be 1 and 2, which locks in both digits immediately
  • Cross-reference rows and columns at every intersection; a digit ruled out by one sum is often ruled out in the crossing sum too
  • High clue numbers in short groups are just as restrictive as low ones — a two-cell group summing to 17 can only be 8 and 9
  • When you are stuck, pencil in all possible candidates for a cell and eliminate them one by one as neighbouring groups get solved

Why people keep coming back

  • Two puzzles in one Kakuro blends the unique-digit rule of Sudoku with the crossing structure of a crossword

  • No repeated digits each number 1–9 can appear only once within any single sum group, keeping every puzzle fair and logical
