How to Solve Kakuro – Beginner’s Guide

🧩 What Is a Kakuro?

Kakuro is a logic-based number puzzle often described as a “crossword with digits.” Every white cell must contain a digit from 1 to 9 so that each horizontal or vertical block of consecutive white cells adds up to the target sum shown in its adjoining black clue cell. Digits cannot repeat within the same block.

📝 How to Read the Clues

Each black clue cell displays a target sum and the direction it applies to:

  • Across 16 — the digits in the contiguous white cells to its right must total 16.
  • Down 7 — the digits in the contiguous white cells below must total 7.

🧠 Solving Strategies

Start with blocks that have very limited combinations. A sum of 3 in two cells, for instance, must be 1 + 2. Use cross-referencing: when an across block shares cells with a down block, each narrows the other’s options. Write small pencil marks to keep track of candidates and eliminate digits that violate uniqueness or exceed the required sum.

🎯 Tips for Beginners

  • Tackle blocks with the fewest possible digit sets first (e.g., 4 in two cells → 1 + 3).
  • Remember digits cannot repeat within a block.
  • Use light marks to note candidate digits and erase as you narrow options.
  • Continuously toggle between across and down clues to refine choices.
  • Stay methodical — avoid guessing; every puzzle has a logical path to the single solution.

🛠️ Practice Makes Perfect

Begin with smaller Kakuro grids to master common digit combinations. As your confidence grows, move on to larger and higher-sum puzzles. Each Kakuro has exactly one solution you can reach through careful reasoning.

Happy solving!
