Kakuro Classic: Number Puzzle

New: Daily Kakuro with a worldwide leaderboard. Solve a fresh puzzle every day and see how you rank against players around the globe. Now with an improved pencil mode

Kakuro is a crossword puzzle made of numbers: instead of words you enter digits, and instead of clues you get sums. A new puzzle every day — and it works completely offline.

HOW IT WORKS The grid looks like a crossword. Each row and column is divided into blocks, and every block has a target sum. Your job: fill the empty cells with digits from 1 to 9 so the sum adds up. The catch — within a single block, each digit can only be used once. Simple to learn, surprisingly tricky to master.

PENCIL MODE For tougher grids, the virtual pencil has your back. Jot down possible candidates directly in a cell without committing to an answer. One tap switches between notes and final entry, so you stay on top of even the largest puzzles.

DAILY KAKURO Every day brings a new, unique grid shared by players worldwide — with its own daily leaderboard. How fast can you crack it?

FOR BEGINNERS AND VETERANS Multiple difficulty levels let you start gently and work your way up to serious grids. Beat your own records offline, or take on the best players online.
