How to Play Kakuro
Kakuro is the ultimate cross between a crossword puzzle and Sudoku. Black cells with diagonal slashes contain clue numbers: the top-right number is the across sum for that horizontal line of white squares, and the bottom-left number is the down sum for the vertical column below.
↗️ Across Clues
Sum of all consecutive white squares extending to the right until a black divider.
↙️ Down Clues
Sum of all consecutive white squares extending downward until a black divider.
🚫 No Duplicates
Each digit (1–9) can appear only once in each continuous run.
