Game introduction

What is Kakuro?

Kakuro is often described as a number crossword. Every horizontal and vertical run has a target sum, and the digits inside a run cannot repeat.

Crossing cells belong to both a row and a column, so one confirmed digit narrows two clues at once. New puzzles vary the grid size, digit set and hidden solution.
