Kakuro

Here's how to solve kakuro:

- Place a number from 1 - 9 in each white square in the grid such that the sum of the white squares in each run of cells matches the total in the light grey square at the start of that sum.

- Sums run either horizontally or vertically. A number cannot repeat within each sum. Thus if there is a sum total of 4 from two squares, it must be 1 and 3 in some order, not 2 and 2.

That's it Each puzzle in this collection has a single solution that can be reached through considering the number options for each square: you'll never need to guess to solve these puzzles.
