Slow Squares

Printable Kakuro

Kakuro is a crossword with sums where the clues would be. Fill the white cells with digits from 1 to 9 so that every run — across and down — adds up to the number in the grey cell at its head, and no digit stands twice in any run. The sums are given at the start; the rest is the puzzle.

Every day there is a new board in each of three sizes, dealt to everybody alike and solvable without a single guess. Pick a size, print the sheet, and take it wherever a screen would not go — a pen is all it takes.

How to play

Fill the white cells with digits from 1 to 9 so that each run of cells — across or down — adds up to the number at its head.

A clue cell is cut by a diagonal: the number above it is the sum of the cells to its right, the number below it the sum of the cells beneath.

Within one run no digit appears twice.

Tap a white cell and pick a digit on the pad under the board; the same digit again clears it. With notes on, digits are pencilled small in the cell instead.

A reddish cell holds a digit its run already has, or sits in a run whose sum has gone wrong; a sum greys out once its run is done.

Solved: every run adds up to its number, and no run holds a digit twice. The sums come with the board; the digits in the white cells were filled in, which is why they are in plum.
