Kakuru
A daily cross-sum number puzzle: fill the grid so every run adds up.
About Kakuru
Kakuru gives you a grid of blocked and open cells, each open run carrying a clue — the sum its digits must add up to. Fill every run with digits 1 to 9, never repeating one within a run, until the whole grid checks out. There is exactly one solution, the same puzzle for everyone each day, and you can share your time and mistake count without spoiling the answer.
How to play
Read each run's clue — the sum its digits must add up to.
Fill every open cell with a digit 1–9, never repeating one within a run.
Submit the finished grid and share your time — it reveals how you did, not the solution.
