Dodeku

What is Dodeku?

Dodeku is a daily number puzzle that challenges you to fill a grid so that the sums of each row and column match the target numbers printed along the edges. Each day brings a new puzzle, and an archive lets you revisit past challenges.

How to play Dodeku

You're presented with a grid and a set of perimeter numbers indicating the required sums for each row and column. Your task is to determine the correct values for the cells, using logic and arithmetic to make every row and column add up to its target. The game tracks your moves and offers tools like unlocking tiles or recalling all values if you get stuck.

Tips & strategy

• Start with rows or columns that have very small or very large target sums, as they often limit the possible values.
• Use process of elimination: if a row's sum is already close to its target, the remaining cells must be small numbers.
• Pay attention to intersections—each cell belongs to both a row and a column, so its value must satisfy both constraints.
• Work systematically rather than guessing; logical deduction will narrow down the options.
• If you're stuck, use the unlock or recall features to get a nudge without losing progress.
