Weighted Grid
Every column has a value — shade cells to hit each row and column target.
About Weighted Grid
Weighted Grid (Kakurasu) gives each column and row a value. The clue to the right of a row is the sum of the column values of its shaded cells; the clue below a column sums the row values. Find the one shading that fits every clue.

How to play
- The small numbers on top and left are the values of each column and row (1, 2, 3…).
- A right-hand clue = the sum of the column values of shaded cells in that row; a bottom clue = the sum of the row values of shaded cells in that column.
- Find the unique shading that meets every clue.
Sizes 5×5 / 6×6 / 7×7. Targets turn green when met, red when exceeded.
Tap a cell: empty → shaded → dot (not shaded) → empty. Right-click cycles backwards.
Tips & strategies
- A clue of 1 can only come from the first cell.
- The largest clue usually needs almost the whole line.
- Write clues as sums of distinct values and cross-check with the other direction.
