Easy Kakurasu

An easy Kakurasu is a small 4 by 4 grid, so the row and column targets settle it quickly. It is the best place to learn how the weights add up, and every one has exactly one solution.

Difficulty

Larger grids have more cells to weigh. Every puzzle has one solution.

4×4 grid. Shade cells so each row and column of shaded squares sums to its edge target.

Two pages: the puzzle and its shaded answer. Every puzzle has one solution, checked by the same engine as our KDP studio.

How to solve a kakurasu

Shade squares so the weighted totals along each row and column match the numbers on the edges.

The method

1Know the weights. In each row a shaded square is worth its position from the left, 1, 2, 3 and so on; in each column, its position from the top.
2Hit each target. The shaded squares in a line must add up to that line edge number. Find the combinations that reach it.
3Use the extreme totals. A small target keeps the big-weight squares blank; a target near the maximum shades most of them. Start where the choice is forced.
4Cross rows with columns. A square must satisfy both its row target and its column target. Where only one choice does both, lock it in.

The one rule: Shade squares so each row and column of shaded weights adds up to its edge target.
What the answer page shows: The solved shading is printed at the back.
How the grades differ: Larger grids bring bigger targets and more combinations to weigh.
Good for: Solvers who like a little arithmetic with their logic.
