# Free printable Kakurasu with answers

Kakurasu is a shading puzzle driven by sums. Each column is worth its position number toward its row total, and each row is worth its position toward its column total. Shade cells so each row and column of shaded squares hits the target printed on its edge. Every puzzle here has exactly one solution.

## By size

Size is what makes a Kakurasu harder: a bigger grid has more cells to weigh and larger sums to balance. Start on a 4 by 4 and work up to a 7 by 7.

## One answer, every time

Every puzzle is generated by drawing a shading, reading its true sums, and running a solver that proves one shading matches. The shaded grid prints as the answer key.
