Kakurasu by Solviq

Kakurasu is a calm, clever number-logic puzzle from Japan. Ink cells so that every row and every column adds up to its clue. The twist: each cell is worth its position. In a row, a cell counts its column number; in a column, it counts its row number. Every cell has its weight. Every puzzle has exactly one solution and can be solved by logic alone. No guessing.
