📖 About

Kakurasu is the clever Japanese logic puzzle that combines simple addition with logical deduction! A grid of cells awaits your selection, with row and column numbers as clues. When you mark a cell, it contributes its column number to the row sum and its row number to the column sum. Use the target sums to determine which cells must be marked. Simple arithmetic, satisfying logic!

🎯 Objectives

Mark cells in the grid so that each row's sum of column values and each column's sum of row values match the given clues. Every marked cell adds to two different sums—use this constraint to deduce the correct pattern!

🎮 How to Play

Click cells to toggle them. The row clue shows the sum of column values for cells marked in that row. The column clue shows the sum of row values for cells marked in that column.

💡 Tips

• ✓ Look for rows or columns with clue 0
• ✓ Start with rows/columns with high clues
• ✓ Each cell is worth its row number
• ✓ Think about which combination adds up
