📖 About

Calcudoku (also known as KenKen) is the arithmetic puzzle that combines math with logic! Fill a grid with numbers so each row and column contains unique digits. But there's a twist—grouped cells (cages) must produce a target number using a specified operation. Addition, subtraction, multiplication, and division puzzles exercise both your math skills and logical thinking!

🎯 Objectives

Fill the grid with numbers 1-N (where N is the grid size) such that no number repeats in any row or column. Each cage must produce its target number when the operation is applied to its cells. Pure logic with a mathematical twist!

🎮 How to Play

Click empty cells and use the number pad or keyboard (1-4) to enter numbers. Each cage shows a target result and operation. Numbers in each cage must produce that result when combined with the operation.

💡 Tips

• ✓ Look for cages with only one cell - that's the answer!
• ✓ Use row/column constraints to eliminate possibilities
• ✓ Start with cages that have forced solutions
• ✓ Division and subtraction cages have limited options
