How to Play

Fill the grid so every row and column contains each digit exactly once (Latin square). Cages must satisfy their arithmetic target.

👆

Click a cell to select it, then use the number pad or keyboard to place a digit.

🔲

Each bold-bordered cage shows a target number and operation (+, −, ×, ÷). The digits in that cage must produce the target using that operation.

🚫

No digit can repeat in the same row or column. Conflicts are highlighted in red.

💡

Single-cell cages are freebies — the target is the answer. Start with those and work outward.

🏆

Fill every cell correctly to complete the puzzle. Use clues if you're stuck.

About medium KenKen

The grid grows to 4×4 and subtraction enters the mix alongside addition. With 16 cells and more cage combinations, you can no longer brute-force every possibility in your head.

Start listing what each cage can hold. A "3−" cage with two cells in a 4×4 grid can only be (4,1) or (1,4). Cross-reference with what the row and column already contain, and you'll frequently pin a cell without touching any other cage. This list-and-eliminate approach scales to every difficulty level.
