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.
