Pure mental arithmetic meets daily competition. Today's grid has zero givens - just operation cages to crack. Everyone gets the same numerical maze. Fast mental math wins the leaderboard.
How to Play
Fill the grid so no number repeats in any row or column. Each cage shows an operation (+, -, x, /) and target. Find which digits produce that result. Complete today's puzzle to score and rank against others.
Mathdoku Tips
Mathdoku combines arithmetic with Sudoku rules. Rows and columns must stay unique, but cages can include repeated digits depending on the arithmetic constraints.
Start with single-cell cages and small sums to anchor the grid, then work outward with cage combinations.
