Mathematical Reasoning Score
Your Mathematical Reasoning Score measures solving efficiency. Each puzzle cell tracks how many attempts it took to place the correct digit. Fewer attempts per cell means a higher score. Solving every cell on the first try gives 100%.
Your score will be saved after you sign in.
Place the digits 1-9 so every row, column, and diagonal adds up. Use each digit once.
