Magic Square Generator – Same Row/Column/Diagonal Sum

Generate unlimited puzzles. Choose 3×3 or 4×4. Set a Target Sum (must be divisible by size), and fill the blanks so all rows, columns, and diagonals match the target.

How generator works (simple + correct):

  • Starts from a correct base magic square.
  • Applies rotations/reflections (still magic).
  • Shifts every cell by k so the new target sum is reached (still magic).
  • Removes some cells based on difficulty.

Important: for integer puzzles, Target Sum must be divisible by the size (3 or 4).
