• Choose a grid size (3×3, 4×4, or 5×5).
• Select a value range or use the random range.
• Drag a tile onto another tile to swap them.
• Every row, column, and diagonal should match the target sum.
• Use Solve to watch step-by-step swaps.

Classic 3×3 magic squares sum to 15, but this version generates new ranges and targets for larger grids.

Swapping tiles keeps the same multiset of values, so the target sum stays fixed for a given puzzle.
