Magic Square
Magic Square
Force any total. A 4×4 square where every row, column, diagonal and more sums to the number your spectator names.
Works for totals 21–9999.
How it works
Start from a base square of 1–16 (which sums to 34), shift every cell up so all sixteen numbers land near the target ÷ 4, then spread the small remainder across four cells. Even a year like 2026 reads as sixteen natural numbers, not four giants among twelve tiny ones.
