How to play
You complete Magic Square Puzzle when all cells are filled exactly once and every row, column, and main diagonal totals the same magic constant. The full Magic Square Puzzle position determines the outcome; visual shortcuts never replace the documented Magic Square Puzzle terminal rule.
- Magic Square Puzzle begins with a partially filled square grid, a tray containing each unused value once, and the required magic constant derived from the full value set. The Magic Square Puzzle deal identity and Normal magic-square placement rules v1 are stored together. Restarting Magic Square Puzzle reproduces this opening exactly.
- During Magic Square Puzzle, you place an unused value into an empty cell, move it to another vacancy, or return it to the tray while duplicate usage is rejected. The Magic Square Puzzle engine rejects profile violations, unavailable material, and every action attempted after Magic Square Puzzle reaches a terminal result.

Strategy tips
- A reliable Magic Square Puzzle plan is to use line deficits and the centre's structural role to narrow candidates, then pair complementary values around the grid. A Magic Square Puzzle hint is legal and deterministic. The next Magic Square Puzzle hint exposes one bounded action; it never claims a forced Magic Square Puzzle win.
- A costly Magic Square Puzzle mistake is to verify rows and columns but omit one main diagonal, or reuse a value whose duplicate makes the sums appear correct. Undo supports studying that Magic Square Puzzle decision, while restart preserves the original seeded Magic Square Puzzle opening.
- In the Magic Square Puzzle endgame, solve the intersection shared by the final incomplete lines and confirm the remaining tray value satisfies every crossing total. Check every remaining Magic Square Puzzle action before committing because its terminal rule is enforced immediately.
