QTD-MagicSquares

Gameplay • Goal: rearrange the numbered tiles so every row and column adds up to the target. Diagonals can optionally be included. • Moves: tap one tile, then another, to swap them. Swapping equal values doesn't count as a move. • Levels: Easy uses a 3×3 grid; Medium uses a 4×4 grid and Hard uses a 5×5 grid. • Totals: row, column and diagonal sums show beside the board. They are red until they match the target, then turn green. • Tools: Undo, Redo, Hint and Restart. Each hint counts as a move. • Diagonals: you can include both, only the main one, or none. The Easy level uses the right-to-left diagonal only when the target is divisible by 3. • Timed mode: an optional clock that pauses when the page or window isn't active. Daily puzzle • A date-based challenge, available once per day on the Easy level. • It is always played with diagonals and the timer on. • Solving it extends your daily streak. Scoring • Par: an estimate of the fewest swaps needed to solve the puzzle. • Stars: each finished puzzle earns 1 to 3 stars, based on moves (hints included) against par. • Saved results: moves, hints, par, time, diagonal setting and daily date are stored with each score. Players and history • Profiles: multiple local player profiles, which you can add, switch and delete. • History page: shows all completed games, newest first, plus personal-best moves and best times per level. • Daily streak: the history page also shows your daily streak. • Stars total: the history page shows total stars earned out of the maximum possible, with a percentage. • Reset: history can be reset, with a confirmation. Saving and resuming • Auto-save: an unfinished puzzle is saved automatically for each player, including moves, undo history and elapsed time. • Resume prompt: on startup you get a "Puzzle resumed" prompt, and the timer stays stopped until you dismiss it. • Safeguards: you're asked to confirm before discarding or leaving a game in progress. App UI and extras • Pages: Home, Switch Profiles, Show History, Help, About, Privacy Policy and Other Apps. • Look: a light/dark theme and a card-style layout. • Accessibility: descriptions and hints on the controls.
