Polarity: Magnet Puzzle

One tap. Every piece moves at once.

Touch a cell and it becomes a magnet. Blue pieces are pulled toward it. Red pieces are pushed away. Everything slides at the same time and keeps sliding until something blocks it — a wall, another piece, the edge of the board.

Your job is to land every piece on its own target. The catch is that you cannot move one piece without moving all of them.

500 LEVELS ACROSS TEN IDEAS

The game teaches itself. Chapter one is attraction alone. Then red reverses the rule. Then rusted pieces refuse to move at all, coils flip a piece's polarity as it passes, the edges of the board stop being edges, gates read a piece's colour before letting it through, portals connect two cells, and latches stay shut until a target is filled.

Ten chapters, fifty levels each, and every mechanic is introduced on a board small enough to understand it.

EVERY PUZZLE IS PROVEN

Not hand-placed and hoped for. Every board was built by exhaustively searching the space of reachable positions, and each one is then solved again independently to confirm three things:

• It is solvable.
• The stated par is the true minimum — no shorter solution exists.
• Exactly one opening move leads to that minimum, so there is one right answer rather than four that happen to work.

Each chapter's mechanic is also deleted and the level re-solved. If the puzzle still works without it, the level is thrown away. Nothing is decorative.

WHAT ELSE IS IN THERE

• A daily challenge — one board per date, the same for everyone, with a streak
• Endless mode after the campaign, generating fresh boards on your device
• Undo and restart, always free, always unlimited
• A hint that shows the next correct move when you are properly stuck
• A live legend explaining every piece and tile, in motion

BUILT TO BE LEFT ALONE

No account. No sign-up. No server. It works with no connection at all, on a plane or underground, and it does not contact anything — there is no analytics, no tracker, and not even a font request leaving your phone. Your progress lives on your device and nowhere else.

Puzzles, not chores. There is no energy meter, no timer and nothing that expires while you sleep.
