MagnetTap – Polarity Puzzle

MagnetTap fills a 5×5 grid with magnetic tiles. Each tile carries a polarity — North shown in magenta, South shown in cyan, or Neutral shown in grey. Tap any tile to cycle its polarity. After every tap the board comes alive: all free North and South tiles automatically slide one step toward their nearest opposite pole, repelled by their own kind. When a North tile and a South tile collide they neutralise each other and both vanish from the board in a flash. Grey neutral tiles sit still and do not react. The goal of each level is to clear every North and South tile from the board through careful polarity flipping that engineers the right collisions. Flipping a tile to the wrong polarity can push pieces away from each other instead of pulling them together, so every tap needs to be deliberate. Faint field lines drawn between nearby opposite tiles give you a visual hint of which pairs want to attract. Fewer taps to clear the board earns a higher score.
