About the game
Polar Magnets is a logic puzzle played on a board of domino slots. Each slot either holds a magnet, with a plus half and a minus half, or stays empty. Two plus halves may never sit side by side, and neither may two minus halves, though a plus next to a minus is fine. Numbers on the left and top count the plus halves in each row and column, and numbers on the right and bottom count the minus halves.
Tap a half to drop in a magnet with plus on that side, tap again to flip it, again to mark the slot empty. The twist is that the magnets push back. Put two equal poles together and both halves shudder apart with a buzz, so you feel the mistake right away. Thirty puzzles come in 4x4, 6x6 and 8x8, each with one answer.
