Electromagnetic game board
An electromagnetic game board includes a configurable grid of electromagnets under a game board to move game pieces on the board. Alternative to electromagnets is acoustic levitation through soundwave. In an oscillating electric field (four sides), a magnet can create excite ultrasound that quickly contract and rebound its original shape to push out pulses of air.
