Your spectator is handed a metal domino with moveable magnetic spots. They move the spots around until they have created their own domino.

You then introduce a wallet with four blank cards inside. You use the cards to tap the tile that the spectator made and one of the cards now matches their tile. The other cards remain blank and everything is examinable.

Manufactured in Hungary by Joker Magic. You get a metal Domino tile with moveable magnetic spots, four plastic wallets with the necessary cards and written instructions.
