The Invention: 

A technique utilized in table games using playing cards involves the use of a dealer shoe to prevent players from observing the back of the cards and gaining an advantage during the game. Players sometimes exploit card imperfections to discern the suit and gain an edge. To counter this, the dealer shoe employs an LED panel/bulbs over the back of the first playing card. The light's wavelength, patterns, and intensity are carefully calibrated to minimize optical contrast, making it challenging for players to differentiate colors and/or shapes on the back of the first card and upcoming cards in the deck.



  • Can play more than one deck in the shoe
  • Dealer shoe configured to provide access to and removal of playing cards
  • Light producing element may be derived from but are not limited to: LED panels, LED bulbs, Fluorescent bulbs, incandescent bulbs, semiconductor light emitters
