A pad of pins corresponds to each reel in the machine; as the reels spin, the braille display changes under the player’s fingers until the winning combination is displayed. If the player wins, the machine vibrates slightly. Any winnings are credited to the machine until the player presses a payout button. “This will also deter any theft from any other individuals.”
A regular slot machine is modified so that the electromechanical or video slot machine game will interact with refreshing braille pins. Although this machine has a retro look it was patented fairly recently by the inventor, Edward B. Kaplan in 1995.
