Abstract: A portable system and method for identifying roulette wheel biases includes a frame member rotatably attachable to a roulette wheel proximate a turret support, a ball-drop tube slidably engaged to the frame member and a laser positioned to measure at least a bounce height of a roulette ball dropped through the ball-drop tube onto selective areas of the roulette wheel. One or more sensors may be positioned to trigger the laser responsive to a roulette ball being dropped through said ball-drop tube. Software analyzes the bounce height to determine dead spots and hot spots on the roulette wheel. Sound waves may also be measured to determine dead spots and hot spots.

Abstract: A card game is described in which two hands of cards are dealt, and players are invited to wager on whether one hand or the other will win, or whether the hands will tie. The hands may initially be formed from two cards each, and further cards may be added to the hands on the basis of a predetermined dealing tableau. Determination of the winner may be on the basis of a modified blackjack scoring system which provides for a winner even if both hands have totals over 21. In an alternative embodiment, the initial hands are formed from five cards each and the winning hand is determined by determining ascribing a rank value to the five-card combination and determining that the winning hand is the hand with the higher rank value. In some embodiments, the rank value may represent the highest-ranking poker hand which can be formed from the cards of each hand, and the winner will be the hand from which the higher-ranking poker hand can be formed.
