An authentication method and system includes a computing device, such as a smart phone, which includes a display for presenting a graphical and interactive game board that is used for entering a user's passcode. During the authentication process, the user selects a game board (e.g. chess, checkers, poker, backgammon, etc.) and associated game pieces for presentation on the display. The user then moves one or more game pieces to locations on the game board. Together, the selected game board, selected game pieces, and the movements and/or locations which the game pieces are moved on the game board form an entered passcode. This generated passcode is then compared with a stored passcode to authenticate the user before granting access to the computing device.

The game table reading system comprises reading antennas for each of a plurality of reading areas of a game table, read-restriction antennas for each of the plurality of the reading areas, the read-restriction antennas restricting the RFID tag embedded in a game token placed in the corresponding reading area from being read by the reading antenna corresponding to the other adjacent reading areas, a reading control device that controls the reading antennas, and a read-restriction control device that controls the read-restriction antennas. The read-restriction control device causes the read-restriction antennas corresponding to the reading areas adjacent to the reading areas corresponding to the reading antenna that the reading control device causes to read, in synchronization with the reading control device.

A system having a radio-frequency-identification (RFID) tag reader and a camera to map playing cards to RFID tag values. Each card is inserted into a sleeve that has an RFID tag. During or after insertion of a card into a sleeve, the camera captures an image of the card and the RFID reader captures an RFID tag value for the sleeve. The identity of the card is then determined from the captured image and mapped to the RFID tag value. This mapping information is generated for each card-sleeve pair in a card deck and utilized to track the movement of the cards during game play. The RFID tag value of each card-sleeve pair in the card deck is captured before and after a player draws a card from the deck. The missing RFID tag values are compared to the mapping information to identify which cards where drawn by the player.

Conventional systems have a problem that, after drawing cards onto a table in a baccarat game, if a dealer makes a mistake in dealing cards to the Player side and the Banker side or in passing cards to game participants after dealing, the mistake cannot be detected. An abnormality detection system according to the present invention can detect an abnormality or cheating and issue a warning or stop the abnormality or cheating based on an image analysis result from an image analyzing device 12 when, after drawing cards onto a table in a baccarat game, a dealer makes a mistake in dealing cards to the Player side and the Banker side or in passing cards to customers after dealing, for example.

Automatic card shufflers may include a card input mechanism for inputting cards into the card shuffler, a card storage device for receiving cards from the card input mechanism and temporarily storing cards within the card shuffler, and a card output mechanism for outputting cards from the card shuffler. The automatic card shufflers may randomly select an internal compartment to be an overflow compartment for inserting cards when a failure of insertion of a card to a selected primary card position occurs.

An automated card dealer assembly includes a gaming table that has a plurality of chairs is positioned around the gaming table for having a player sit on the chairs. Each of the chairs is assigned a respective one of a plurality of gaming spots at the gaming table. A card dealing unit is positioned on the gaming table and the card dealing unit contains at least one deck of playing cards. The card dealing unit has a dealing chute that is movably integrated into the card dealing unit. The card dealing unit is in communication with each of the weight sensors and the card dealing unit deals a predetermined number of playing cards outwardly from the dealing chute. Additionally, the dealing chute is actuated to deal the predetermined number of playing cards toward each chair to deal playing cards to each player.

A table game system is provided capable of identifying shuffled playing cards used at the time of the occurrence of a problem in a card shoe apparatus, thereby enabling an investigation of the cause thereof or the taking of countermeasures therefor. A card shoe apparatus of the table game system of the present invention includes a barcode reader and RFID that reads a barcode or RFID provided in a shuffled playing card set, thereby reading a shuffled card ID that uniquely identifies the shuffled playing card set. The control unit has further a function of identifying an exposition of the cut card by the card reading unit and memorizing this information as that the shuffled playing card set now being used will have or be changed to the new one. The information of the exposition of the cut card is at least used for identifying an end of the current game using the shuffled playing cards set is currently set in the card shoe apparatus. A control unit further includes a function of identifying specified events that occur during the use of set of the shuffled playing cards at a game table, and of reporting these occurrences of the specified event in connection with a shuffled card ID.

A method for playing a hold 'em card game with two hands provides a variant to a standard hold 'em card game by dealing four hole cards to a player, and splitting the hole cards into two sets of hole cards, with each set of hole cards being independently played, bet, raised, or folded in relation to the same community cards. An initial round of wagering occurs, followed by dealing four hole cards to each player. The hole cards are split into two sets of hole cards that are played independently of each other. There is another round of betting, before a turn and a river are also dealt. If the dealer's best of five hands exceeds a poker hand ranking of the player's, the player forfeits the wager. If the player's best of five hands exceeds the dealer's, the player receives an equal amount of units to the wager.
