WAN is a child friendly educational card game that can be used to teach the concepts of trigonometric functions and identities or can be played as a simple card game by anyone over seven years old. The game uses all six basic trigonometric functions and their squares. These trigonometric functions are represented by various shapes and colors on the cards. Mathematical operations are determined by how the cards are placed. The game is played by creating card hands representing functions and operations that equal the number one. These card hands are called WAN hands.

To achieve an information output device in which information of a medium disposed on a stage surface can be surely and efficiently read out, and a stage effect and a security are high. In the information output device, media are disposed on a stage surface in a state where the media are opposite to the stage surface, the media where dot patterns are printed on medium surfaces on the basis of a predetermined rule, the dot patterns are read by imaging units disposed in a space below the stage and converted into code values or coordinate values indicating the dot patterns from photographed images obtained by the imaging units, and information corresponding to the code values or the coordinate values is outputted. Further, light transmitting reading holes are respectively provided at a plurality of medium disposing locations on the stage surface, and the imaging units are disposed in the space below the stage corresponding the respective reading holes such that the imaging units photograph the medium surfaces of the media disposed on the reading holes.

A card game comprising cards that contain indicia of a numerical digit from 0 through 9, or ‘W’ representing a wild function, printed and centered on all four-card edges. Some cards have duplicated digits in either opposing or adjacent positions. Other cards contain numerical or ‘wild’ sequences. Indicia are centered at the edges to card matching whereby the indicium may match and align with the indicia on other cards. Indicia calculate the play score based upon what does and does not match. All card corners contain a grouped visual representation of the four indicia on the edges so that a card's layout is legible regardless of its orientation when held in a fanned manner. Players complete the square 16-card playing area first and then continue to play atop the existing cards in separate board sections. This dynamic constantly changes the scoring landscape and requires a fluid strategy to manage.

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.

A deck of cards includes eighty four playing cards. Each playing card has a front surface and a back surface. The front surface of all of the playing cards has the same design. The eighty four playing cards include four sets of twenty one playing cards. Each of the four sets corresponds to a branch of military service and each playing card within each of the four sets of twenty one playing cards corresponding to a rank within a respective branch of the military service
