American Bingo begins with players purchasing a paper card on which is printed a 5 by 5 matrix of numbers.

In the center of the matrix, a space is designated free. This space is considered filled. The object of this game is to complete a prescribed pattern on the card. This is obtained by covering up numbers as they are called. A caller is responsible for informing participants of the desired winning pattern as well as announcing winning Bingo numbers as they are made available through random selection. Participants who believe their card to have a winning combination must cry out "Bingo!" to alert the organizer that the game may be over.

Human and computer are now able to participate in games, whether to pass the time at home or in the frame of highly organized tournaments, worldwide, featuring prestigious prizes and titles.  

To play chess, it is first necessary to organize the series of game pieces featuring defining characteristics (like colour). Two opponents take charge of their 16 game pieces depicting a monarch's court and 8 pawns. Standing on a traditionally square checkered board measuring 8 squares wide by 8 squares long, each player's queen must rest on its own colour (black/white) on the first and last row. The other pieces are placed in this order: rook, knight, bishop, queen, king, bishop, knight, and rook. The player who's pieces are white begins the game. Pieces are moved to spaces unoccupied or those that have an opponent's piece resting there. In the case of the latter, this piece is captured and removed from the board. Pieces in chess have various styles of movement, intended to ressemble their worldly counterparts (they are listed below). Apart from 3 special moves known as Castling, En Passant and Promotion, the game continues with typical piece moves. To win the game of chess, one may resign in a hopeless situation, a player's king may be put in checkmate or if the particular game has limitations set by other at-hoc rules.

From Wikipedia

• The king moves one square in any direction, the king has also a special move which is called castling and also involves a rook.
• The rook can move any number of squares along any rank or file, but may not leap over other pieces. Along with the king, the rook is also involved during the king's castling move.
• The bishop can move any number of squares diagonally, but may not leap over other pieces.
• The queen combines the power of the rook and bishop and can move any number of squares along rank, file, or diagonal, but it may not leap over other pieces.
• The knight moves to any of the closest squares which are not on the same rank, file or diagonal, thus the move forms an "L"-shape two squares long and one square wide. The knight is the only piece which can leap over other pieces.
• The pawn may move forward to the unoccupied square immediately in front of it on the same file, or on its first move it may advance two squares along the same file provided both squares are unoccupied, or it may move to a square occupied by an opponent’s piece, which is diagonally in front of it on an adjacent file, capturing that piece. The pawn has two special moves, the en passant capture, and pawn promotion.
