Think of Carrom as a game of finger billiards. Instead of balls, you use small playing pieces and try to put them in pockets with a heavier piece called a striker. A Carrom board is a large wooden board that contains a variety of markings. Make sure you know the meaning of these markings before you begin to set up the game to play. It's vital to understand the board in order to play carrom effectively.  The Carrom board should be positioned 60-70 centimeters (roughly 23 to 28 inches) above the ground.  A circular hole sits in each of the board's four corners, and a net is placed under each hole to catch the pieces. There are two foul lines on the board, and two concentric circles stand in the board's center. The center circle is the size of a playing piece, and the main circle is six times larger. Before beginning the game, the pieces are arranged in these circles. There are also rectangles drawn on either side of the board. Each player has his or her own rectangle, and must shoot their strikers from these rectangles. There are 9 black pieces in carrom, 9 white pieces, and one red piece (sometimes referred to as "the queen"), in addition to two pieces known as the "striker pieces." Each player has 9 pieces in Carrom, in addition to one striker piece. One player has all black pieces, and the other player has all white pieces. Sometimes, the pieces are referred to as carrommen.  The white and black pieces are smooth, wooden pieces that look something like the ones used for the game checkers. In each round, you attempt to use your striker to knock these pieces into the board's pockets. The red piece is called the queen, and it can be pocketed any time you want after sinking your first piece (the queen's function is similar to the black 8 ball in Billiards). If you have less than 24 points, the queen will add an additional 5 points to your score. If you have more than 24 points, you receive no additional points for pocketing the queen. To start the game, put the queen in the board's center. Then, put six pieces around the queen directly in a circle. Each of those six pieces should touch the queen and its neighboring piece.  Position the remaining 12 pieces around the inner circle of six pieces. Make sure each outer piece must touch the inner circle. Alternate the color of the pieces. In other words, the circle should have one red piece, followed by a white piece, followed by a red piece, and so on. You and your opponent should place your strikers in the rectangular boundaries on either end of the board.

Summary:
Familiarize yourself with the symbols on the board. Learn the significance of carrom pieces. Set the board up for play.
