According to ITTF rule 2.13.1, the first service is decided by lot,[29] normally a coin toss.[30] It is also common for one player (or the umpire/scorer) to hide the ball in one or the other hand (usually hidden under the table), allowing the other player to guess which hand the ball is in. The correct or incorrect guess gives the "winner" the option to choose to serve, receive, or to choose which side of the table to use. (A common but non-sanctioned method is for the players to play the ball back and forth three times and then play out the point. This is commonly referred to as "serve to play" or "rally to serve"or "play for serve") good
