text: Gameplay Within the game's main "Adventure" mode, Peggle is divided into fifty-five levels. Each level features an arrangement of approximately one hundred blue "pegs" positioned to correspond with the level's background picture, inside of three walls on the top and sides (leaving the bottom opened), along with other fixed and moving features. The goal of each level is to clear the board of the twenty-five random pegs that are turned orange at the start of the level, by using a ball launcher located at the top center of the screen to strike one or more of the pegs. Pegs light up when hit, and once the ball either falls through the bottom of the screen or is caught by the ball catcher that moves back and forth along the bottom in a fixed manner, the pegs will be removed. Struck pegs are also removed if the ball is stuck on them. The player begins each level with ten balls (twelve on the non-Touch iPod version) to clear the orange pegs but may earn more by landing the ball in the ball catcher or earning high scores on single shots. Failure to clear the board with the allotted number of balls will require the player to restart the level while completing this objective will allow the player to progress to the next board.
  Every five levels in the Adventure mode correspond to playing with one of ten "Peggle Masters" cartoon characters that help the player. Each of the Peggle Masters has a unique special ability that is activated when the player strikes one of the two randomly selected green pegs on the board. Some activate immediately; one causes a second ball to be generated from the green peg when struck. Others will have effects that activate on the next shot or for several more shots; one shows the ball's path, including rebounds, while another will extend the length of the ball catcher. In the final five levels of the Adventure mode, called "Master" levels, the player can select which of the Peggle Masters they want to use.
