Your goal is to remove all but one pegs (pumpkins) from the board.
You can select any movable (yellow) peg to remove an adjacent peg, by jumping over it horizontally or vertically, to an unoccupied position. You lose the game, if you have only immovable (red) pegs.
Your high score is based on the time you needed to solve the board.
You can switch on/off the automatic board rotation during the game in the Settings Menu, but you can also rotate the board manually.
