Peggy is a Peg Solitaire game for the iPhone and iPod Touch. This seemingly simple game has hidden depths, and has, through the centuries, attracted the interest of mathematicians from Leibnitz to Berlekamp. Several board configurations exist. This version uses the English board, which is the most well known.
The game starts with pegs in each position except the one in the center. To play, jump a peg over a neighbor along the horizontal or vertical to an empty hole. The jumped peg is removed. The game ends when no more plays can be made. The objective is to remove all the pegs but one. In a perfect game, the one remaining peg is in the center.
