Genius Tennis

A two player game played on a grid of 42 holes, 7 in each of six rows. The holes in the four central rows have point values of 10 20 and 30, the nearer the centre of the array the greater the value. Each player starts with 20 pegs in the three rows nearest him, the centre two holes remaining empty. Pegs move by jumping over adjacent pegs as in Solitaire, and the jumped pegs are removed. My game rules don't tell me when this process stops! At the end of the game the players add up the value of the holes in which they have pegs and the greatest total wins.
