Rules are provided for five jumping and number games, four categories of jumping and number puzzles to play on the 6x6 grid. Activities with chess knights' moves and magic squares are especially interesting. A major section is devoted to Wade Philpott's "Leap Solitaire," cited in Oxford University Press' The Ins and Outs of Peg Solitaire. The 36 numbered pieces reverse to blank checkers.
