In recent work by Beeler and Hoilman, the game of peg solitaire is generalized to
arbitrary boards. These boards are treated as graphs in the combinatorial sense.
Normally, the goal of peg solitaire is to minimize the number of pegs remaining at the
end of the game. In this paper, we consider the open problem of determining the
maximum number of pegs that can remain at the end of the game, under the
restriction that we must jump whenever possible. In this paper, we give
bounds for this number. We also determine it exactly for several well-known
families of graphs. Several open problems regarding this number are also
given.
