How to play

Finish with one peg, ideally in the center of the cross-shaped board.

  • Select a peg with another peg directly beside it and an empty hole beyond.
  • Jump horizontally or vertically into the empty hole to remove the middle peg.
  • Continue until one peg remains or no legal jump is available.

Strategy tips

  • Work the outer arms inward before isolating a corner peg.
  • Keep routes open through the center for the final sequence.
  • Undo after a dead end and compare which earlier jump divided the board.

Rules, scoring, and strategy

Peg Solitaire is a pure move-order puzzle on a cross-shaped board. Every move jumps one adjacent peg into an empty hole and removes the jumped peg; a strong solution finishes with a single centered peg.

The standard cross board

The board begins with every valid hole occupied except the center. A legal move travels exactly two holes horizontally or vertically: the neighboring hole must contain a peg and the landing hole must be empty. Diagonal jumps are not allowed.

Outcome and move count

Each jump removes one peg, so a one-peg finish has a fixed number of moves from the standard start. The game reports a win with one peg remaining and a stuck result when several pegs remain but no legal jump exists.

Avoid isolated arms

A peg stranded at the end of an arm cannot return unless another peg remains in exactly the right position. Work outer pegs toward the center and avoid clearing the central lanes too early.

Plan the final pattern backward

Imagine the last jump landing in the center, then preserve the two positions needed for it. Use undo to study a dead end rather than restarting blindly. A legal hint identifies a move but does not guarantee that every continuation wins.

Questions players ask

Are diagonal jumps legal?

No. The standard cross-board rules used here allow horizontal and vertical jumps only.

What is the best finish?

Any single remaining peg wins this implementation. Finishing in the center is the classic target and the cleanest solution, but it is not recorded as a separate result.

Does every legal move lead to a solution?

No. Many legal opening moves eventually isolate pegs, so move order and future routes matter.
