Pegs

Jump a peg over a neighbouring peg, up, down, left or right, into the empty hole just beyond it. The peg you jumped over is removed. Keep going until only one peg is left.

With a pointer, drag a peg to the hole two cells away; the jump is allowed when there is a peg between and the hole is empty. A cell with neither a peg nor a hole is an obstacle, not part of the board.

With the keyboard, arrow keys move around the board. Enter or Space on a peg makes it ready to jump; an arrow then jumps it that way if it can, and Enter or Space again cancels. Ctrl or ⌘ Z undoes; Ctrl or ⌘ Shift Z or Ctrl or ⌘ Y redoes.

If no jump is left and more than one peg remains, the game says so: Undo, or Restart. Undo and Redo follow your history; a new move after Undo replaces the undone moves. Restart returns the board to its start and can be undone. There is no hint or Solve.
