Peg Solitaire

Jump a peg horizontally or vertically over one neighboring peg into the empty hole beyond it. The jumped peg is removed. Leave exactly one peg in the center, marked ＋. Diagonal jumps are not allowed.

Tap a peg, then a highlighted landing. Keyboard: use arrow keys to move focus; Enter or Space selects; Escape clears selection. Undo restores your previous jump. Suggestions show a legal move, not a solution. Changing difficulty restarts the board. Progress lasts until this player is reloaded.
