Triangular Peg Solitaire

Triangular Peg Solitaire

Jump pegs and leave just one: 20 graded challenges plus a full triangular board.

How to play

This five-row triangular board has fifteen holes. Jump an occupied peg over one adjacent peg along a straight board line into the empty hole immediately beyond it. The jumped peg is removed. Jumps follow the three board axes in both directions; there are no extra square-grid diagonals. Leave exactly one peg anywhere to win. If more than one remains and no legal jump exists, Undo or restart. Select a peg and then its empty landing, or drag between them. Leaving the board, opening Help, resizing, losing focus or cancelling a touch clears an unfinished selection without moving a peg. Hole numbers run from 1 at the top to 11–15 across the bottom, matching the example route on the game page. Hint outlines a move from a verified complete route; Play hint makes it. If the current position has no one-peg finish, Hint tells you to undo rather than inventing a move. Undo restores one jump, including after success or failure; hint use is never refunded. Twenty challenges are reachable positions from the full top-vacant board, with nondecreasing peg counts and strictly increasing fixed search work. The full-game mode starts with fourteen pegs and the top hole empty. Solving a full game does not unlock challenges. Mode changes, restart and switching levels ask first. Keyboard: arrows move focus, Enter/Space selects a peg or landing, Escape clears, H Hint, P Play hint and U Undo. Unlocked challenges, best scores and sound save locally when storage is available; unfinished boards restart on reload. No timer or account.
