Triangular Peg Solitaire
Jump one peg over another into an empty spot, which removes the jumped peg from the board. The goal is to finish with one peg.
You can jump along any of the three directions parallel to the outside edges of the board.
Just click on a peg and if there's a jump available, the peg will jump. If there's more than one jump available, you'll need to click on a destination.
The game is over when no more jumps are possible. You win if there is just one peg remaining.
