Marble Solitaire Classic

This is a traditional board game that is played alone, consisting of marbles and a wooden board. It is also known as peg solitaire or brainvita and the most common variations of this game are included.
To play the game you have to take one marble and jump it over another, into an empty hole. The marble that was jumped over is then placed on the outside of the board. You have to keep doing this until there is only one marble left.
You can only jump horizontally and vertically on all the boards except from the triangle, where you can also jump diagonally. You must think ahead to solve the puzzle and try not to leave any marbles unreachable.
