Brainvita (also known as Peg Solitaire) is a classic single player board game.
It consists of a cross shaped board, with 33 spots
where marbles can be placed. The starting position
has all the spots filled except for the center spot.
In each move, you can jump one marble over another
marble and land on an empty spot. The marble that
you jumped over is removed from the board, creating
an additional empty spot. You can only jump
left, right, up or down. Diagonal jumps are not
allowed.

The game ends when you are not
able to make a new move. The less the number of
marbles left on the board, the more you score.

There are 32 marbles placed on the board, and the center slot is left empty.

Example Move

You take the highlighted marble and jump over the marble right below it, moving
the marble to the center empty spot. The marble that you jump over is removed,
and you end up with the board on the right, with two empty spots (highlighted).

Game Ending

The game ends when there are no two marbles adjacent to each other. The number of marbles
remaining determines the score. In the below map, there are 4 marbles left, so
you score 2 points.
