Marble one is Peg solitaire (or Solo Noble) a board game for one player involving movement of pegs on a board with holes. Some sets use marbles in a board with indentations. The game is known simply as Solitaire in the United Kingdom where the card games are called Patience. It is also referred to as Brainvita (especially in India).

Goal: Reach a state where only one marble remains

Rules.

• Find two marbles and an empty location lying together along a line. (that is "marble-marble-empty" or "empty -marble-marble"). This pattern can be in horizontal or vertical direction.
  
  
  
• Select the marble away from the empty location. Then select the empty location. The selected marble will jump over the adjacent one to the empty location (now the pattern will be "empty-empty-marble" or "marble-empty-empty"). The middle marble gets removed by this. Similarly, go on removing the marbles one by one till you reach a state when there are no two marbles together with an adjacent vacant position.
