This famous classic board game is known as Brainvita or Marble Solitaire.
The aim of the game is to remove all pawns, except the last one. Can you find the right moves to achieve this?
To remove a pawn, just jump over it with another pawn.
The first levels may seem easy, but they are getting harder gradually to give a sense of achievement for everyone, who play through all the 15 of them.
