Smart Marbles is an iPhone6 app for marble solitaire.
The game is simple: select a marble and then select an empty space in the grid that is two spaces over. Another marble must be placed between the selected marble and the destination space. Once the marble has jumped over the middle marble, the middle marble will be taken off the board.
The object of the game is to remove all marbles except the last. Use the reset button to return the game to the original marble positions.
