The purpose of the vision game mode is to help you develop the ability to memorize and visualize a
full chess game. This will help you visualize games in your mind as you follow along with chess books or PGN data.
Start by reading the PGN game. Once you are confident you have memorized the moves, click the 'Load Board' button and then select the piece that is
misplaced. As the difficulty increases, you will be required to recall longer and longer
sequences of moves.
