The Chess Board of 64 squares has the following modifications for Blind and Visually impaired chess players :

1. All the Black squares are raised about 3-4 mm above the white squares. By feeling the squares, the player is able to determine whether the square is a black or a white one.
2. Each of the squares on the Board has a hole in the center so that the pieces can be fixed in these holes.
3. Each of the pieces has a downward projection (nail) at the base, which fits into the hole in the squares on the Board, thereby fixing the piece securely on the board.
4. All the Black pieces have a dot fixed on their heads helping the player distinguish between a white and a black piece.
5. Braille notation is indicated on every side of the Chess Board.
