In every page that shows a 3D game of chess or check­ers, you will notice that the chess / checker board is mostly clear and is divided into quar­ters. This allows the per­son not to be dis­tracted by the board but assist in play­ing an enjoy­able game being able to see all of the pieces and know where the cen­ter of the board is on both boards.

• Each board is ¹⁄8^th% Black and ⁷⁄8^th% Clear.
  This guar­an­tees the abil­ity to see the pieces below.
• The board is made of a durable plexy glass of ¹⁄8^th inch thick and a
  black vinyl silk screen­ing for the squares printed on the back.
• The 8 squares in length and width: 12 and ¾ inches or 320mm.
• The board is divided up into quar­ters.
  This helps you know where cen­ter is at all times
• White pieces are setup on either Board Level ‘A’ or ‘B’:
