Super Chess 16x16 is a chess variant played on a 16×16 board — 256 squares, four times the playing area of orthodox chess. It keeps the six pieces you already know (King, Queen, Rook, Bishop, Knight, Pawn) and adds five new ones: the Prince, the Princess, the Archbishop, the Super Knight, and the Fortress.
The part nobody else has: every piece is reprogrammable. Before or during a game you can teach a piece new moves by clicking squares on the board. Your Knight can move differently from your opponent's. It is Patent Pending technology, and it is free to play right here in your browser.
Pick your own piece colors and board colors, play the built-in bot at the level that suits you, and when you are ready, sign up to challenge other members.
