4D chess

This Saturday, Jay, a teacher in chemistry, came by at our regular chess games in Beijing and introduced his 4D chess game to us. It features some new figures such as the wizard which can go diagonally throughout the space.

It took a while to set up his self build board, but in the end, it was interesting to see the rich complexity of the new dimension. According to him, there is no 4D chess community in Beijing as this format still has to be further explored.
