For those who don't know, the normal chess we play every day is 2 dimensions chess. The chessboard is a flat 2D shape, and the pieces also move in two dimensions. But in 3 dimensions chess, additional boards are stacked on top of each other and it looks like 8 chess boards are stacked, so the movement of the pieces takes place in three dimensions. I don’t know exactly how the pieces move in 3D.
