In the past few months, we have covered plenty of unique chess sets. The Vertikal Gravity Chess is a set with a twist. It is a cylindrical magnetic chess board that rotates on a horizontal axis, so your opponent will have to focus harder to make sense of your moves.
The board and its base are made of coated carbon steel. The pieces are machined from aluminum and brass. As the developers explain, Vertikal Gravity Chess is available in manual and electric versions. More info is available here.
