Chess on the Dot is a chess variant invented by Joshua Chao in 2010, which uses a total sphere (not a sphere-like cylinder) as chessboard with standard rules of chess. The digital version of “Chess on the Dot” won red dot design award (Germany) in 2010.
All rules of chess can be applied to Dot without change because the surface of Dot is essentially a 2-dimensional membrane (without borders), and all squares on it can be displayed as a 2-dimensional, flat and rectangular chart with correct relative positions.
The chessboard-dot transformation.
Dot is transmogrified from the traditional, flat chessboard by the following three steps:
1) Connect east and west borders.
2) Cover north and south ends.
3) Squeeze and bulk it up to a sphere.
