Many of the archived pages are lacking graphics. I will provide links to pages with complete graphics:

I could not find complete graphics for the other pieces. The Bishop page has one graphic image, but it does show an important difference from the Bishop in Chess on the Dot. When passing through a pole, a Bishop may continue its move in either direction, whereas in Chess on the Dot, it must continue its move in the same direction it was going before. The text on the Queen indicates that it moves as a Rook or a Bishop and has the same ability as the Bishop to move diagonally in either direction after passing over a pole. The text on the Pawn page does not indicate anything unusual. It moves as it does in other Spherical Chess variants.

Based on what I could glean of the rules from archived copies of the website, Global Chess is mostly like Chess on the Dot but has a few differences:

  1. Only normal castling is available. If, for example, the white King has a clear path to the a1 Rook in either direction, it can castle by moving to c1 but not by moving to g1. Whereas Chess on the Dot would also allow castling by moving to g1.
  2. The Bishop in Global Chess is more powerful, because it can go in either direction after passing over the pole, whereas the Bishop in Chess on the Dot may only continue in its original direction.
  3. The Knight has only six moves when near the pole, as it does in Miller's Spherical Chess. The extra two moves available in Chess on the Dot (and also in Nadvorney's version) are not shown in the diagrams for the Knight.
