Link to: Macrochess
Macrochess is a chess variant on a very special board: each of the six sides of a cube has sixteen squares in four by four formation. The board can be rotated.
On the website of Macrochess one can see two pictures of the attractive board, read the rules, read how to order (the game cost US$ 65 plus postage when I checked the website at May 6, 1998), read a newsletter, etc. Since the original link is no more, here it is via Archive.org:
In order to facilitate maintenance of links, separate pages will be made for outgoing links with a small description. Thus, when a link changes, I need to change only one link on one spot. Note that I have no connection to the linked sites. Image used with permission of Macrochess.
