I'v understood game's rules even without big knowledge of geometry (i'm
not sure, but probably some slow on the uptake people can understand it
easier if describe moves like this: orthogonal moves changes 1 line, 2D
diagonal moves changes 2 lines, 3D diagonals changes 3 lines and 4D
diagonals changes 4 lines, orthogonal moves can also be called '1D
diagonals', maybe, geometrician will tell that it's not right, but help
to understand 3 and 4 dimensional chess).
I really, really, really want to play it, but i can play chess only with my
father, and he was not able even to understand how to play 3D game 4x4x4 on
normal board... I am very sorry, that there is no one to play this game
with...
What is next? Game on 8x8x8x8 board? Is there game like this, but in 4
dimensions: http://www.hixoxih.com/games/chess/3D8L.htm ?
Or, at least, game, where pawns moves only forward and king can go 1 step
in ANY direction?
