3 Dimensional Cubic Chess 8x8x8 Board

Nah that's weird, only 1 king regardless of the number of dimensions lol

Another interesting question, how many 3d queens needed to control every vacant cube on the board. With 2d we know it's 5 ("The mathematics of chessboard problems" is an interesting read)..

I think the history of this was more just people would play over boards just spread across the table. So 8 boards with all those extra places to move. The link you provided in chess variants was kinda of cool and it warms my heart that people are into that stuff. Of course, 3d chess is actually quite easy to play online tho : https://store.steampowered.com/app/3463010/ChessFinity_Demo/ Where you can play against your friends for free in a medley of different sizes. In my experience and I do play a lot of 3d chess, an 8x8x8 board is just too big , too time consuming and rather confusing without having to use tooling for marking grids and move preview modes being turned on. A comfortable size is around an 8x8x3 with parties staring at the 1 and 3 levels Anyway. Enjoy
