Does anyone know where I can find an online version of 3d chess? This is chess with the board at different levels of height. The game incorporates spacial thinking insted of on a flat board.

Thank you.

No, but you might start by looking at This other website which contains details of hundreds of chess variants. This is just their top-level menu ...

• Three dimensional chess variants: Star Trek and others
  
• Hexagonal chess variants
  
• Round boards
  
• Other boards with an unusual shape
  
• Oriental chess variants: Xiangqi (Chinese Chess), Shogi (Japanese Chess), variants, other oriental chess variants.
  
• Historic chess variants: The first predecessor of chess: Chaturanga, Shatranj, and other chess variants from ancient times.
  
• Multi player variants: Chess with 3, 4, 6, 7 or any number of players.
  
• Small chess variants: Chess on board of size 4 by 8, 6 by 6, etc.
  
• Large chess variants: Chess on boards of 9 by 9 or larger.

I know it's not what you're looking for (ie. the chess featured on Star Trek), but apparently some people have modelled a working version of 3D chess here that I've been looking at:

My brain can't handle 2D chess let alone this, but I'd love to hear what some of the NMs here make of it.

Thank you.

I am seeking a virtual online, player to player version.

I am having tribble finding such a site.

A great chess variant:

Cylinder chess!

All pieces can move from a-file to h-file in one move, even if there is a piece on the b-file! Knights are very special in this variant.
