Strato Chess (1973)

The Dynamic Games company first produced a three 8x8 board in 1973 and sold it under the name Strato Chess.
The game board has been widely imitated by many companies since, replicating the boards and stands from the same lucite and aluminium respectively.
In the early twenty first century, it is among the most widely available of all 3D Chess boards, thanks, in part, to the introduction of Millenium Chess.
