This playing field is a feature of the Star Trek series. In this variant, the Attack Platforms remain stationary throughout the game. Each are considered part of a matched pair, this and their location has been indicated by their colors on the playing field diagram.
 
The remaining pieces begin the game off field. Each player starts the game by introducing their King to their particular Fixed Level. Then each may, in turn, either introduce a new piece to their particular Fixed Level or move a piece on the field.
 
The following is their movement upon the Fixed Level, or to and from adjacent Attack Platforms:
PAWNs step without capture orthogonal or triagonal, step with capture diagonal.
KNIGHTs leap one orthogonal then one forward diagonal, or steps triagonal.
BISHOPs slide diagonal or steps triagonal.
ROOKs slide orthogonal or steps triagonal.
QUEEN slides orthogonal or diagonal, steps triagonal.
KING steps orthogonal or diagonal, steps triagonal.
 
All pieces change Fixed Levels only in the following method:
When a pieces steps on an Attack Platform, it is automatically "transported" to the exact cell of that Attack Platform's match. In this implementation this will be accomplished by an additional move, except for the King who will be automatically "transported". The destination cell of this "transport" should be vacant, but if it is occupied both the arriving piece and the occupying piece are removed from play. This is regardless of the owner of either piece. A piece can make a simple capture when landing on the Attack Platform from the Fixed Level, such will occur as it is sent to the matching Attack Platform.
 
The game is won by check-mating the opponent King.
