When you read the fantastic you think about parallel worlds and about a teleportation. Bermuda chess was invented especially for amateurs of such strange things.
The 3D board of Bermuda chess consists of two complementary 64 squares boards: classical lower (on the left) with the human pieces and quarter- turned upper (on the right) with the alien pieces. It is from other point of view 64x2 complementary squares boards.
The initial (in agree with etiquette centre-symmetrical) position is follows.

Bermuda chess has several additional rules for moves of chess pieces:
1. If a piece from the upper board moves to a square occupied by an opponent’s piece the latter is captured and moved from own square to complementary square on the lower board. If this square is occupied by any piece the latter is captured and removed from the lower board as part of the same move.
2. Any piece from the upper board can move to complementary free square on the lower board or capture an opponent’s piece on it.
3. It is not permitted to move simply a piece from lower board to upper one. But if a piece from the lower board moves to a square occupied by an opponent’s piece the latter (souteneur) is captured and removed from the lower board. The attacking piece (protégé) continues the move to the complementary square on the upper board as part of the same move but if this square is occupied already by other piece the attacking piece is remaind on the lower board.
4. The king’s rule is entered instead the checkmate: pieces have right to move only when a king of their color is present on the same board. One black and one white kings can be captured without ending the game.

Other rules of this game are identical with rules of classical chess [1].
