Rotorblades Chess is a cross between Circular Chess and Trigonal Chess. The name of the game is inspired partly by BLADES (an earlier trigonal game invented by Graeme C. Neatham). The triangular cells are blade-like in shape, and the circular shape of the board as a whole is reminiscent of rotorblades. Apart from a few games by Graeme Neatham and a couple of applets by Christian Freeling, trigonal boards seem little explored, and this is my modest attempt to make a contribution in this area.

Rotorblades Chess attempts to extrapolate the movements of familiar chess pieces to the circular/trigonal board, and also introduces a number of new pieces, some deliberately invented to exploit the unique topography of the board.
