Object of the Royal Chess game is to CheckMate the opponent's King and/or any 'Royal' Piece!

'Royal' Piece is a piece which under a 'Check' attack can be CheckMated.

'Royal' piece can be attacked only by a [Non] 'Royal' Piece, or a 'Royal' Piece that does not come under attack itself while attacking!

In Royal Chess game all Pieces are 'Royal' [Pawns [PPawns] are not]!

In [Non] Royal Chess game Variant all Pieces besides King are 'Royal'.

Try to beat 'Zillions Engine' on this one!

Have fun & Enjoy!
