What "chess960" means in chess

Chess960, also known as Fischer Random Chess, is a chess variant invented by former World Champion Bobby Fischer. In Chess960, the starting position of the pieces on the first rank is randomized, with some restrictions to ensure a balanced and strategic game. There are 960 possible starting positions in Chess960, hence the name. The aim of Chess960 is to eliminate the advantage that comes with memorizing opening sequences in traditional chess and to promote creative and original play. The rules and movements of the pieces in Chess960 are the same as in traditional chess.
