how to get castle victory


Today I got the castle victory I am just trying from so days but while I am playing today I have won the queen of my opponent and almost I have won but I have thought and I didn't castle with the help of queen and room I have blocked the two sides the king is moving in the centre and I have done the queen side castle move and I checkmate by castle victory the probability is less in number but you should not castle till the end game and you should wait till the end....
