Here colonies does not mean the colonies in which we live, but those which were made by the British.
It was called as a colonial sport as well as "The Gentlemen's Game",
As only the colonials or the British used to bat in the game and the rich Indians were allowed to ball. Other Indians were only allowed to field and do nothing else.
They were given wages also.
