cricket at caribbean islands ?

Question

cricket AT caribbean islands or cricket on caribbean islands?whic one is right?also into the blues or in the blues ?which one is right?pls help

Answer 1

I tend to say "in Caribbean islands", although I would not say categorically that "on" is wrong. "At" is certainly wrong.

I don't understand the second phrase, other than in the context of the Blues and Royals Regiment, when one could say that Prince Harry is in the Blues and Royals Regiment. There is also the expression "to have the blues" when one feels despondent.
