Check for all click events

Hi,
I am fairly new to JQuery and have been asked by my manager to implement the flip plugin into one of our on-line courses.

I have got the 'flip' code working fine, and have a number of tiles that get flipped (like this).

My question is, how do I know when a user has flipped each of the tiles? I can't just do a count as they could click on one tile multiple times.

Can anyone help?

Thanks
