Agreed, chouette's are great fun and a great way to learn. Unfortunately in my chouette, everyone is similarly unskilled, and so discussions tend to be relatively short, as nobody ever knows the correct answer!
I play under the same rules as Kamba, however the official (I think) rules can be found here:

Enjoy!
