I should probably know cribbage, with as many card games my family played as a kid, but, alas, I do not.  The UI was polished and clean, but basic instructions would have been nice.  I'll give this a try again when I know how to play.  It looks very good in terms of a computer version of cribbage!

It seems like a good base to build on, lots of opportunity to add animations and flourishes. I have no idea how to play cribbage so I was just clicking randomly :)

I don't understand much about gambling but it looks pretty good for a mobile application
