The Cribbage Calculator is for those hands with so many combinations that your head hurts!
Tap the cribb card first and (optionally) its suit, then add four more cards. Always tap the card followed by its suit. Tap "=" to see the score, "x" to delete a card/suit.
A breakdown of the hand appears at the top on taller iPhones. The breakdown only can be seen by tapping the "i" button on older iPhones.
It *does* calculate flushes, however if you choose not to enter suits to save time, it won't calculate flushes (or nobs, for that matter).
