Just came across this web site from the Bicycle Playing Card company that clearly and succinctly explains the rules of Cribbage.
I get many emails from users claiming that Quick Cribbage isn't scoring correctly. In all but one recent case it was a misunderstanding of the official rules of Cribbage. Quick Cribbage has been available in multiple forms for the last 30 years and has been well tested. Whether you're a beginner or long time Cribbage fan it always helps to review the official rules.
If you truly believe you have uncovered a scoring anomaly then please attach a screen-capture that shows the error with your feedback. That helps me a lot.
