I play rummy irl and I am a legit semipro. With that being said I find every difficulty a joke. Every difficulty below expert is easy. And expert is unrealistic. The computer will deal you doubles in a crazy unrealistic amount. There are over 50 cards in the deck first round i should not have 3 doubles in my hand and then pull doubles as well, it's statistically unlikely. Most games on expert you will find your opening hand with 2 to 3 doubl or half (if not more) of your first draws r doubles.
