Pinochle HD has a rule that we never used: after the bidding is complete, the partner can pass 4 cards to his partner. The bidder gets to see them before passing over 4 other cards. Also different: the opening bid starts at 250.
I played Pinochle HD for about 30 minutes. I really like it.....but I'm not sure that the program is people smart. I let the person to my right win the bidding and he picked spades as trump....I had 5 spades including the ace and two tens.
