There are two basic problems with the game.
1. The AI isnt very smart. It makes illogical decisions when bidding and passing cards.
2. The biggest reason for the 1 star rating. I just played 10 straight hands and the computer team got a double run WITH a double pinochle 7 consecutive hands! How is this possible?
Fix the "randomness" of the game and it would be fun; otherwise, its just a time killer.
It would also be improved dramatically if they would incorporate a multiplayer aspect as well. Maybe something similar to poker where people can join a table as either a single or as a team. In this scenario, you could eliminate cheating by filtering on the IP addresses of the players.
