I like this game except it has a scoring bug. For example, I just finished a hand where I did not take a single trick and the score showed as zero throughout the game but then when it showed the final tally for all the players suddenly I had 26 points added for the one hand. The same can happen to other players if they have 0 also, but not every time. It really detracts from playing when you know the scoring can be wrong, I wish they would fix this.
Another thing is even in Hard mode it is easy to get the Jack of Diamonds. Subsequent players tend to play low the same as they should for other suits, even if playing high would allow them to take the trick. Similarly, I am often passed a very high Diamond, again in a manner similar to other suits but this should not apply to Diamonds.
Otherwise, I would rate 5 stars.
