"not worth buying if you are serious about spades"
The interface is good with lots of options for customizing
Plays very poorly and wins by cheating. Most computer card games use this approach. The programmers are either too lazy or too stupid to make the game play for real. The cheats are subtle - like giving you a nil hand when your partner can only bid 1 or 2. Your opponents almost always have a high bid to go with a nil. Your opponents also get bonus scores if you allow a 10 bid bonus of 100 in the scoring settings.
If you are not a good player you might enjoy this.
