I highly recommend this game, which has given me countless hours of entertainment. I learned tichu from this app (and its still mainly how I play), although Ive managed to introduce it to people with a real deck.
One gripe I originally had with the game was with the AI, specifically the AI partner. My girlfriend used to hear me yell expletives at "Becky" all the time. I have largely eliminated the problems by setting her mode to normal play with better intelligence. At times, Im on the edge of my seat expecting her to totally drop the ball, but usually she plays a lot like a good human partner. Every now and then, she even surprises me by playing off cards in complex and creative ways, although I like to think I carry us (yeah my girlfriend is a little jealous of Becky).
Anyway, the game is awesome, and I recommend it for learning the fantastic game of tichu, passing time indefinitely, refining strategy, and playing multiplayer when you cant do it in person.
