Based on Woo Kok Tang's Big Two for Palm, but I rewrote it from scratch.
The rules are slightly different from that version.

Update Description:
version 1.10 adds the option of comparing highest card on a flush, the option to have the winner start, and turns the "last card" pink.

Great game! Atty needs more practice, try to beat it! Nothing is fair in the real world, what are you gonna do so what they gang up, winners always win by themselves!

Great job. In responding to an earlier comment. I actually like the AI a lot. Once I have gotten used to the computer players ganging up on me, when I play with real people, I usually win. It takes practice but once you get it, you almost never lose to people.

One of the worse ones out there. AI is a bit poor. seems like all 3 guys are gang-up against you. All of them NEVER pass on you if they have a bigger card. Say you throw the 2 of hearts, if anyone of them has a 2 of spades, they will definitely throw to get you. On the contrary if one of them throws the 2 of hearts, the other AI will pass even if they have 2 of spades.

Very realistic and enjoyable. Don't need to find 3 other people to start a Big Two game ever again.
