This freeware game has been around for a very long time, and I've recently just uncovered it thanks to an entire afternoon of Pusoy Dos in pollen-coated Valley Forge and a phone call to my brother about it. In this Hong Kong version (called "Big Two") the suit rankings are a little different, but you'll get used to it. And you can re-order your cards easily by suit or by face value (and thus, by pairs or threes).

So, find that dead and useless Palm of yours and make it your new best friend.
