I'm a huge fan of card games. Besides bridge, I adore cribbage. Unfortunately it's a game with a bit of a learning curve, and though I have a cribbage board (which came without pegs, so I had to make new ones out of popsicle sticks) I can only play it against the computer.
Here's a nice on-line edition:http://www.freewebarcade.com/game/cribbage/
-you can only play one game, then it messes up and you have to press F5 to play another, so you can't play multiple games to see who's better
-since it is easier to win cribbage if you are dealer first, that's a big difference
-the AI is not hard to poke through: eg if the computer has a 5 and can't make 15 or run, he'll play his 5 last.
It's an OK version nonetheless, but if anyone finds a better one on-line, let me know.
