Just played Spades for 1/2 hour. Fantastic work! You did the right thing in allowing the player to jump straight into the game upon landing on the homepage. The games itself are so simple that the process of starting a game should be simple, and you've done that here. Job well done!
Funny thing is that I never play them myself after I've finished them. The interesting part for me is creating the computer player, and seeing if I can make him win more than the human players, I have some stats in Google Analytics that can show me that. Since the computer plays like I would play it's kind of like I'm playing against all the players :)
When I'm testing I usually let the computer just play against itself, add ?autoplay to any of the game urls and when you press Deal you'll see four computer players playing against each other...
