There are java based games around that you just play for free in your browser...yahoo do em and so do quite a few other free online game sites.
I googled something like 'free online games' the other day, to try and find browser based card games I could play at work. I found loads, some you will need to sign up for free with an email address, but it's dead easy.
Couldn't play em at work tho...turns out all the clever firewall thingys block java games too...along with gambling, porn, chatrooms, and lots of other fun things....
So I end up actually doing some work.
