Just been having a play with these free games for fun, they take a minute to load, a look at the instructions is a good idea.

Also see there is some other stuff here as well. Will give the browser a try later on.
EDIT Softpedia on one page gives a warning about the browser and then on another, gives download link
It's that stopbadware.org thing, missed it the other day as I was away on holiday.
