No, it doesn't. It's possible that whatever browser you're using doesn't support some feature, maybe requestAnimationFrame, but I could onlt speculate here. Flash is used for some ads though. I'd suggest you try either Chrome for Android (if on ICS) or Firefox Aurora for Android (the latter is guaranteed to work because both mobile and desktop versions of Firefox have standards support parity).
Disregarding the technical side of things though, the games themselves are below mediocre from a gameplay perspective.
