The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
What works
Everything but the page rendering, and launching games.
What does not
It seems to use IE for page rendering(iWinGamesHookIE.dll), but my Gecko installation didn't seem to work.
I could not launch the test game(Jewel Quest III).
What was not tested
Signing in.
Anything that could be tested with the page navigation.
Additional Comments
Obviously, the application runs, but is pretty much unusable for anything at this point. So I gave it a bronze rating.
