I am having trouble getting the Blocks game to operate. The screen opens, but does not allow me to see the "hear" button.

It sounds like you may have your browser window zoomed in a bit which can have an affect on the 3D and cause some elements not to display properly. If you press Control - 0 (the number zero) or Command - 0 if you're on a Mac, that should resolve the issue.
