On this website, you will need to enter what vocabulary you want to practice into the search box.  For example, if you want to practice the days of the week, you would need to type "Spanish days of the week," or if you wanted to practice calendar questions, you would need to type "Spanish calendar."  Also, I recommend that when you are ready to select a game, right-click on the title of the game and select "open link in a new tab." If you don't do this, you have to retype your topic each time in the search box.
