Where are the pricing games in The Price Is Right 2010 for PC?

I just bought and downloaded the full version of this game from http://www.bigfishgames.com/ this morning and I like it. I have one concern, though. I saw a YouTube video for this game:

Beginning at the 1:30 mark, this user shows all of the pricing games. When I went to that same screen though, I saw that I only have 20 games included and just one page. The games I saw in the video were Double Prices, Check Game and Bonkers, just to name a few. These pricing games aren’t in my game. I thought that all 32 pricing games would be in the selection already. Is there something I can do to get the rest of the games?
