From the main menu, select Game Show. You can do this either solo or with a friend and you do not have to win the game shows in order for it to count.
This one should be pretty easy to get, though it'll take a few hours. Keep in mind it's cumulative, so you don't have to worry about doing them all in one sitting. Just keep at it until the achievement unlocks (helps to keep track of your wins either with a piece of paper or with a calculator.)
