Note: As of 3/3/2017 the online servers have closed affecting this trophy:
Go down the pinkish purple path (Main Street). On the other side of the street from the theater is another pink portal to Flynn’s Arcade, and go through the portal to the Arcade. Inside the arcade, in the center of the room, are 5 arcade games you can play with other people that are online. Press 
on one you would like to play. You do not have to win the game, simply play until completion. After playing 10 games in the arcade the trophy will unlock.

In the hub world, enter Flynn's Arcade; now go over to an arcade machine and enter matchmaking. Once you've gotten into a game, complete the game and play nine more matches. The achievement should unlock at the beginning of the tenth match.
Note, there aren't a lot of people playing this game. I got this achievement by have two controllers on and playing during the day when kids are playing. You will rarely find matches at night! Alternatively, you can find a boosting partner and try to get into matches with him/her.
