Date or Pass Game
This game allows you to select "Date" or "Pass" for a random person who's gender you are interested in. After you choose one of the two options, a new girl/guy appears and you get to play again. There is an option to "Let them know", which will notify the person if you chose date. This is a great way to meet new people because if they see that you chose date and decide to message you, then you both know you're interested in each other. With a free account, you can also submit pictures that will automatically be put into this game and you can see who wants to date you. You must be logged in to play.
