Everything is a card collection game. Editors have created educational and entertaining sets of cards about, well, everything. From the periodic table of elements to the characters in Buffy the Vampire Slayer, there's something for everyone!
Every day, you get a fresh new grid of sixteen cards to flip. If you get cards you already have, or things you're just not into, you can give them to your friends, or cash them in for coins which you can use to buy extra flips. You can mark series as favorites to let your friends know how to return the favor when they get an extra that you need.
