From Too Lean Design:
Test your memory and eye-finger coordination with Flipped, an unique new matching game perfect for fans of logic and memory puzzles with a little twist of action.
Your goal is to clear deals of double-sided tiles by selecting matching faces as quickly as your memory and finger fitness allow. In every deal there is at least one set of matches that you can puzzle out for a clean clear. Finding the right matches won't always be easy, though. You'll have to contend with more and more tiles, including some with concealed faces. Fortunately, you'll sometimes be able to take a shortcut with a wild card or multi-tile match.
It's easy to learn to play Flipped. Simply tap a tile to select its visible face or touch a tile and drag your finger sideways to flip it and select its hidden face. You can also flip all unselected tiles by shaking your iPhone or iPod touch. Should you get stuck, touching a tile and dragging up or down will discard it and deal another.
I hope you'll find Flipped Lite an elegant and pleasantly addicting game. Enjoy!
