Puzzlations: free puzzle app game for iphone, ipad

                       

Puzzlation comes from Kevin Brain (Good last name.)  As you can see from the images, it's an edge-matching puzzle app game.  Here's what's particularly good: you can adjust the settings from easy to hard. Kevin makes a distinction between Corner Match & Edge Match, but they're really the same thing.  When he means Corner Match, he's referring to each side having 2 colors.


Tiles can be swapped. On the harder levels, tiles can only be slid. A lot harder.
