Puzzlation creates puzzles using patches of colors. The colors at the edges of two adjacent pieces must match. In "Corner Match", the colors span the corners of four adjacent pieces. In "Edge Match", the colors only span 2 edges, giving you less information about the colors of adjacent pieces (resulting in a more difficult puzzle).
Games can be played as regular puzzles - where any two pieces can be swapped - or in slide mode, where there is an empty space and you must rearrange pieces by shuffling them.
After solving a puzzle, challenge a friend (or rival!) to beat your time with an "email challenge". The exact puzzle is sent to the person in an email, along with a link to the free version of the app in the App Store, which they can use to open and play the puzzle. When they complete the puzzle, they will be informed if they solved it faster, slower or about the same as you did. (It is left up to them if they want to share the result back with you…)
Puzzles are dynamically created, so you will never run out. Choose from 6 built-in color schemes for variety, or import other color schemes of your own creation (using the Pattern Artist app).
