Scramble

The definitive iPhone version of the classic 15-puzzle, in which you must rearrange 15 scrambled tiles in a square grid. Scramble an image from your photo library or camera, or use a preset image.

There are also several challenge modes:

* Race against the clock: chess prodigy Bobby Fischer could solve the puzzle in 25 seconds -- how fast are you?.
- Minimize moves (every solvable configuration can be solved in at most 80 moves).
- Fade challenge: each tile gradually fades away until you find its correct position.

Also included is the "challenge" for which Sam Loyd offered a $1000 prize in the 1870s to anyone with a correct solution. He caused a puzzle sensation, but not many prize claims...
