A jigsaw puzzle. This is the original game which inspired my jigsaw tutorials. This is the same version you can find on Amazon Appstore, Chrome app store or Firefox App store, with some minor last-minute retouches.
Start selecting the image and piece set you want to play with. Then, click on the "scramble" icon on the lower part of the screen (the one with the shape of four jigsaw pieces) to start playing.

1.4.1.1 Update (2015/10/04)
Improved Scrolling - I hope this makes game easier, but I'm unsure.
Fixed 12x8 piece borders - Now they don't have a spurious line.
Fixed winner message - Completion time is displayed properly now.
Added button hints - They are displayed for 5 seconds on the first 7 seconds.
(I can't add "hover" hints since I want touch compatibilty).
