Can I make a jigsaw puzzle from my own photo?
Yes. Press Use a photo and pick any picture. It's cut into pieces right in your browser and isn't uploaded. Photos with clear colors and shapes are easiest; a sky or a lawn gives many pieces that look alike.
Do the pieces lock together like a real jigsaw?
Each piece snaps into its own spot in the frame when you drop it close by. Pieces don't join each other outside the frame, so build from the frame inward.
Can I play on a phone or tablet?
Yes. Drag pieces with your finger. On a phone the loose pieces sit below the frame. 12 or 24 pieces suit a small screen best.
Is my progress saved?
Your best time for each number of pieces is kept on this device. A puzzle in progress isn't kept, so finish it before you leave the page.
