Picture

The exact count depends on the picture’s shape, so the pieces come out close to square. Your own photo is opened by your browser and never uploaded.

Drag a piece onto its neighbour and it clicks into place; joined pieces move together. Drop a piece near its spot in the frame and it stays put. Edges only puts the middle pieces aside, Picture shows the finished picture, and Guide shows it faintly in the frame. To zoom, use the buttons, pinch with two fingers, or hold Ctrl and scroll; drag the empty mat to move around.

How to play

Choose a picture and a number of pieces. The pieces are cut with the classic shape, a knob (the tab) or a hole (the blank) on each side, and scattered round an empty frame. Drag any piece next to the one it belongs with: when the shapes and the picture line up, they click together and from then on move as one. Drop a piece or a group close to its own spot in the frame and it locks in place there, so you can build the puzzle where it belongs. The timer starts with your first move and pauses while the page is in the background.

The method most people use on a real puzzle works here too. Turn on Edges only, build the border (the pieces with a straight side), then fill in the parts of the picture that stand out, like the red of the plasma cutter or the lettering on the saw, and leave plain areas until last. Our lesson how to do a jigsaw puzzle explains each step.

How many pieces?

24 to 48 is a quick puzzle and suits a phone or a child. 96 to 150 takes a while on a laptop or tablet. 216 and 300 are best on a big screen, ideally in full screen, with the zoom buttons to look closely. The more pieces, the smaller each one is, so on a phone the bigger counts are fiddly.

Is my photo uploaded anywhere?
No. Your browser opens the photo and cuts it up on your own device; there’s nothing on our server that could receive it. So the puzzle survives a reload, a smaller copy is kept in your browser’s own storage on this device. Starting a puzzle with one of our pictures doesn’t remove it; clearing this site’s data in your browser does.
Will it remember where I was?
Yes, in the same browser on the same device. Close the tab and come back later, and the pieces, the joins and the time are where you left them. A private or incognito window forgets everything when it closes, and a very large photo can be too big for the browser to keep (the page tells you if so).
Can I play on a phone or tablet?
Yes. Drag pieces with a finger and pinch with two fingers to zoom. A small piece is easy to miss with a fingertip, so the puzzle picks up the nearest loose piece when you touch close to one. On a phone, 24 or 48 pieces works best. To scroll the page, touch outside the green mat.
Can I play with a keyboard?
The buttons, the picture choices and the piece count all work from the keyboard, but moving the pieces needs a mouse, a trackpad or a touch screen. We know that leaves some people out, and we’d like to add keyboard moves later.
Where do the pictures come from?
They’re our own photos: four our director took during his engineering trade course and his own projects (plasma cutting, a pair of toolmaker’s clamps, a motor cooling rig he built, and a carpentry job on a mitre saw) and one of the multimeter kit from our electronics bench. The clamps are mostly grey steel, which makes that one the hard puzzle.
What do Spread out and Guide do?
Spread out lays the loose single pieces out again round the frame, which helps when they’ve ended up in a pile. Guide shows the picture faintly inside the frame, so you can see where a piece goes. Leave it off for a proper challenge.
