A picture, cut into tiles and shuffled. Swap tiles around until the image comes back together. All the pleasure of a jigsaw, without any pieces to lose under the sofa.
The picture is divided into a grid of tiles and shuffled. Tap one tile, then tap another, and the two swap places. Keep swapping until every tile is where it belongs and the picture is whole.
Note that this is a swap puzzle, not a sliding-block puzzle. That distinction matters more than it sounds. In a sliding puzzle there's one empty space and you can only move tiles adjacent to it, which means getting a tile across the board takes a long convoluted sequence of moves — and it's why sliding puzzles frustrate so many people. Here, any two tiles can swap directly, no matter how far apart. If you can see where a tile belongs, you can put it there in one move.
You can look at the goal image at any time — tap it to enlarge. Doing so isn't cheating and isn't discouraged. Working out what the picture is meant to be is the actual puzzle; memorising it is not.
Random swapping does eventually finish a board, but it's slow and unsatisfying. The approach that jigsaw solvers have used for a century works just as well here.
Before touching a single tile, enlarge the goal image and take it in properly. Where's the horizon? Which corner is darkest? Is there a big block of sky, or a face, or a strong diagonal? Ten seconds of looking saves several minutes of swapping, because from then on every tile you see means something.
The four corner tiles are the easiest in the puzzle. Each has two straight outside edges meeting at a right angle, and there are only four of them. Find them, place them, and you've anchored the whole grid.
Edge tiles have one flat outer side, so they're easy to identify and there's a limited number of them. Work your way round the border. When the frame is complete you've usually done a third of the puzzle, and everything left is a smaller, better-defined problem.
Now go for whatever stands out: a face, a bright flower, a window, a boat, a patch of strong colour against a plain background. These tiles are unmistakable and each one you place gives you neighbours to work outward from.
Big stretches of sky, sea, sand or grass are the hard part of any picture puzzle, because the tiles all look nearly identical. Leave them until the end — by then most positions are already taken and you're choosing between a handful of options rather than dozens.
Sky is almost never one flat colour. It's deeper at the top and paler near the horizon, and once you start looking for that gradient the "identical" tiles sort themselves into rough bands. The same is true of sea, sand and shadow. Trust the slight differences — they're real.
Any line running through the picture — a branch, a roof, a fence, a shoreline — has to continue across the tile boundary. If a line stops dead at the join, the tile is wrong, however plausible its colour. This is the most reliable check available and it costs nothing to apply.
Two tiles can be the same green and still be obviously different once you notice one is smooth and the other has leaf detail. Grain and texture distinguish tiles that colour alone won't.
If you know exactly where tile A belongs, swap it there even if you have no idea about the tile it displaces. The displaced tile is now a new problem, but it's a smaller one, and you've locked in a certainty. Trading a known for an unknown is nearly always a good deal.
The hint button will place a tile correctly for you. Hints cost coins, which are shared across every Calm Game — so play anywhere on the site funds a hint here.
A hint on a plain area is particularly good value, since it's the one place where being stuck is a matter of tedium rather than difficulty.
There's something particular about rebuilding an image. A word game gives you a small reward for each correct answer; a picture puzzle gives you a growing thing you can see. Halfway through, the picture is visibly half-there, and that visible progress is quietly motivating in a way that a list of solved clues isn't.
The thinking involved is spatial rather than verbal — rotating shapes in your head, comparing edges, judging how a fragment fits a whole. That's a different mode from the one the word games use, and a pleasant change if you've spent all day reading.
Like Memory Match, it involves no text at all, so it works for anyone regardless of what language they read in, and it's comfortable for people who'd rather not be tested on vocabulary. And because every swap is instantly undoable, it's the most forgiving game on the site — there's no state you can get into that you can't get straight back out of.
