Mosaic Art Puzzle is a free online mosaic assembly game you can play instantly in the browser, with no download and no account. A picture — a sunrise, a tulip, a sailboat, a toucan, a hot air balloon — is cut into small clusters of coloured tiles, and those clusters are dropped into a tray for you to fit back onto an empty board. The finished picture stays visible beside the board the entire time, so this is not a puzzle about deducing what the image is. It is a puzzle about space: which cluster goes where, what shape the hole you have left behind is, and which of two similar-looking pieces is the one that actually fits. Pieces cannot overlap and cannot hang off the edge, so a wrong placement is refused rather than punished, and tapping a piece you have already placed lifts it straight back to the tray. Because every board is made by cutting the finished picture up rather than by generating pieces and hoping, a perfect solution always exists — the test suite verifies for every level that putting each piece back where it was cut from reproduces the picture exactly. You are not required to find that particular arrangement though: any full board whose colours match the picture wins, and pieces of the same shape and the same colours are genuinely interchangeable. Six pictures run from an eight-by-eight sunrise to a ten-by-ten balloon, Recut slices the same picture into a completely different set of pieces, and nothing anywhere is timed.
How to play Mosaic Art Puzzle
- The picture you are rebuilding is shown in the panel beside the board, and it stays there for the whole level. Nothing about the image is hidden from you.
- Tap a piece in the tray to pick it up. It highlights in gold to show it is the one you are holding.
- Tap a square on the board to drop the piece. The top-left corner of the piece lands on the square you tapped, and a white outline previews exactly which squares it will cover before you commit.
- If a placement would overlap something already down, or hang off the edge, the preview turns red and the tap is refused. Nothing is lost and there is no penalty.
- Tap any piece already on the board to lift it back into the tray. That counts as a move, but it is otherwise free.
- Pieces do not rotate. The shape you see in the tray is the shape that goes on the board, which keeps the puzzle about placement rather than about spinning every piece four ways.
- The board is complete when every square is filled and every colour matches the picture. It finishes on its own — there is no submit button.
- A filled square that is the wrong colour is outlined in red, so a board that looks finished but is not tells you exactly where the mistake is.
- Hint takes the next piece still in the tray and puts it where it belongs, lifting anything already in that spot out of the way first.
- Recut slices the same picture into a completely different set of pieces, so a level can be replayed without repeating itself. Reset just clears the board and gives you the same pieces again.
Tips
- Start with the corners and edges. A piece touching the board edge has far fewer positions it can legally sit in, so those are the placements you can be sure about.
- Work from the most unusual colour. If a picture has only a few tiles of one shade, the pieces containing them can only go in one place, and they anchor everything around them.
- Look at the hole, not the piece. Once a few pieces are down, the question is what shape is missing — scanning the tray for that shape is much faster than testing pieces one at a time.
- Single-tile pieces are worth saving for last. They fit almost anywhere, so placing them early gives away no information and can block a larger piece that needed that square.
- Two pieces with the same shape are only interchangeable if their colours match too. When a board comes out full but with red squares, a same-shape swap is nearly always what happened.
- Use the preview outline rather than guessing. It updates as you move across the board, so you can sweep a piece around and watch for the position where the outline goes white.
- If a level is fighting you, Recut rather than Reset. A different cut of the same picture often has an obvious starting piece where the previous one did not.
FAQ
Is Mosaic Art Puzzle free to play?
Yes. It runs in your browser with no download, no sign-up and nothing to buy. All six pictures are there, unlocking in order as you complete them.
How is this different from a nonogram or a picross?
A nonogram hides the picture and makes you deduce it from number clues. Here the finished picture is shown the whole time and nothing is hidden — the challenge is spatial, fitting the cut-up clusters back together without gaps or overlaps. There is no deduction and no arithmetic.
Is every puzzle guaranteed solvable?
Yes, and by construction rather than by luck. Every board is made by cutting the finished picture into connected clusters, so putting each piece back where it came from always works. The test suite checks exactly that for every level and several different cuts.
Do I have to place the pieces exactly where they were cut from?
No. Any arrangement that fills the board and matches the picture wins. Pieces of the same shape carrying the same colours are genuinely interchangeable, so most finished boards differ from the original cut in at least a few places.
Can I rotate the pieces?
No — pieces go down in the orientation shown in the tray. That is deliberate: rotation would multiply every piece by four positions and turn a quick spatial puzzle into a slow search, without making it more interesting.
What do the red squares mean?
A red outline on a filled square means the colour there does not match the picture. It happens when two pieces of the same shape but different colours have been swapped, and it is the fastest way to find the mistake on a board that looks complete.
What does Recut do?
It cuts the same picture into a completely different set of pieces. The image is the same but the puzzle is new, which is how a level stays replayable. Reset, by contrast, clears the board and hands you back the pieces you already had.
Does Mosaic Art Puzzle work on mobile?
Yes. Tapping a piece then tapping the board works the same as clicking, and on a narrow screen the picture and the tray stack underneath the board rather than beside it.
