Jigsaw Puzzle

1) Move pieces. The faint frame in the middle is where the finished picture goes. Drag the scattered pieces around it with the mouse or your finger. The piece you hold always comes to the top.

2) Snap together. Drop two neighbouring pieces in the right spot and they stick like magnets into one cluster that moves as a whole. Drop a piece or cluster in its place on the frame and it is locked to the board and can no longer be moved.

3) Finish. When every piece is connected and locked on the board the puzzle is complete, and your time and best time are shown. The timer starts when you first touch a piece and pauses when the tab is hidden.

4) Toolbar. Preview lays a faint copy of the picture on the frame. Edges only hides clusters that have no border piece so you can build the border first. Scatter throws the unlocked pieces around the board again, and Restart starts over with the same settings.

5) Rotation mode. With rotation on, pieces start turned. Tap (click) a piece or cluster to turn it 90° clockwise; moving more than 5 pixels counts as a drag instead. Both the direction and the position must match for pieces to snap.

6) Resume. Built-in puzzles save their progress in this browser automatically, so you can continue from the Resume button on the main screen.

Classic. An even grid with outward and inward knobs, closest to a real jigsaw.

Irregular. Grid corners wobble and every knob differs in size, position and lean, so no two pieces look alike.

Mixed. Each side randomly gets a knob, a wave, a zigzag or a double knob, which makes the shapes useful clues.

Special — Hexagon. Honeycomb-style hexagons. The outer boundary is cut to the rectangular photo.

Special — Triangle. Squares split along a diagonal, with straight sides or small knobs. The piece count is twice the number of squares.

Special — Square. Plain rectangles with no knobs. With no shape clues you have to go by colour and pattern alone, so it is the hardest choice.

Start by finding the four corners and the border pieces and build the outline of the frame. Turning on Edges only leaves just the border pieces, which makes them easy to find. Then group areas of similar colour, such as sky, water or grass, or distinct objects such as buildings and people, and grow clusters before placing them.

The more pieces, the smaller they look on the board, so a large screen is recommended from 150 pieces. If you get stuck, switch on Preview to check the colour and shape of the empty spots.

Under Make from my image, pick a JPG, PNG or WebP photo to build a puzzle with the same settings. The aspect ratio is kept, and images over 2048 pixels on the long side are scaled down. Puzzles from your own image do not support resume or records.

Save printable template on the settings screen downloads the original picture with the cut lines drawn on it (a dark line with a white outline) as an A4 or Letter PNG or PDF. The shapes match what you see on screen, and the title and piece count are printed small at the bottom. On the completion screen you can save the original picture as PNG or PDF.

Images you add are never uploaded and are processed only in this browser. Resume state, best times and the completed list are stored only in your browser (localStorage).
