Prefer big pieces? Choose 24 or 48 pieces and each piece fills a good part of the screen. Full-screen mode and zoom make them even larger, which is great for tablets, low vision and young puzzlers.
How it works: pick a picture from the library, choose how many pieces you want — 24, 48, 100, 150, 300 or 500 — and start dragging. Every piece is cut by code into a classic interlocking shape with a little random variation, so no two puzzles feel exactly the same. When two pieces fit, they snap together with a soft click and move as one group from then on.
Helpful tools sit above the board: Edges only hides the middle pieces so you can build the frame first, Ghost image shows a faint copy of the picture behind the board, Preview pops up the full picture, and Scatter and Tidy up rearrange loose pieces. Zoom and pan with your mouse wheel, the buttons, or two fingers on a tablet, change the background to light, dark, wood or felt, and go full screen for big puzzles.
There's a timer with a pause button and a progress bar, and your progress saves automatically on your device so a 500-piece puzzle can be finished over several sittings. Turn on piece rotation for an extra challenge — tap a piece to turn it.
