Custom & photo puzzles
Everything we know about slide puzzles, organised by what you want to do — play a particular size, solve one, turn a photo into one, or read the maths behind why some boards are impossible.
Step-by-step guide to making your own slide puzzle: pick a photo, crop it square, choose a size, and either play in an app or print and cut a physical version.
Custom sliding puzzles for gifts and personalization: which photos work, which board size to pick, and when to choose digital over physical.
How photo slide puzzles work: how images get squared and sliced, what photos slice well, and the privacy difference between cloud and on-device apps.
How image slide puzzles work: square cropping, on-demand tile rendering with clipping, and why downsizing to 1024×1024 is usually enough.
What a picture slide puzzle is, why it suits children and casual play better than the number version, and what makes a picture work on a 4×4 or 5×5 board.
