Puzzle Shark is a jigsaw design software. You can use it to generate and tweak jigsaw puzzles with irregular piece shapes. You can use it to design individual jigsaw puzzles for your friends and family, assuming you have a tool to cut them out.
The most common material we use is plywood sheets. We use a laser cutter to cut out the pieces. But if you have some other tools that can work based on SVG files, you can use them too.
We have already cut out puzzles which were designed with Puzzle Shark. Still, the software is in an early stage and things will be undocumented and sometimes fiddly to use.
Puzzle Shark is written with the Godot Engine 4 in GDScript. This means that if you currently want to use it, you'll need to install Godot 4 and run it from source.
