Galette, which means wafer in French, is an aptly named puzzle for this thin packing puzzle. It has a simple goal - pack all 5 tetromino pieces inside the box. But a simple goal doesn't mean an easy solution.
A tetromino piece is made of 4 voxels, or 4 cubes attached together.
There are 2 openings - a wide one from the top and a small one from the side.
However, this small opening changes everything. Not only is it blocking the way pieces fit inside, but also restricts their path inside the box, while hiding them from your vision.
This simple addition turns Galette into a considerable challenge. Do you think you can solve it?
