Tetracide (percentages, algorithm)

This puzzle should be explored after Square Sardine Packing. Choose some shapes – order them from first at the top (green rectangle) to the last at the bottom (purple rectangle). Now use the same algorithm that you used in Square Sardine Packing to pack the...

Square Sardine Packing (percentages, algorithm)

The big square is squeeze-packed according to a strict set of rules called an algorithm. Let’s call this algorithm Square Sardine Packing. Can you figure out how it works in this big 9×9 square? Here is Square Sardine Packing on a 12×12 square. Try to...
