Today I’ll solve the Black Square Puzzle by the Russian designer Vladimir Krasnoukhov. This tray-packing puzzle consists of only 5 pieces – 4 half trapezes, and one square. It seems like a lot of space is available – but the square just doesn’t fit in…
I hope you enjoyed the solution! I personally found it beautiful. I don’t think there’s a single thing I’d improve with this design.
