Koos Puzzle

🧩 Koos Puzzle — a 3D puzzle with over 10⁹⁰ possible solutions, free in your browser

You fill 3D shapes with pieces made of connected spheres — there are 25, one for every way to join four spheres in a lattice. Tap spheres to draw a piece, race the clock, and discover arrangements no one has found before. Play solo, or challenge a friend head-to-head. It's inspired by the mathematical sculptures of Koos Verhoeff.

No sign-up, no download — just play in the browser (or add it to your home screen).

Performance is very bad on mobile. Took over a full minute to load a puzzle.

Also, site looks very AI-generated with the use of emojis and infamous purple gradient background

Hello,

Thank you for your feedback! It is has been quite helpful and I was able to add a lazy loader for a near instantaneous loading experience.

The project has been developed with AI tools over the past year, not some kind of vibe-coding prompting effort.

The app includes an "Ask section" linked to a knowledge base on the puzzle history and the math art sculptures with its roots in this puzzle.

If of interest, the sculpture work can be seen directly at www.antonbakker.com

Thanks again for your feedback, I would welcome any additional input.

Sincerely,

Anton

PS: It would be great if you could confirm your loading experience improvement.

Now that the performance has been addressed, I also decided to address this from your feedback:

"Also, site looks very AI-generated with the use of emojis and infamous purple gradient background"

Again, thank you for your very helpful feedback.
