Description

AI generated by Codex for Shai. An original touch friendly graph untangling puzzle with five invented constellations, randomized starting arrangements, live crossing highlights, undo, a reset and one star solution reveals. Any valid uncrossed arrangement wins. Crowded stars and stars sitting on unrelated threads must also be moved clear. Original SVG artwork and mathematical puzzle logic are included. These are fictional constellations, not astronomy charts.
