Nightloom

The night sky has come undone. Weave it back together.

Each star shows how many threads of light it needs. Threads run straight across or down, never cross, and at most two join the same two stars. When every star has its threads and all of them hang together as one constellation, the sky is woven.

• 24 skies, from six stars to thirty
• A daily sky, new every day
• Every puzzle has exactly one solution, checked by a complete search
• Drag or tap to weave, undo, and up to three hints
• Calm night music, played in your browser; desktop and phones

The rules are those of a classic grid logic puzzle; the skies, art and code are our own.

Code and text written with AI assistance; checked by PN Scripts with automated tests. The sky is drawn and the sound synthesised by code.
