# String Art

Times tables mod n · 30 levels

Pick the numbers that weave the glowing thread picture.

## How to play

- Nails sit round a circle, numbered from 0 at the top. Set the dials with − and +, then tap Weave.
- k: thread every nail to the nail k further on. It makes gcd(n, k) separate loops. m: thread nail i to nail m × i (count past the top to wrap).
- Weave exactly the faint target picture. Gold threads and the loop count are your clues.

k and n − k weave the same star. 9 nails with k = 3 gives 3 separate triangles, because 3 goes into 9 three times.
