Tie threads between brass pegs until each holds exactly its number. Threads never cross, and every peg must join one skein.
Pegs and threads
Brass pegs stand on a dark loom, and each one shows a number: the threads it needs. Tap a peg and its partners light up, the nearest peg in each direction along its row and column. Tap a lit partner to tie a thread between them. Tap it again for a double thread, and once more to loosen the pair.

No crossings
Threads run straight and may never cross one another. A long thread across the loom can cut a whole region off, so every tie is a small decision about what stays reachable. Pegs whose number is met glow green; a peg with too many threads turns red.

One skein
Filling every number is not quite enough: all the pegs must also join into a single connected skein. Big numbers in corners force double threads, ones at the edge allow only a single strand, and the crossing rule settles the rest. Each loom has one true tying.

Five looms
Five looms grow from a five-peg warm-up to a thirteen-peg weave. Undo takes back your last tie; Restart clears the loom. When the skein holds, the threads turn green: tap Next. On the last loom, Again returns to the first.

Controls
Tap a peg, then a peg in line with it, to tie one thread, two, or none again. Tap Undo, Restart or Next as needed. On desktop, click instead of tapping.
