Yes. Loomlock is completely free, needs no account or login, runs entirely in your browser, and is supported only by ads. There is a new board every day plus a playable archive of past days.

What kind of puzzle is Loomlock?

A daily loop-deduction puzzle in the Nikoli slitherlink family. From numeric cell clues you deduce, edge by edge, the single closed loop the board allows. Every board is verified at build time to be uniquely solvable AND solvable start-to-finish by pure logic with no guessing.

What does no-guess mean in Loomlock?

The no-guess integrity check blocks any edge you cannot yet prove from the clues, so you can never lock in an unprovable or wrong line. A Loomlock solve is earned deduction, never a lucky guess — that guarantee is enforced, not just marketing.

Can I share my Loomlock result without spoiling the puzzle?

Yes. The share card is a spoiler-free solve grid — Loomlock #N, your time, hints, and streak — that reveals nothing about the loop, so it is safe to post beside "beat my time." The finished woven loop is a private keepsake, never the shared image.

Can I play past Loomlock puzzles?

Yes. Each past day has its own permalink at /p/ so you can play any earlier board and chase your best time or a no-hint solve.

Loomlock

A free daily no-guess loop-deduction puzzle.

Loomlock is a free daily logic puzzle in the Nikoli slitherlink family. Every day brings one fresh grid of numbered cells, and everyone in the world solves the same board — so any two times are directly comparable. Each number tells you exactly how many of its four sides the single closed loop runs along; tap an edge to cycle it through line, blocked, or blank, and build one continuous woven loop edge by edge. The no-guess integrity check refuses any edge you cannot yet prove from the clues, so a finished solve is always earned by logic and never by luck. Close the loop, lock a spoiler-free solve card of your time, hints, and streak, and come back tomorrow to keep the streak alive. No account, no download — it plays in any browser and is free.
