About Loop Puzzle

Loop Puzzle is a free Slitherlink site for people who want to play without ads, pop-ups or accounts. It runs in any modern browser on a computer, tablet or phone, and keeps working offline once you have opened it.

Every puzzle is made by our own generator and checked by a solver before you see it, so it has exactly one answer and can be solved by logic alone. You can play as many as you like at every level, from Easy to Expert, plus one daily challenge.

Loop Puzzle is made by ChaCha Studio. You can find all our puzzle games at chacha.im.
