Daily Loop: Slitherlink

Trace one unbroken loop. Daily Loop is a Slitherlink puzzle with a twist of light. Every day a single new grid arrives, the same one for everyone, and your job is to draw one closed loop through it. Tap between two dots to light a segment; each number tells you exactly how many of its four sides the loop must use — a zero stays dark. Light the right segments, join them into one continuous circuit, and the whole loop ignites. There's never any guessing, and there's always exactly one solution. PICK YOUR COLOR Loop is yours to tint. Choose from five neon themes — Phosphor, Ion, Filament, Plasma, Ember — and your trace, your solve, and your shared result card all glow in the color you picked. Change it anytime. A DAILY YOU CAN KEEP One puzzle a day, a gentle climb from Monday to Sunday. Solve to build a streak; a banked freeze quietly covers the day you miss. Beat the par time for more stars, then share a spoiler-free result that shows your color, your time, and your streak — never a single segment of the answer. PLAY THE WORLD, OR DON'T Sign in to Game Center to compare today's solve time and chase the longest-streak board, or skip it entirely — there's no account and no login wall. Optional iCloud sync carries your progress between your own devices. HONEST AND FREE The daily puzzle is free, every day, with no ads on the board. Loop+ is an optional one-time unlock (not a subscription) that opens unlimited practice puzzles across four difficulties. The daily always stays free. No accounts, no tracking, no noise. Just one glowing loop, waiting for you each morning.
