Pearlloop Pearl Trail

Trace the single trail that satisfies every pearl.

Pearlloop Pearl Trail is a classic Masyu-style pearl-loop puzzle: draw one continuous, closed line through a grid of dots so that it obeys every pearl clue sitting on the lattice. No numbers to add up — just the shape of the line itself.

HOW TO PLAY
• Tap the gap between two dots to draw a line there. Tap again to mark it blocked, and once more to clear it.
• A WHITE pearl means the trail must run straight through that dot — but it has to turn at one of the two dots right before or after it.
• A BLACK pearl means the trail must turn at that dot — and then run straight through both of the dots right before and after it.
• The puzzle is solved the instant every pearl's rule is satisfied and the line forms one single closed loop with no branches, no dead ends, and no crossings.

WHAT'S INSIDE
• New — three grid sizes, from a quick 5×5 warm-up to a real 10×10 sit-down, every puzzle procedurally generated fresh on your device.
• Play — a clean, tappable board with live warnings: a broken pearl or a branching dot turns red until you fix it, so you always know exactly where to look.
• Daily — one pearl trail a day, the same puzzle for everyone, with a streak counter that rewards coming back.
• Learn — a plain-language walkthrough of the white-pearl and black-pearl rules, plus a tiny hands-on practice puzzle so the logic clicks before you tackle a full grid.
• Awards — eight milestones to unlock as you solve more trails, explore every grid size, and keep your daily streak alive.

WHY PEARLLOOP
• Completely offline. No internet permission, no accounts, no data collection of any kind.
• No ads, no interstitials, no purchases. Just the puzzle.
• No sound — feedback is a light haptic tap and a clear visual cue, so it's as calm in a quiet room as anywhere else.
• Every puzzle is generated on your device from a fresh random seed (or, for the Daily trail, a seed tied to the date), so there's always something new to trace.
• Best-time tracking per grid size and a running solve count, stored privately on your device.

Pearlloop Pearl Trail is built for a few quiet minutes at a time: pick a size, trace the trail, watch the warnings disappear one by one until the loop closes clean.
