String of Pearls

String of Pearls: The Ultimate Logic Puzzle

Unwind and sharpen your mind with String of Pearls, a beautiful and minimalist logic puzzle experience.

Inspired by the classic Japanese "Masyu" puzzle (first published by Nikoli), String of Pearls challenges you to create a single, continuous loop through a grid of black and white circles. It’s a game of pure logic—no math, no guessing, just satisfying deductions and the elegant "click" of a solved puzzle.

HOW TO PLAY
The rules are simple to learn but offer endless depth:
1. The Loop: Draw one single, continuous loop that connects all segments. No branching paths or loose ends allowed!
2. White Pearls: The loop must pass straight through white pearls. However, it must turn 90° in at least one of the adjacent cells (before or after).
3. Black Pearls: The loop must turn 90° inside a black pearl. It must also travel straight for at least one full cell in both directions immediately after the turn.
