About the game
Pearl Loop is a logic puzzle also known as Masyu. Draw one closed golden string through the centres of the cells so that it passes every pearl. On a black pearl the string must turn, then travel straight through the next cell on both sides. On a white pearl it must go straight through, and turn in at least one of the cells just before or after.
Each pearl judges you live: it glows green as soon as its rule is met and pulses red the moment it is broken. Thirty-six boards grow from five by five to ten by ten, each with exactly one loop that you can find by logic. Drag to draw, drag again to erase, and tap between two cells to mark a spot the string will never use.
