Draw one loop through every pearl, turning at black and passing straight through white.
Controls
Draw a single closed loop that visits every pearl. White pearls are passed straight through, with a turn in at least one adjacent cell. Black pearls are turns, and the cells on both sides along the loop must be straight. Tap near a cell edge to add or remove a line; drag between adjacent cells to connect them.
