Pearls of Wisdom was invented by the Japanese puzzle company Nikoli.  The name comes from mathgrant (surprise, surprise).

1. Draw a single loop that connects the centers of the grid cells.

4. The loop may not cross itself or branch off.
5. The loop must pass through every pearl (circle) on the grid.
6. The loop may not turn at a white pearl, but must turn at at least one of the adjacent cells in the loop.
7. The loop must turn at a black pearl, but may not turn at both of the adjacent cells in the loop.
