Rules:

• 10x10 Ring-Ring/Masyu: Draw rectangular loops through the centers of some cells so that every white cell gets used. Loops may not travel through black cells. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap. When a loop goes through a black circle, it must turn and travel straight through the cells on either side. When a loop goes through a white circle, it must go straight through and turn in at least one of the cells on either side. Each circle contains loop segments from exactly one rectangle.
• The gray nodes represent either black squares, white circles, or black circles. The solver must determine what each gray node represents (solution check requires correct loops and shading).
