Ring-ring 💍💍

     Living up to its name, Ring-Ring is a silly loop genre (a peculiar one, as it features multiple loops) with very simple-looking grids and ruleset. Speaking of which, Here are the rules :

Draw lines through the center of cells to fill all empty cells with a rectangular loop.

- Loops may cross each other, but may not overlap or share a corner.

- Loops cannot go through shaded cells.
