So here's a little new thing I created of which I thought it might be fun!

- Ring-Ring: Fill the grid by drawing rectangles that consist of horizontal and vertical lines between cell centers. The sides of different rectangles may intersect but cannot overlap. Rectangles can’t touch otherwise; in particular, they can’t touch by a corner.

- Worm : Travelling through the grid is a worm, moving orthogonally from cell to cell. It may touch itself, it's not a thick snake, it's a slim worm. Its head and tail are found at the circles. The worm can cross a rectangle only on cells with a straight segment and cannot take a turn on those segments (see the visual example for clarification).

- Outside clues : Red clues to the left and and the top indicate the number of cells that contain worm segments in the respective column/row. Black clues to the right and at the bottom indicate the number of cells that contain Ring-Ring segments in the respective column/row.

Note: All cells in the grid have to be covered by either Worm or Ring Ring segments, or both.
