Dot Rundweg: D1

"Masyu-Rundweg" Puzzle type appeared in Oguz Atay Puzzle Contest(OAPC-8) championship. I was creating this puzzle type but did not followed the rules properly for the black dot. So I renamed the puzzle as "Dot-Rundweg".


Draw a loop into the diagram following the grid-lines, which does not touch or cross itself. A digit in a cell indicates the amount of its edges used by the loop.

The loop should pass through all the circles (both black and white). The circles in the diagram follow the following-rules:
1. The path must turn at every black circle.
2. The path cannot turn at any white circle, but must turn immediately before and/or after.
