Logic Masters Deutschland e.V.

This time Calvinball and I got inspired by EdTheAlchemist's Squishscraper Square to make this puzzle.

• Place the digits 1 through 9 once each in every 3x3 box, without repeats in any row or column. Cells on region borders (dashed lines) are shared between multiple boxes.
• Spaces outside the grid indicate the number of grid digits seen in that direction, for that effect, digits block any lower or equal digit from being seen.
• A digit on a circle indicates how many times that digit appears on circles.
