Today I am happy to present very easy GAS puzzle created for Scojo's prompt, this time to create a puzzle with regional constraints and tentropy lines :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Regional constraints: Each constraint type may contain no repeated digits anywhere in the puzzle.
Tentropy: Every set of 4 adjacent digits on the hollow peach line must contain a digit from each of the X-pair (ten-pair) subsets of {1,9}, {2,8}, {3,7}, and {4,6}. A 5 may not appear on a tentropy line.
German whisper: Neighbouring digits along a green line have a difference of at least 5.
Arrow: Digits along an arrow sum to the number in the attached circle.
White kropki dots: Digits in cells joined by a white dot are consecutive. Not all dots are given.
Black kropki dots: Digits in cells joined by a black dot are in a 1:2 ratio (i.e., one digit will be double the other). Not all dots are given.
X: Digits in cells joined by an X sum to 10. Not all Xs are given.
If you liked this puzzle, I recommend trying out my other puzzles: The Erica Series:Lösungscode: First (1st) row of the grid from left to right.

I certainly didn’t find it quick, but very smooth. I liked your use of the regional constraint.

Nice and quick. I'm not very used to Tentropy lines, but the wealth of other clues I'm familiar with made it basically a non-issue.
