Normal sudoku rules apply.
Orange “entropic” lines contain a low digit {123}, a medium digit {456}, and a high digit {789}.
Adjacent digits along green “whisper” lines differ by 5 or more.
Box borders divide blue “region sum” lines into segments with the same sum.
Pink “renban” lines contain a non-repeating consecutive sequence in any order.
Black dots separate digits where one is double the other.

Nice consistent level of difficulty throughout. A lot of easy puzzles, once you get started, the rest just falls into place in a matter of minutes. This was interesting right to the end. Thanks!

I thought this was going to be frustratingly difficult. But I saw Blobz' name, and have enjoyed his puzzles in the past, so I decided to give it a try. One step leads to another in a surprisingly doable sequence...which to me is a sign of high quality setting.

Novice Sudoku player here. Thanks to CtC's Simon's teachings, this puzzle was a breeze. Nice and easy logic. Didn't get stuck too much and fun to solve. Still took me a bit to see the next steps off and on.
Great beginners puzzle for connecting various logic types together. Definitely manageable.
Thanks Blobz!

Fun snack, but the hardest part for me was differentiating the colors (color blind here). Fun solve
