Hello, everyone. A little construction for your consideration and enjoyment!

CTC:

This is a fairly difficult one

Please evaluate the puzzle and leave feedback. This helps me construct better puzzles.

Standard Sudoku rules apply. Fill the grid so each row, column, and 3×3 box contains the digits 1–9 exactly once.

German Whispers. On green lines, adjacent digits differ by at least 5.

Renban. On purple lines, digits form a set of consecutive, non-repeating numbers in any order.

Kropki. A white dot joins consecutive digits; a black dot joins digits in a 1:2 ratio. Not all valid dots are necessarily given.

Solution code: Row 9 from left to right. 9 symbols in total

Very nice puzzle with interesting renban interactions. Instead of coloring I used placeholder digits, which worked out quite well

This would be a great puzzle to introduce people to cryptic sudoku: just clever enough to feel like you're having fun, but easy enough that you can work through it with a new solver without losing them.

A tricky challenge! Didn't expect to be able to color but it worked out. I loved the fountain <3
