Standard Sudoku: each row, column, and 3×3 box contains digits 1–9 once

Renban lines: line digits are different and form a consecutive set, not ordered necessarily.

XV: X = sum 10, V = sum 5 between connected cells

Killer cages: cage sums to a given total

German whispers: adjacent digits on the line differ by ≥5.

Palindromes: sequence reads the same forward and backward

Minimum clue: cell is smaller than the orthogonal digits around

Kropki dots: white = consecutive cells , black = 1:2 relation

Shapes: Circle = odd

Solve here

Solution code: column 7

I liked that a lot. Got the first couple of digits early, and then realised that the full break in still had a lot to come. That was really satisfying. I ended up restarting after a bit too organise my notes and colours a bit better and it went nice and smooth.

iEtsh: Glad you enjoyed it
