Earlier this year I solved aqjhs's puzzle "Cuitláhuac", which used a combination of full rank and modular lines/dots. This inspired me to experiment with other common line variants, which culminated in the creation of the puzzle below. I hope you enjoy :)

Sudoku: Place the digits 1-9, once each, into every row, column, and 3x3 box of the central 9x9 grid.

Full Rank: The digits on columns and rows, read in both directions, make a total of 36 nine-digit numbers. Numbers in dominos outside the grid (read left to right or top to bottom) show the rank in ascending order among those 36 numbers for the indicated column or row in the direction of the clue, where the lowest number has rank 01 and the highest number has rank 36. There are no ties in rank. Clues can contain any digits from 0 to 9.

Region Sum Lines (RS): Box borders divide each blue line into segments with the same sum. Different lines may have different sums.

German Whisper (GW): Along green lines, adjacent digits differ by at least 5.

Renban Lines (RB): Along pink lines, digits form a consecutive sequence in any order, without repetition.

Palindrome (P): Digits read the same way from either end of a grey line.

The digit in the grey square is even. The digit in the grey circle is odd.
