Sudoku: In the main 9x9 grid, place the digits 1-9 once each in every row, column and 3x3 box.

Modular Lines: Along teal coloured lines no run of three cells may contain numbers with the same remainder when divided by 3.

Full Rank: Each row in the grid can be read as one long number from left to right and another from right to left. Similarly each column can be read as two numbers, top to bottom and bottom to top. These 36 numbers when sorted into ascending order each have a rank from 01-36. Numbers outside the grid indicate the rank of the long number when read from that side.
One digit of some of the ranks have been partly given. The question marks may represent any digit, including zero.
