Normal Sudoku rules apply. Gray lines are Renban lines; they must contain a set of consecutive, non-repeating digits. The inequality sign points to the smaller of the two adjacent digits.

First time setting with Renban as a constraint, so any feedback is highly appreciated!
Solution code: Column 1 followed by column 2, no spaces

Enjoyed this. Took me a few run ups, I kept making a mess with my notation.

lovely puzzle! Definitely tough to solve but very rewarding once you find the candidates on the inequality :)

Very elegant puzzle, loved colouring it all the way down to the inequality sign. It was very hard though and took me quite some time :D
