Multiple-Constraint Sudoku with Renban Groups

(Published on 3. February 2021, 01:38 by zhergan)

Normal sudoku rules apply. Here comes the additional constraints:

Killer Cages: Digits in cages add up to the number in the cage. Digits can not repeat in a cage.

Thermometers: Digits must increase in value from the bulb end.

Arrow Sums: Digits along the arrow sum to the total in the bubble.

Palindromes: Grey lines are palindromes, they read the same from both directions.

Renban Groups: There exist 5 renban groups. These groups must hold consecutive numbers, in any order.
Here is a link to the puzzle on f-puzzles. You can try a harder version Here

Solution code: Row 4, followed by column 9.

This one was lots of fun to solve! All of the rules interacted really nicely to lead me to the next deduction.

The renban groups which were given with letter R are replaced with coloured regions. I've also updated the given f-puzzles links. Thanks SudokuExplorer..

I enjoyed the harmonious interaction of the constraints in the harder version. Thanks for the fun puzzle :-)

I minor critique is that the Rs made it hard to read central pencil marks, so replacing them with coloured regions would be helpful.
Eg: https://f-puzzles.com/?id=y3myhxdc (I've copied the rules too).

@SudokuExplorer: I'm glad you've enjoyed the puzzle. Thanks for solving and warning me about the previous Rs..

Quick little puzzle

@bigger: Thanks for solving..

Firstly I had planned to give some digits inside the cells which are not used by constraints but I forgot it later and added the version with no digits. You may try both via links. Sorry for the inconvenience..
