Lookie Lookie (Doubler/Look-and-say/Renban)
(Published on 2. September 2022, 03:53 by dumediat)
This is my first puzzle using the doubler constraint, which uses slightly different doubler rules than many other recent puzzles. I hope that you enjoy! Ratings, comments, and feedback are much appreciated! Please feel free to reach out to me on Discord if you have any comments or questions. Please also feel free to try my other puzzles here
Rules:
- Normal sudoku rules apply.
- Renban: Each purple line contains a set of consecutive, non-repeating digit values in any order.
- Look-and-say cages: The clues in the top left corner of each cage are to be read as a Look-and-say number, such that first digit in the clue gives the quantity and the remaining digits give the number itself. For example, a cage with a "24" clue means that there are two 4s in the cage, and a "112" clue means that there is one 12 in the cage. Digits may repeat in cages, if allowed by other rules.
- Doubler: Nine cells (one in each row, column and box) are doublers, and count as double their value for Look-and-say cages and Renban lines. Each digit 1-9 appears in exactly one Doubler, and Doublers may not touch orthogonally or diagonally. Doublers may appear more than once on lines and in cages.

Amazing puzzle! Not too hard once you incorporate all the clues. Very powerful renbans!

Thanks for setting the first look-and-say doubler! This has very clever logic :)

Wow that was brutal, yet so clever. Don't think I've yet seen a doubler constraint that required so little arithmetic to solve. Brilliant puzzle.

Oh boy. Forgot one rule, got stuck, cursed God Almighty and all the angels, realized my mistake, got humble again, solved the puzzle.
