Double Date [Doublers, Killer, Renban, Arrow collab with Tallcat]

(Published on 15. April 2024, 14:47 by Malrog)

Tallcat and I are proud to present this puzzle to celebrate our joint birthday. I approached Tallcat almost a year ago to suggest a collaboration on this theme, and we're both very pleased with the final result. Many thanks to him for agreeing to this project. The setting process for the first parts of this puzzle was streamed live, and the video can be seen on YouTube, although obviously this will spoil the opening of the puzzle, so don't watch until after you've tried it!

Rules:

Normal sudoku rules apply: place the digits 1-9 in each row, column and 3x3 region.
Normal April 25th rules apply: two 2s, four 4s and five 5s are considered to have double their value, for the purposes of the following clues.
Normal killer rules apply: digits must not repeat in cages, and the total sum of all values in the cage is given by the small number.
Normal renban rules apply: digits along a purple line must form a set of consecutive non-repeating values.
Normal arrow rules apply: values along an arrow sum to the value in the attached circle. Digits can repeat on arrows if allowed by other rules.

That was a wild and engaging ride! Allowing certain instances of digits to be doubled really added an extra layer of thought for the calculations, which one really has to be precise when solving.
I guess I can say: Trippy maths allows for some trippy deductions which then result in trippy surprises x)

Great puzzle - a privilege to test it - clean and innovative (April 25th rule) logic: and also some things which made this solver smile when they were uncovered.
