I'm no good at naming puzzles so if you're wondering where I got Moon River from, check out the ludicrous explanation in the solution guide video description!



Normal Sudoku, Disjoint Groups, Arrow, Little Killer and Palindrome rules apply. Additionally, digits in each cage must sum to N, where N is the same for every cage.

---

Sudoku: place the digits 1-9 into every row, column and 3x3 box.

Disjoint Groups: digits must not repeat in the same position within 3x3 boxes.

Arrows: digits on an arrow must sum to the total in the attached circle. (Where two arrows emanate from one circle, each arrow sums separately to the digit in the circle)

Little Killer: digits along indicated diagonals sum to the total given.

Palindrome: digits along the grey line must read the same forwards and backwards.

Sublime and very hard puzzle! Very clever interactions of the constraints. After understanding those, the puzzle became very smooth. Thank you

Thank you for being such a consistent and talented solver of these ludicrously hard puzzles I keep setting!! Disjoint rules and diagonal-themed clues seem to interact very nicely, as in Di-agony that I made last year, so it was a lot of fun exploring those implications :)

On reflection, definitely nearer 5* difficulty!
