---- RULES ----

Normal Sudoku rules apply: Fill the grid with digits 1 to 9 appearing once each in every row, column, and 3x3 box.

Wrogn Loop: Draw a single 1-cell-wide loop of orthogonally connected cells into the grid. The loop cannot touch itself orthogonally but may touch diagonally. All clues along the loop are wrogn. A clue is wrogn if it is not 100% fulfilled. The loop must furthermore pass through all cells belonging to a wrogn clue.

Box 1 - Little killer clues: Clues outside the grid give the sum of all digits along the indicated diagonal.

Box 2 - Thermometers: Digits increase along a thermometer starting from the bulb end.

Box 3 - Killer Cages: Digits in a dotted cage sum to the small number given.

Box 4 - Min/Max Cells: Cells with arrows pointing inwards (outwards) must contain digits smaller (greater) than all orthogonal cells. (Note: the loop must only pass through the Min/Max cell, not through all adjacent cells, to mark it as wrogn)

Box 5 - V-clues: Cells connected by a V-clue add up to 5.

Box 6 - Nabner Lines: Digits along golden lines cannot be consecutive, regardless of their order along the line.

Box 7 - Dutch Whispers: Adjacent digits along red lines must differ by at least 4.

Box 8 - Even/Odd: Digits in gray squares are even, while digits in gray circles must be odd.

Box 9 - Kropki Dots: Cells connected by a white dot contain consecutive digits. Digits in cells connected by a black dot are in a 1:2 ratio.

Very lovely puzzle! Once I funny understood the line rules with respect to the other clues, suddenly everything started to click.

Very easy and smooth to start but the end is harder

Nice idea!
It was quite hard for me to finish the puzzle after I found the line and what's left is an almost plain sudoku

Really impressive! I'm surprised that literally EVERY clue has it own job to do! Awesome!

That was great! ElChiglia is now added to my mental list of setters whose puzzles I will look out for.

Fun puzzle! A lot of cool wrogn deductions in this one, and definitely not as difficult as it may first look.

@Big Tiger: it's not easy to reply to your comment without including spoilers, but did you manage to obtain already some information about the loop?

on 23. December 2023, 11:12 by Big Tiger
Well, I'm stumped. Can't even get the first digit. Definitely harder than 2 stars for me.
