• Normal Sudoku rules apply.
• Digits along a red parity line must alternate between odd and even.
• Adjacent digits along a green German whisper line must have a difference of at least 5.
• Digits along a magenta renban form a set of consecutive non-repeating digits in any order.
• Digits along a blue line create a sumline where the sum of digits on a line within a particular 3x3 box must be the same for all the boxes the line passes through.
• Digits along an orange Dutch line must have a difference of at least 4.
• A white dot between cells indicates cells with consecutive values.
• Not all dots are shown.
• A V between two cells means they add up to 5.
• An X between two cells means they add up to 10.
• The board is covered in fog. Place a digit correctly and the fog will lift around it.
A puzzle for my husband, who is Australian, for Australia Day.

I really enjoyed the break in! I can't solve many 2/5 stars so I'd definitely give it a 1/5.

Fair dinkum puzzle sport - start was a bit tricky but afterwards was quite easy.

Very nice approachable puzzle (I got stuck in the middle due to my own ignorance). Beautiful interactions between clue types.

I found the break in really challenging, but I think I was missing something obvious. Once I got the break in everything elder was very quick.

I rated this 2/5 difficulty
This was a great approachable FoW puzzle! There were a lot of nice ideas, and the solve 'flowed' very well.
I think this puzzle is overall a low 2/5 difficulty, as it did take me a while to spot a one of the 'key steps' in the early midgame (and this step seemed a bit too difficult for a 'true 1/5 difficulty puzzle').
That said, none of the steps were 'complex' (difficult) conceptually/logically, though a few were tricky to spot. A beginner solver should be able to solve this puzzle independently if they are familiar with the 'basics' of each rule[set]. In any case, I definitely recommend solving the puzzle for an enjoyable & approachable solve!
