Rules:
Normal sudoku rules apply.
Along each line, the hexagon is referred to as 'position 1', the next cell along is 'position 2' and so on. Digits never repeat along a line.
PURPLE LINES are thermos. Digits along thermos always increase as you move away from the hexagon. Eg: 24579 would be a valid thermo.
TURQUOISE LINES are index lines. On an index line, the digit in the Nth position indicates the position along the line where the digit N appears. Eg: 32154 would be a valid index line. The 3 in the 1st position indicates there is a 1 in the 3rd position, and so on.
LIGHT BROWN LINES are hitlines. Digits can be in any order on a hitline, but the digit in the hexagon indicates how many digits along the hitline match their position number. Eg: A hitline might read 27315. The 2 on the hexagon indicates that exactly two digits match their position number; in this case, 3 in the 3rd position and 5 in the 5th position.
SHENANIGANS: One of the digits 1-9 (to be determined) is the 'mischief digit.' Every line follows one (AND ONLY ONE) of the three line rules above, but any line containing the mischief digit has been painted the wrong colour. (Any line NOT containing the mischief digit is the correct colour.)
Solution code: Column 9 reading downwards

I got to the final two lines without using (nor realising) the ONLY ONE TYPE rule.
Got stuck there for an hour, then reread the rules. So I have no idea how hard it actually was. Ha. Thanks again marty <3

Fantastic puzzle. Seemed impossible at so many steps until it wasn't.

Fantastic puzzle! it took me quite a while to figure it out but it was very satisfying to solve.

Excellent puzzle, not so difficult. I'd say 3* is more accurate.

Oof, that was hard. 6 stars out of 5 for me.
The break-in eluded me for over a day. I had finally given up and started the CtC video looking for a hint, but luckily, I got the final bit of inspiration I needed while Simon was reading the rules. After that, it was relatively smooth ... until the endgame. That took me forever as well.
Happy belated birthday to VikingPrime!

Definitely harder than mischief, but really fun! Took me so so long to work out a break in, but very satisfying when it clicked!

Only you could make a liar puzzle feel so utterly fair. Thank you for this. Quality setting as always but it pales in comparison to the quality of your friendship.

Whow, this was some great logic!!
(Also, I solved it mere second ahead of tuturitu. Sorry tuturitu!)
