Meanest Mini
(Published on 1. January 2024, 17:10 by chameleon)
Mean mini sudoku: place six distinct NUMBERS from 1-9 in each row, column and box without repeats.
Lines with circled cells and mathematical operators between them must contain a true mathematical equation.
Oh, yeah, you probably already guessed it, but the numbers don't have to be integer. They must be real, though.

Solution code: the value of the top-left cell (row 1, column 1), with the first 4 digits after the decimal point and no rounding up (e.g. "3.1415")

Wow. This puzzle is something else. Perhaps the coolest part is that despite the obvious wackiness, it manages to keep the essential flavor of a mean mini.

Stunning puzzle. I set myself the extra challenge of not using a calculator, it only took two sides of A4.

Very nice concept and setting.

Interesting concept. Not extremely hard, but it is weird needing to work with approximations rather than actual numbers and not really knowing what order some of them are in. I do disagree with the earlier comment that most of this puzzle is about math deductions. I actually found that attempting to do math before the grid was complete was pretty useless, it's really all about min-max evaluations that you'd also need in some of the more complex killer sudokus.
Of course you will need a fair knowledge of math to find the actual numbers, which BTW even with four decimal positions are still approximations.

The sudoku part is very fun! The maths part is insane! I would be admired if someone could solve this puzzle without any note and calculator!

Yeah, this puzzle is unusual in that like 90% of the deduction aren't really sudoku, it's just doing a bunch of maths. Luckily I really like maths, so I enjoyed this puzzle a lot; it's a really cool and funny concept, and very well executed.
