Type bad C Sudoku
(Published on 16. November 2020, 07:48 by bigger)
Standard sudoku rules applies. Fill the grid with numbers from 1 to 9 so each digit occurs exactly once in every row, column and 3x3 box.
Four digits surrounded the circle mean one digit has a different parity than the other three.The one different-parity digit and the digit that is beside the circle but not beside the one are both shown inside the circle. In other words, two digit in cirle,one of them is the different parity digit, the other one is not sharing an edge.
All possible circle are given.
This puzzle is made by Old Miles from China in 2017. It belongs to a challenge where Old Miles tried to make one different variant every day in 2017. Some of them are too easy. Some of them are too hard(seriously, nobody ever manage to solve those). I'm only going to choose those that actually have interesting rules. I hope you would like this series.
Solution code: row 2 and column 2(18digits)

Very easy vision.

Confirmed with the author: in the 2*2 squares marked with circles and numbers, the marked numbers appear in the diagonal direction, and at the same time, 1 number in them has different parity attributes from the other 3 squares. All eligible 2*2 squares have been marked in the middle. Note: negative constraints!

Can you rephrase 'the digit that is beside the circle but not beside the one'?
Which one of the three having the same parity is it?
It is the one not sharing an edge, isn't it?
