Warning, this is a 5 star difficulty. You probably should try my previous ones, or you might break this one too many times.

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.

The box number in its box would turn all different parity cells that are in its box and in its 8 surrounding cells into the box number.

Normal kropki rules applies. 12 can be black or white. The dots treat the turned as the turned.

All possible dots are given.

All the digits in orange square turned into 2, other digit won't be turned.

This puzzle is made by Old Miles from China. The title is something we say when we break stuff during Spring Festival. I break it like about 2 times. Don't put too much faith in yourself if you haven't solve my previous ones. This one has an interesting box 4.

My thought on this series. The rule has changed a lot compared to other ones. This is probably the most complex rule. Every turned digit need to fullfill three conditions-in a certain box, beside a certain digit and have a certain parity. There is just no way to use the rule you want to rather than the one I intend you to. Yes, I never get over with my first puzzle. As my rule of thumb goes, the more complex the rule is, the easier the puzzle gets. However, this series show the next line, the easier to break the puzzle. Also the puzzle is very rewarding, every tricks you found in the rule will results in a break in.

It also has a lot to do with the box while other puzzle focus more on row or column. 6X6 and 9X9 have more difference other than limiting digits and combinations. 6X6 has connected same parity boxes while 9X9 has isolated parity boxes. That's why this is probably my favourite series by far.
