This game is actually somewhat different from traditional Sudoku, but it is more efficient.
In my opinion, it is more like "finding the difference" until all the logic is smooth. If you are really not sure, it will be faster to try.
The general order of clearance is: (I call a 9-square grid a zone, but one horizontal or vertical one is also valid)
1. First look for the individual ones in each community and the ones that are relatively easy to find.
2. Start eliminating gradually. The first situation is that if there are only 2-3 possibilities in the same row or column among the 9 grids, then the entire row and column will no longer exist.
The picture below is a variation, because the first area and the second area only exist in the following two lines (that is, the total line 2.3)
Therefore, all 6 below the third area are excluded.
And because there is currently only one 6 in the second column from the right, we can determine the position of the 6 in the lower right corner.
3. If you cannot tell by just looking at the color, you need to observe the numbers.
Let’s first know a basic concept... If there are only 2 possibilities in 2 grids, then it is impossible to have these two numbers in other grids in the same area.
For example: If there are two grids of 36.36 in the same area, then if there is a grid of 67, then there must be 7 in this grid. This is very simple.
Variation: If there are 3 possibilities in 3 grids, then any of these 3 numbers will not appear in other grids in the same area.
For example: 26.269.29, you can't tell which one is 2.6.9, but if there is another grid at this time that is 12679, then this grid is actually 17.
The same applies to a single row or column, and often needs to be excluded across the entire screen and across areas.
4. Basically learn to eliminate, and you can pass many levels.
If you really can't rule it out, you can only try it, remember the location, and try to find a place where "trying one number can cause more changes", that is, it is best to try one number and you can deduce many places.
If you try a number and come out empty, it means you are wrong.
If you can’t push forward after trying steps 2.3, it is recommended to go back and try somewhere else.

Although it's a bit of a blow to the original poster, it goes against the nature of the game to try it.

How can I explain this. . . The so-called game is "an activity in which everyone follows the same rules." Some people may have set a rule for themselves, "No prompts, just do the questions in the traditional way." This is his rule, and that's no problem. What I think is, "This is a game. I don't look up information and formulas. I just want to use all the methods available in the game to pass the level." This is another set of rules. Otherwise, why don’t I just buy the book and do the questions? Of course, it’s because the UI of this game is beautiful, and you can push it step by step while listening to things. It feels very comfortable to pass the level.

Let me help you explain the second point of the poster. In fact, the logic used in 2 and 3 is the same. Since the 6 in the 1st and 2nd houses are both in the 2nd and 3rd rows, the 6 in the 3rd house cannot be in the 2nd or 3rd row. In the same way, since the 6 in the 3rd and 6th houses are in the 7th and 9th columns, the 6 in the 9th house cannot be in the 7th or 9th column. Combining the positions of 6 in the seventh and eighth houses, it can be inferred that the 6 in the ninth house can only be in the 8th row and 8th column.

Help, I’ve read it twice and I seem to understand it, but I don’t seem to understand it either. Can’t you mark which one is zone one and which one is zone two?

I honestly don’t understand why all the 6’s in the third area are crossed out. Is it because there are three 6’s in a row in the ninth area?
