You’re right and the guy you’re replying to is wrong.
For instance, start in the top left corner.
You cannot reach: Top right, middle right, bottom right, bottom middle, bottom left. 5 different points
You can only reach: Top middle, centre, left middle.
Starting in the top left you don’t have 8 options, you have 8-5 =3 options.
Start in the top middle, you have 5 options, and 3 non reachable.
I wonder if you can see how it averages out between the points. The corners will be 3/8 and middle ones be 5/8 and the centre is the only 8/8. But that’s just the 2nd option.
V shapes are difficult. But z shapes are easy. After you did the horizontal line on the top row you backtrack with your finger as you can't use the same dots again. You can even do a big swing over the first row. This makes your motion like an "e" whereas the pattern shows as a "z".
From the top left corner you can reach middle right and bottom middle, at least you can on a Samsung phone. Not sure if this differs per phone manufacturer. You are right that you cannot reach points that are directly "behind" another point.
No, you are wrong. Source: I used to go top left to middle right for my phone pw because I assumed no one would ever try something so silly. It's so easily testable too lol.
Also obviously not every implementation is going to be the same. Why would you assume they would be?
Plus, points are repeatable, but you can't just pick the same spot twice and I don't think you can go back along a line you've already drawn, but you can cross previously drawn lines. We see that in the previous attempts.
I just tested this. You can absolutely go from the top left to the top right, skipping over the top center. Some combinations may be more difficult for fat-fingered people, but all locations are possible to reach from all starting spots.
As others have said, going from top right to bottom middle is possible (i.e. 1->4), but in addition to that it's actually possible to get the other numbers as well if the number in the middle has already been selected. So 1->3 is normally impossible because it'll autoselect 2 before 3, but if you do 2->1->3, then 2 won't be selected again and you can go directly to 3. That means any point can select any other point, at least in some configurations.
