Well, thanks to Len, I managed to unlock my phone again, but now everyone knows my pattern, so I need to choose a new one.
For brevity, I won't include the explanation of how an Android pattern lock screen works again, but you still need to follow those rules (see previous puzzle).
Here's the rules for my new pattern:
- I still want to use all nine dots
- I'm still obsessed with mirroring, so it must still have reflective symmetry
- I don't like odd numbers, so the pattern's resulting line must have exactly two "ends"*
What should my new pattern be?
* by this I mean that visually, the final line formed by the pattern has exactly two dots which have a single line connecting to them. So, for example the pattern
2 1 3 has two line endings (at 1 & 3), but
5 2 1 3 has three (at 1, 3 & 5). All solutions found for the previous puzzle have three line endings.
