Is the population random. I hve seen others in the forum get 100 or 114 but I am stuck at 90. is there a way to change that?

yes, but you have to complete some stuff first.

And if you want to know what you have to do to get a much higher population, PM me. Here's a hint, just highlight the white text.
Hint: It's not the puzzles you have to complete.

Thanks,I found the answer!!
