I can (for the most part) understand how Same works; however, I have issues in comprehending what exactly causes Plus to appear. Another thing that causes me some headache is trying to understand what Same Wall exactly means.

I feel that I am missing something important, and the tutorial in the actual game itself didn't do much in the ways of enlightening me on these rules.

I can fully understand everything else (Element, etc), but that of the other rules, Plus in particular, causes my brain to simply collapse. I feel that it should be apparent, but try as I might, the answer eludes me.


So my question/plea is this:

Would anyone mind explaining these rules to me, and/or offering certain strategies in using/abusing/defending these rules.



Many thanks in advance.
