SG is like obscenity, know it when you see it. Not too important. Just sometimes wonder about marginals, say, 3 or 4 in 1st 3 columns.

RS is new to me. Tried playing it like GE but think I'll record results for variations of 4 out of 5, and see what I get. Could watch youtube and write things down, I suppose.

CF is new to me. Any time you have a shot to finish 1 remaining in any column? Or is that more youtube watching to try to figure it out.

Lots of guess and by golly going on when I walk into a joint.

Incidentally it is so cool on PGF to know the RTP! So many thanks to MC, it is hilarious - I want to tell people "Hey, this is 93% and down the street it's 89%." It's like forbidden knowledge on a slot but now I know.
