Alright all, when you're playing slots perhaps review the guide to help clear confusion. There are no vertical anything; rows & diagonals. The graphic on the slots also hints for this. Those colored oblongs on the side (blue, green, yellow) with lines beside mark the rows & diagonals. So just connect those matching opposite sides for what's a row/diagonal.
I may look at rewriting the guide a bit as this has come up a lot ^^; A guide fix to help clear this up may help a lot with understanding the slots :3
I'll getcher coins udpated Hunter ^^ Sadly there is no Win on #3 or #4, but #3 was free to play.
