Yes the start is key... like you saw I had wilds everywhere in the end. I started with like 5 wilds in the screen + had a wildcard with additional 6 or 7 Wilds (4 of them in a row + one really close)
The potential is coming from the wilds hitting wild frames again. Like you see in the corner I had everything only just 2x. My win could have been much better with just one wild hitting a wild frame for x3.
