I played a lot of Reactoonz and Wild Falls the last week. Ripped over £1000 at £0.20 bets playing over 3 sites at the same time whilst taking part in an equalised win tournament. Not sure how many spins I did, estimating around 50 000. I couldn't track it with slot tracker, for more then the first couple of hours, as playing through Chrome caused the games to lag to and stall. PC issue.
I came up with all kinds of conspiracy theories based on my experience and the observations of the scores other players were posting.
Garga showed up roughly once every 1000 spins.
Got 15 pinks twice in total, 5 spins apart, just the 750x versions.
Wild falls gave me a 700x win and not much else.
