We need some stats here.
We know for a fact that
RTG operators can alter the characteristics of the slots, but I don't know about Playtech.
I have played this slot recently at FastWin, and it, like many Playtech slots, has relatively low variance compared with many Microgaming slots.
Night Out doesn't seem to give too many bonus rounds, but regular small wins should ensure the balance decreases steadily.
I opened an account at Enter Casino, and did not see anything odd, although when they started offering "too many" bonuses, and started sending me offers for that crop of rogue Playtechs, I discovered the connection. I was also contacted by a "manager" trying to offer me a huge bonus if I deposited £1500, although he sounded "genuine", this is a big Casinomeister NO! (Do not enter into verbal deals with "management", always get it in writing).
It would not be too much of a surprise if this group were "pushing the envelope" as far as they think they can, without actually getting the full rogue treatment.
If Enter Casino return to GoneGambling offering conversions, I will test this allegation by playing this slot simultaneously at FastWin and Enter, and see if anything "odd" is going on. (Hell, I might do it anyway if Enter offer me a decent bonus for a modest deposit & I do well enough elsewhere to "donate" the deposit in the interests of science)
