Praytech, I myself lost more than 20k USD over the last 2 years, mostly in Playtech casinos; so I think I know how it hurts to lose a lot of money.
I have a lot of experience with various Playtech casinos and now, when I avoid lots of errors that I was doing as a novice and do not let the way I play be influenced by unrealistic expectations, I find the software fair (at least it seems to me that it is fair to me :-)).

I also think you need to take your experience on Playtech software as a whole:
You won 12k at Casino Tropez and lost 8k at King Solomons. So you managed to win 4k overall. Statistically, you are way ahead, in my opinion.
So I think, from a purely mathematical point of view, even if you encountered another loss of a few thousand at KS (not that I would wish you to experience it), it would still not mean that the software is rigged, IMHO.

Also, if you do not use any steep progressions (you wrote your bets are from 1 USD to 5 USD), I think it is quite possible to experience a downswing and to lose 8k (especially with 5 USD bets).

To sum it up, I think your point of view should be that so far, your slots payout percentage has been way above 100 % on Playtech, since you are 4k USD up (if I get the numbers right from what you have posted).

Best of luck in your life!
