I have tested the slot myself, and i want to mention some things about slot potential and such.
If you buying 1000x bonuses, you're mostly guaranteed to get like 100-600x back, I always got the best symbols stacked in a row at end when its under 100x win at last 2 spins. You usually can get any picture symbol stacked in first reel with 2, then 2nd and 3rd on end spins
It took me about hundred demo bonus buys until i got an decent setup, once i got 4 same 2nd best symbol with 200X on it (200X^4 is 1600000000 ways, probably max win by that point)
How often profit, was about 1/10 times, slot has nice potential though. I might try it in a week later and see if i get in.
Most spins i got is 12 or 13. Usually 11
