Also could you explain that last part? Does that mean that if the number stops before 1.98 in BPS? Sorry not very good at understanding the house edge for these games sometimes.
The BPS is supposed to average at x1.98 bust. If they have flawed RNG or cheat, they could average the bust at x1.75 for example which increases the house edge as it's harder for the player to win.
To be entirely fair, given enough time, there will be a set of 60 consecutive games in which the SpinBPS is >200 -- simply saying this is unlikely does not mean it should not have happened. Being that the game is not provably fair, it is difficult to say one way or another there were a sequence of games that should have had a SpinBPS of over 200.
In regards to your rationale that there was a "system failure" because the game was not provably fair, I would not agree with you on this. The game not being provably fair is the result of FJ misrepresenting a feature of the game. I would note the game is presently not provably fair.
One could argue (reasonably) the game paying out wins on a 200 BPS, when the SpinBPS was under 200 is a "system failure", and I would agree to the extent it can be believed the seeds were not changed after the fact to make the SpinBPS be under 200.
