It takes only a reputable casino to keep an RTP around 86% and it actually worked that way. In the end, we are looking for a win not RTP, which is why I do not care bout it.
An RTP around 86%? That seems too low. I'm not sure if there's anybody who prefers to play with that low RTP when its competitors are mostly offering above 95%.
What do you mean you don't care about RTP but you're looking for a win? If you're after a win, then you should be chasing slots with higher RTP. The higher the RTP is, the higher the amount that you could win back. So, it matters, especially if the difference is big.
If you aren't after wins, then you may not care about RTP. You won't care if in a $1,000 bankroll only $800 is designed to be returned to you, even if there are other slots which offer $980.
