By playing a lot of Play n Go slots I believe that Play n Go uses a so called strategy that if you play long enough with the lowest possible bet you can win some additional amount of cash but as soon as you double your bet or make it 4x,8x and 16x higher than the lowest one it is exactly there where this provider busts you.Just my experience with this provider that I play since 2019 so I have truly a lot of experience with them and it seems in games with mechanics like Sword and Holy Grail and Green Night it looks like the lowest bet is your friend.
Anyways, it is all about luck and how slot RTP works on the same day. Otherwise, we all get rich on same day with doing same things over and over. But we all know this is impossible in the long run.
