In recent days someone made $1mln with a $20k Madame Destiny bonus buy while I can't even hit 5x after 19 bonus buys on the same slot. Watched the replay of win and there were more than 8 retriggers with over 65x multi

When I know there is a huge win on a specific game especially pragmatic play, I will prefer to avoid playing the game. Of course it is just my own feeling that once there is a huge win, the game will be likely in freeze mode with lower chance to win. My best in Madame Destiny Megaways with buy feature was around 30x, it was long time ago but with $100 buy only and it was not happened in Stake.
Sometimes I watch what the streamers are playing and join in on those particular games. I've had fairly decent luck! Even though its just for a bit of fun.
