Hey, @-Dist i am with you on this it is a long-standing thought and although there is no proof generally people think when a new slot is released there is a honeymoon period where it seems to either bonus lots or pays well in the base than all of a sudden its the hardest thing in the world to trigger lol 🙂
Just had a go of this with my VS weekend booster and it seemed a good amount of fun, i got 2 bonuses within about 50 spins, one was a bit crap but then the next one went for £160 ish with an encore spin of x13 giving a line of the blue guy 😀
