There is such a small difference between the hearthstopper bonus and the normal ones, its not really worth chasing the heartstopper feature.
I just give the game 50x stake, and leave when its eaten that much.
Takes a couple weeks to fill the 40 hearts, but it does not really matter since the normal bonuses are just as good/bad.
Yeah the enhanced feature never plays enhanced.
I’ve had about 10 of these bonuses now and only one has paid out well, around 150x
The others all paid between 10x and 50x, the last 3 have had no extra heart wild appear on the reels.
Never seen a re-trigger on any bonus either.
