It is a life changer winning for most of us but it might be just a normal winning for the player.
Betting $50 per spins in slot games means that the player is someone who have decent amount of starting bankroll.
We do not know how many thousands spins he needs before he hit that max multiplier in Starlight Princess.
What we can hope is that this winning is still profitable for him, as it is also impossible that the winning is still less than what he has lost before.
