According to my past experience on Dice game platforms, they all claims their games are Provably Fair.
But in reality, suddenly a losing streak over 20 losses in a row will happen when your account performance is good, which over 25% earning.
Anyway, this is just my past experience. Maybe MagicDice is really Provably Fair up to today.
I share one of my posts related to MagicDice here for the reference.
