I have playing both of these games.
is it fair or no fair ? this is hard to say.
Because of luck is Hard to say,
We are possible to lose 50 times in a row,
also possible to win 10 times in a row.
But I think lose probability > win probability , greater than 2 !
I can only say,
Just only play a few times,
Don't be addicted,
Otherwise, we must be the loser.
