You actually don't need a mentor in dice gambling because that is the easiest game that you can play in the casino, there is no also a limit loss as this is only a luck-based game so you cannot do anything to stop you from losing unless you will also stop playing. The dice game is also one of my favorite games before when I was really into gambling but then I already stop playing it because it seems so hard to earn money from that and it really makes me disappoint whenever I lose on it.
How can you exactly become so good at throwing dice or playing dice? Isn't that a chance based game? Meaning that no matter how you throw away your dice, once it goes out of your hand, it's going to be out of your control.
There is also some chance if you are the one who will going to throw the chance, if you are going to practice it with the same high of throwing the dice and same speed maybe it will actually work but not that too much accurate.
