Controlled shooting or dice control is when you try to set and throw the dice, in the same way, every time and hopefully avoid the dreaded seven. There are multiple complicated ways of setting the dice in your hand with different combinations on top; this is supposed to keep the seven from appearing when you throw it.
Another critical element of dice control is the way you throw. Your throw needs to be as light as possible but must still touch the back wall, and it must be consistent every time.
This is all very difficult to achieve, and, ultimately, there's no statistical evidence that it even works. Although many prominent coaches and blogs might tell you it works and some experts have posted articles explaining why they think it works, it's impossible to know whether it really does.
The rubberized diamond walls, along with the pure randomness of a dice throw, make the outcome impossible to predict, even with some of the most involved formulas and algorithms. The way you hold or throw the dice isn't going to affect that randomness at all.
New Jersey grandmother Patricia DeMauro proved this point by setting the world record for most throws with 154 consecutive tosses lasting over 4 hours. She didn’t even have a clear idea of how to play in the first place. She said it was only her second time playing without knowing the rules. Makes you wonder why all these "experts" spend hours practicing the perfect dice throw.
