It’s all in the Wrist.. Dice – Love them or Hate Them

I have a variable relationship with Dice, like everybody I suppose – however, combined with my enjoyment of winning ( I’ll cover that in a different post), paranoia about continually rolling ones and general glass half empty attitude – I find my relationship with dice, especially D6s a negative one.

Why is this?

Why do I roll more ones than everybody else ? do I roll more ones than everyone else?

Science

Apparently, a study has found that you are statistically more likely to roll the number that is on top the dice.. could this be why I roll so many double ones? certainly on re-rollable dice -I’ve picked up the dice ( with a one on the top) and just re-rolled it in a sad, defeated dropping motion, invariably getting a one !!! – Bloodbowl I am looking at you.

The initial position of the die,” Tomasz Kapitaniak,of the University of Lodz in Poland, wrote to me in an email. Small changes in the position can significantly affect the outcome. Other factors are less significant. “The air resistance can be neglected,” he said.

However, he quickly added, “friction is important.”

With a high-friction table, in which the dice can’t slide across very easily, the dice tend to bounce around more times, tumbling and twirling, and making the results harder to predict. With a smooth, low-friction, or soft table, the dice tend to bounce fewer times.

Even bouncing doesn’t always mix things up. The high-speed video showed that dice frequently did not change their face even after a bounce.

Could gamblers use the knowledge from this paper to their advantage, by placing the desired value of their roll as the highest-lying face of their die?

“I don’t know how to use it practically in casino,” Kapitaniak wrote. Players would have to know everything so precisely–most importantly, the exact position of the die–to be able to predict the results with certainty.

On the other hand, casino operators won’t ever be able to achieve 100% random rolls with dice. They often drill the pips–the little dots in dice–and fill it with uniformly weighted material in efforts to make all sides of the dice equally probable to come up in a roll.

“Drilling the pips…gives the symmetry in the die but symmetry is not enough” to make it random, he said. “[The] top face will always be more probable.”

So not random, so does chaos affect dice rolling?

Apparently for chaos theory to have an impact the dice would need to bounce an infinite amount of times, so we would require a frictionless surface, for the dice to roll on and therefore require the dice never to lose any energy.

So keep the dice on its face you want to achieve, and use a nice rough surface to bounce it on!!

In order to try and understand my own dice rolling I will be keeping a log of every dice roll I make in every game !! perhaps I am not rolling ones all the time.
