I took a stroll this evening on my Chrome Browser looking around at dice mechanics and popped in on some juicy articles on Dice Theory.
Two articles have stated some interesting results.
“However, new theoretical models and high-speed movies of dice rolls of numerous shapes and sizes confirm this is not strictly the case. They show that dice thrown with a 1 on the top are slightly more likely to land as a 1 than as the other values for every type of the various kinds of dice they studied. But at the same time, it’s usually too hard for someone to predict the outcome of the throw of a single die–you’d have to know the starting conditions of the throw and its environment so precisely that for all practical purposes, the result could be considered random.”
Source: Dice Rolls are Not Random
Oh and there is a nice rebuttal by someone claiming 25 years of experience in the replies.
“I know this will sound egotistical, but this whole paper is bogus pseudoscience. Seriously. NO ONE rolls dice from a stable single face on top position, and if they do they get called on it every time. When using a tower or a cup or other such thing, or even shaking them in your closed hands, the results will be completely unpredictable. You took a random thing and applied a single version of “rolling”, if you can call it that at all, and of course the results are predictable! Problem with your study is, that’s not how dice are ever rolled! What a waste of time and energy this stupid study is…”
So with this said, you might want your players using cups or closing their hands and shaking them.
A second article speaks on the predictability of dice throws.
Quote: “‘Theoretically the die throw is predictable, but the accuracy required for determining the initial position is so high that practically it approximates a random process,’ said Marcin Kapitaniak, a Ph.D. student at the University of Aberdeen, Scotland.”
And Comments section (which I love) quote: “Chaos is just the inability to know everything and therefore a lack of knowledge, which is not a mathematical issue, but a practicle one. Probability and potential outcomes just tease us humans like a ball of wool teases a kitten. Everything is always random. To be looking at an article about Polish scientists suggesting that the rolling of dice can be predicted was never likely to ever happen, ever, in the whole life time of the universe. Yet it did. The actual likelihood of me typing these words was a certainty having done it, but infinitately improbable to predict by someone last week. The occurance of anything always suggests that it can happen again. We are here so there are definately other people somewhere in the Universe because nothing can be so impossible as to have 9 billion beings in one place and there be none others in such a vast universe. This is the probability of concept. Rolling dice and the chance of coins landing on their edges are the probability of risk.”
One more helpful link. There is a vast collection of virtual dice online. Those who use True Random Numbers are the ones you want to use.
Lucky for my app maker and I Adobe uses True Random Number Generator. So if you need a dice roller for your android phone, check out this cool Steampunk Dice Roller here.
This article is not just a plug for my free app. I really do want people to understand how a person rolls real dice can affect the role creating non random results. Also there is such a thing as a true random number generator online. So check it out.
