Randomness In Gambling

Online gambling is becoming more and more popular, especially with recently legislation changes in certain states, and with this increase in gambling, many players find themselves wondering how randomness works – and whether a game is truly random.

In this post, I’m going to cover the randomness in online gambling, as well as how to determine whether a website you’re playing at is using a fair and unbiased RNG (random-number-generator) to determine their wins. So first of all:

A random-number-generator is – as the phrase dictates – a computer that spits out a random number, so that a game can be decided. For example, if you’re playing a game of Blackjack, the next card that comes out of the Blackjack shoe is determined by a random-number-generator. The same applies to Video Slot games. A random-number-generator will determine which symbols appear on each reel, at random.

An online casino will usually rent their games from a software provider, who actually make and maintain the games. That said, it doesn’t change the fact of how the games actually work, and the moment you press the spin or deal button, the random-number-generator gets to work, and returns a number, generated completely randomly. This random number will then be used to determine the outcome of the game.

While no computer is capable of producing a true 100% random number, random-number-generators are extremely fair, and all casinos that offer games to players from the United Kingdom, as well as any country around the world, must submit their games source code to independent companies to verify they are indeed random.

This means a random-number-generator goes under intense scrutiny to verify that it is actually random, and this way, you can enjoy playing safe in the knowledge that the game you’re choosing top lay is fully random.

One of the most common complaints I hear from players is that they lose a hand multiple times in a row, or don’t have a win on the slots for a long time.

While it can be tempting to blame this on the random-number-generator itself, it’s important to remember that a random-number-generator has no memory – each time it’s assigned to produce a new random number, it does just that – previous play does NOT dictate the outcome.

This means – that while very unlikely – you could lose – or win – 1,000 times in a row, since the random-number-generator has no memory and is not attached to previous play. The exception to this rule is with certain fruit machines, where it’s not random – but you don’t generally find these online so won’t have to worry about that.
