Since the inception of online casinos in the 1990s, the industry has gone from strength to strength. The ubiquity of high-speed internet, alongside significant advances in the technology behind the scenes, means that games such as ライブ ルーレット (or “live roulette”, for non-Japanese speakers) have become increasingly popular in recent years.
But how exactly does the tech behind roulette (and other games) work? How can visitors to a site trust that the operator will use a fair method of calculating winners and losers? How can they know that the deck isn’t unjustly stacked against them? Well, the whole arrangement is governed by RNGs and RTPs, which ensure that every bet laid is treated with transparency and integrity by the operator in question. Let’s take a closer look at those terms in isolation.
What is an RNG?
A random number generator (or RNG, for short) is a computer device which randomly generates numbers. They are often regarded as the brains which power online casinos, since they are responsible for the outcome of the spins on roulette wheels and slot reels alike, as well as which cards will be dealt when playing online table games.
The RNGs which power today’s online casinos are no different in theory to more primitive versions of themselves, such as coin flipping and dice rolling. The only difference is that the possible permutations of an RNG outcome are far, far greater than either of the aforementioned alternatives, which work to make the mechanics of online gambling truly random.
What is RTP?
Return-to-player, or RTP, is a numerical value that each online casino game carries and indicates the percentage of money wagered that a punter could expect to win back over an extended period of time. It’s important to note that RTPs are not just calculated from the activity of a single player, but rather millions of different turns from across countless players.
As such, a game which carries an RTP of 95% means that for every $100 a game takes in, it will give out an average of $95 back over time. It does NOT mean that a single player should expect that kind of return every time they play the game – otherwise they would have no chance of winning big and there would be no point in playing at all.
Can you trust RNGs and RTPs?
Some people are concerned that both RNGs and RTPs are mere window dressing, and that a casino site will not operate transparently nor fairly when determining who wins and loses. While there are a tiny minority of unscrupulous sites which may do this, the vast majority of online casinos are licensed and regulated to ensure that they provide their customers with a completely fair gambling experience.
You can make sure that you avoid untrustworthy sites by choosing a casino which has a strong reputation behind it. If in doubt, you could also do your homework by reading up on reviews from customers who have previously used the site to make sure everything is above board.
Conclusion
Technology like RNGs is making the games and slots at online casinos safer and fairer than ever before. And since not all games carry the same RTP, it makes sense to seek out those with offer higher returns than their competitors to maximize your chances of winning.
