    How RTP Relates to the Highest Payout Online Slots

    If you’re new to online gambling, you will hear a lot about “RTP” and will wonder what it means and what is its significance.

    The initials “RTP,” stand for Return to Player. This phrase basically tells you how much money you can expect to win back when you are playing a particular game. It’s not restricted to slots, by the way. It applies to all online gambling games.

    But before you get too excited when you see RTPs like the 99.07% awarded to Ugga Bugga, you need to understand something. Yes, it is one of the best paying online slots UK casino offer, but the RTP measurement is taken over a prolonged period of play – millions of spins in fact.

    So, even though you might play a game with an RTP of 99% or more, you are not likely to see that sort of return if you only play for a few minutes. But, having said that, the best payout slots online bear one thing in common with all games – top payout or not. The outcome of all spins is determined by the online casino’s RNG.

    RNGs and How They Work

    RNG stands for Random Number Generator. It is a device that comes up with a random result which determines where symbols lands where in a machine’s window. The key word is “random.” In other words, the result is unpredictable. It why the only way an RTP can be calculated is over millions of spins. The number and value of the winning lines landed is compared to the number and value of spins taken, and it is shown as a percentage.

    The Licensing and Auditing of Best Payout Slots Online Casinos

    Most online gambling platforms that welcome players from the UK are licensed by the UK Gambling Commission or the Malta Gaming Authority. Both are highly respected license providers, and one of the things they monitor is that all of the brands they license have their RNGs independently audited and fair game certified.

    Amber Spins CasinoGibraltar Regulatory Authority, UK Gambling Commission
    Hunky Bingo CasinoGibraltar Regulatory Authority, UK Gambling Commission

    The companies that carry out this auditing are organisations like eCOGRA, iTech Labs, and iGaming Labs. They also do RTP tests for software providers and casinos. So, whenever you see one of these names posted on the highest paying online slots websites, you know that online gambling industry best practice is being observed.

    Because games work on a purely random basis, RTP is as good a guide as you can get to the best online casino slots payouts. But the odds are always loaded in the House’s favour. So, if you do get ahead while playing, and it happens quite often, it’s best to quit while you are ahead, and play again at another time.

    Best Paying Slot Machines Casino House Edge

    You will also come across the expression “house edge” when gambling online. It’s the same thing as RTP but looked at from the House’s rather than the player’s.

    While an RTP of 99% indicates that when gambling £1,000, a player hopes to have £999 returned to them through winnings, from the casino’s perspective, they can expect to retain £1 for every £1,000 wagered. It’s the difference between the amount of money a casino keeps from that which is wagered, as opposed to the money a players wins from what they wager. The same thing but from a different angle. It’s not just about RTP though.

    The Variance of Volatility of the Best Paying Casino Slot Machines

    Whereas RTP is an indicator of the amount of money a players can expect to get back over a long session when playing a particular game, variance or volatility is a measurement of risk. A sgame with high volatility will present you with a long run of low paying wins, followed by bigger wins at random. A low variance game means you win more often, but smaller amounts.
