Best Winning Chances — How to Value

When you are looking for the best paying online slots, you are usually offered ones with the highest RTP. I’ll also tell you about RTP, but I’m convinced that it’s not the only end even not the main thing that affects your winnings. The variance of a slot game is a revealing mark as well. And I believe that random chance of winning and fair payouts are the most crucial.

What should you know about RTP?

Return to Player (RTP or RTP percentage) is a theoretical metric that describes the expected payout percentage of a particular game. It means that if the RTP of a slot game is 98.1%, for example, you can expect to be paid £ 98.1for every £ 100 you wager (in the long term). The house edge here is 100% - 98.1% = 1.9%. A house edge or a casino advantage is the part of your bet which a casino expects to keep to itself to cover its expenses and make a profit.

Simply put, playing with a higher RTP will give you a better chance of winning in the long run compared to playing with a lower RTP.

Here is the list of slots with the highest RTP you can play on my website:
Ugga Bugga (Playtech) - 99.1% RTP


Mega Joker (NetEnt) - 99.0% RTP


Sure, there are dozens else online slots with high RTP here on Davedealer.com. Just sort the games by Max RTP.

Each game's RTP percentage must be indicated by the provider and operators. In the other case, we can suspect that the game is pirated.

Still, you have to understand clearly the concept of "long term (or run)".It means that this is the expected result for a great number of spins, which can reach millions. Fewer spins might not always equal the desired result.

However, gambling is beautiful due to the lots of surprises that can happen during the game. You may hit the jackpot on an online slot with low RTP or win nothing playing on a slot machine with the highest payout percentages.

High or low variance — which suits you best?

I always advise all players to decide what exactly they want before they choose the game. Do you wish to win a huge amount of money? Or do you want to play just for fun and add some excitement to the game with quite frequent nice prizes? Or you would like to win big but don't want to risk too much?

The characteristics of the slots as variance will help you choose a game that suits you or your current mood best.

Variance (also called variability volatility or dispersion) is a metric that describes how often a player gets a winning combination and how big the wins are. To put it simply, games with low variance will pay out smaller wins more often, while games with high volatility will pay out higher wins, but less often.

High variance slots

High variance slots are good for players who want to win big money. Winning combinations fall rarely, but they are significant.

These are the best high variance slots you can play here:

Keep in mind: to get max payouts you have to make max bets.

Low variance slots

Low variance slots suit those players who appreciate entertainment more than the pursuit of a massive win. Low volatility games pay out pretty little, but due to numerous bonus features, you can get different small prizes more often.

Here are some of the most popular low variance slot games you should try:

You don't need much money to play — min stakes are usually £0.01–0.05 per payline.

Medium variance slots

Medium variance slots may reward you with plenty of low and mid prizes throughout the game. Сhoosing such kind of online slots is an excellent compromise between the wish to win a lot and the unwillingness to take high risks.

You can play these (and dozens of other) beautiful medium variability games on my website:

With reasonable stakes, you may win up to 1000x your bet.

The more detailed classification includes low-med and med-high volatility.

As in the case of RTP, it is essential to understand that due to randomness in the game, the result can be very different from the theoretical indicator.

What else affects winnings?

As already mentioned, all formal metrics are theoretical and based on thousands to millions of spins. In real life, His Majesty chance runs all the games. More scientifically speaking, the result of the game is subject to probability theory as all the online slot games are controlled by random number generators, also known as RNG. In other words, the odds of winning are always the same, which makes casino games fair. Therefore, flawless, certified by an independent company such as e COGRA or iTech Labs, operation of the slot is a must.

Such agencies make sure that online casinos do not violate the stated conditions of gambling and that players receive payments and bonuses in time. Also, to combat fraud, the regulators make certain that casinos do not deceive their customers by making adjustments to the software. They also check that the random number generator is working correctly and that it does randomly determine the winning combinations.

As for me, luck and the sixth sense are as essential as all those real factors described above. You may not believe me, but my gut feeling almost always helps me make the right decision during the game.

How to Choose a Casino with the Best Winning Odds


Any slot game is offered by dozens of casinos. Thus, it’s not enough to find a slot machine with the best odds of winning, is vital to choose the right gambling site.

Using my evaluating method, I selected some excellent casinos where you can find dozens of slot machines which pay the best.

1. Check a casino’s reliability and honesty


Reliability and honesty are the main points I pay attention to when testing and rating casinos.

A trustworthy UK casino has a valid licence from a reputable regulator.

The longer the casino operates without significant complaints from the players, the higher its reputation. The casino owners and linked brands mustn’t be involved in any scandals or accused of payout cheating.

Players personal and financial information is protected by 128-bit SSL encryption.

Mr Green casino is known in the gambling world as “a True Casino Gentlemen” Launched in 2008, licensed by MGA, it has earned players’ trust and won numerous industry awards.

2. Evaluate a mobile version quality


Nowadays, more than half of all players prefer to play casino games on their mobile devices. Thus I impose quite tough requirements on mobile casinos. 

All the games offered at the casino (or at least most of them) must be available on smartphones and tablets, regardless of the operating system. A swift and responsive website and ease of navigation are necessary. The overall mobile experience has to be the same as on PC or better.

Fortune Clock is a mobile-friendly casino. You can use a convenient mobile version of the website, but also you can download a dedicated mobile app and even get a no-deposit bonus for this.

3. Make sure deposit and withdrawal options are diverse


It’s evident that the wider choice of payment methods a casino offers, the more customers it will attract. Still, while evaluating casinos, I consider some more aspects:

  • players' data must be protected; responsible casinos use 128-bit encryption.
  • KYC procedure should be performed only once.

Rolletto casino offers a long list of banking options. As usual, you have fewer ways to withdraw funds, but the choice is pretty wide.

4. Find out if the welcome bonus conditions are acceptable


Each casino’s welcome offer looks incredibly attractive. But don’t rush claiming it immediately. Use my general rules of bonus appraisal: read T&C to make sure that wagering requirements, the validity time, game and payment restrictions, bet and withdrawal limits, etc are reasonable.

The good news for slot lovers is that they can choose the best payout slot machines to play for bonus money. 

Casumo offers a 100% bonus up to £300 + 20 Free Spins, with WR 30x and a min deposit of £10.

5. Test how customer support service works


Every player can come across a problem; it might happen even to an experienced gambler. 

So the high quality of customer service is an essential sign of a superb casino.

The help desk should be available in several ways, and at least one of them (it is desirable that it be live chat)  must work around the clock. The agents’ responses have to be fast and helpful.

At Casino Intense, you can get in touch with support agents via live chat, email a phone call. Their answers are very quick and useful.

Can you really win money on online slots?

Yes, you can. For this, you should play on certified slots at reliable online casinos.

Is the chance to win increased on slots with higher RTP?

Yes, theoretically. However, it is essential to understand that the "long term" means a huge number of spins before the result comes close to expected.

Should you choose high variance slots?

It all depends on your preference. Choose these games if you want to win big. But be ready to win nothing as massive winnings drop rarely.

Will the amount I bet affect the outcome?

Yes, above all. Assumedly, the larger the bet, the higher the chance of a payout. However, you have to bet only the amount that you can afford to lose.

Is gambling on online slots really random?

Yes, it is, but only at secure online casinos which I recommend. At such casinos, all the games and their RNGs (Random Number Generators) particularly, are tested and certified by independent auditors like eCOGRA or GLI.
