How We Test the Best Slot Sites (7 Steps)

Transparency is a key part of our review process. To stay true to ourselves, we present in detail how we work for UK customers.

The UKGC mainly focuses on:

• Providing responsible tools
• Pre-empting minor gambling
• Offering an overall reliable experience
• General prerequisites for safe play at slot sites.

Step 1: It All Starts with a Valid Licence

The United Kingdom Gambling Commission guarantees that slot sites follow strict legislation. The terms are fair, the games are not pressuring you to play too fast, you have access to responsible tools, and your overall time spent there is positive.

A website licensed by the UK Gambling Commission always prevents minors from gambling. Thus, your children will be protected too.

Step 2. We Check Slots Sites’ RNG

Most top-rated slots sites with a UKGC license also have their RNG systems vetted by independent third-party auditors.

We will look for online slots sites with RNG fairness seals from:

• eCOGRA
• Gaming Labs
• iTechLabs

Those add a layer of safety regarding the software and engineering of the games we have no way of testing ourselves.

Step 3. We Dig Deeper Into the Volatility of Slots

Slot sites game volatility means the likelihood of the result of a spin to be widely different each time.

There are two volatility phases:

• Low volatility – the game payout is the same range almost all the time, and the sums are never too high as compared to your bet
• High volatility – the game payout may be significantly higher than the bet, even if the bet was quite insignificant

We can check that by going in the game’s settings. In the rare cases when that is not public in the open game, we test it for two weeks and make our own assessment.

Step 4. We Never Miss Looking at the Paylines

Paylines are the embedded winning combinations that, when hit, will result in a winning bet.

The number of paylines must always be written in the game settings. Sometimes, the original number may be expanded in certain conditions, which fall in the special features category.

Step 5. We Analyse the Unique Features of the UK Slot Sites

Since there are thousands of games featuring different types of slot machines created yearly, the best ones need to have catchy features. We analyse them and tell you which feature is the best.

Here are the main ones:

• Multipliers – the number of times your bet result will be multiplied randomly
• Wilds – random symbols that appear and expand your bet
• Scatters – random symbols that create a payline where it wasn’t

Step 6. We Proceed with Making Bets

We test all of the settings and details with real funds. That is the same method you would use when playing, and we need to make the same steps you do so we can be your trusted guide to slot sites.

Step 7. Overall User Experience on Mobile & Other Devices

Between 80% and 90% of online gambling is nowadays done on mobile phones and sometimes mobile tablets.

Thus, we focus on those types of devices a lot when we test the best online slot sites. We can then see if there are glitches and how they might affect your sessions.

Why Do We Use All These Testing Methods?

CasinoAlpha experts want to bring you the top gambling sites that we confirm to be good first. We need hand-down testing and methods that are available to you to bring you the safest options for slot sites.

We use objective testing and a team system to remove bias on any opinions we might have.

How to Choose the Best UK Slots Sites

1. Utilize CasinoAlpha’s monthly updated database of slot sites.
2. Read our slots site reviews and additional bonus pages to learn about their offerings.
3. Register by following our instructions.
4. Complete KYC as quickly as possible to save time while conducting transactions.
5. Play securely and adhere to the attached Terms and Conditions.

Latest UK Slot Sites

When making our selection of slot sites, we start from a baseline of high standards for new casinos in 2024, to be sure they reach our safety and playing standards.

For alternatives, explore our reviews of WatchMySpin and SpinRio if you feel Barz doesn’t live up to your expectations. While all our picks are thoroughly tested, you are free to explore all of the UK’s top new 2024 slot sites.

JeffBet

Type of Bonuses Available at UK Slot Sites

These are just a few subtypes of the best online casino bonuses that we work with daily. We know that each player can find a type that fits their needs, whether it is about slots with free spins, or live casino promotions.

Be Aware of the Following Aspects

1. Each slot sites bonus has unique terms and conditions attached. You need to stick to it and respect it. Otherwise, you risk losing the bonus or the funds derived from it.
2. Cashing out before finishing wagering, when the issue is present, is impossible and may result in you losing your bonus.
3. Pay attention to the exclusive slots sites where the spins apply to avoid your bonus being voided.

Take time between sessions and bonuses for your own mental health.

Advice for Safe Jackpot Play

1. The probability of winning the jackpot is tiny, so keep your hopes low.

4. Progressive slot machines have lower chances of winning than classic lottery tickets.

How to Play Online Slots – Basic Steps

Basic Steps to Play Slots

Your first and most vital step is to know the game rules and what each symbol or feature does.

The second step is to calculate a fixed slot play budget. Once you have one, never exceed it.

CasinoAlpha’s perfect budget formula is to first figure out your monthly pocket money, after bills, and savings accounts. Out of that sum, 10% can be used for gambling. We highly recommend you don’t spend more than that.

The third is to choose a casino and a game.

The fourth step is to read the game specifications and rules once you launch it. Then, you can just play.

How Do Online Slots Actually Function?

They are software that is created on the base of complex code. Their results are based on Random Numbered Generators, so there’s no room for rigged outcomes in the games.

How Do Online Slots Pay Real Money?

All of the games on UK online casinos can pay out real money if you use real funds and hit a payline.

Real funds play in the UK is tied to confirming your account and finishing KYC to prove you are of legal age and your payment services are legitimately yours.

Our Recommended Strategy when Playing at Slot Sites

Nothing is more important than managing your slot’s site bankroll wisely. There’s no complex strategy for the game itself, and therefore, the way to manage your funds is your pinnacle point.

After setting a budget, you need to:

• Know the game well enough.
• Don’t bet high sums in general.
• Examine the paytable and know what symbols you’re playing with.
• Take breaks often.

When, If Ever, Should You Bet the Maximum Amount?

Betting the maximum sum allowed may get you closer to activating the jackpot special feature of certain sums. That, in turn, may give you free rounds, which essentially are you playing more with no spending.

But the probabilities are low for that to happen and are disproportionate to the investments. So, don’t do it more than a few times a year.

Payment Information & Advice

Here is CasinoAlpha’s guidance on slot site payments:

1. Don’t make high payments to slots sites you’re new to; play slots with a minimum deposit and keep it affordable.
2. Use payment methods that you are comfortable with. Look up e-wallet choices like Neteller casinos to shorten withdrawal times.
3. Don’t pick options that apply fees that obviously affect your bankroll.
4. Finish wagering before cashing out.
5. Ensure you have no pending transactions before engaging in another one.
