Our 7-Step Process for Reviwing UK Slot Sites

How-Do-We-Test-Top-Online-Slot-Sites 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 Select the Perfect Slot Site for You

  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.

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.

Slots Bonus Terms and Conditions You Should Consider

All bonuses come with a set of rules, part of the Terms & Conditions you agree upon when you first sign up. T&Cs are the equivalent of a digital contract, and you clicking on the “I agree” button is the equivalent of your signature. T&Cs can be changed at the casino’s discretion, but any changes regarding them need to be communicated to you in due time.

Different Types of Slot Games: What You Need to Know

Slot sites machine type Distinctive features
Real slot machines These are the games found in top land-based casinos from the UK. They are activated manually through a button or an arm. Obviously, you can’t find them at online slot sites, but they are the base source of the game we play today.
Classic slots These are games that have a classic layout, usually with 3 rows and 5 reels. The paylines are between 10 and 25 at most, and the animations are minimalistic. They are meant to mimic the original games that were built almost a century ago.
Fruity slots The symbols that fall and rearrange themselves are fruits, like cherries, watermelons, etc. Otherwise, the design is very much similar to classic slots. You will find symbols that represent the number 7, which is a stable symbol.
Video slots The animation, fades, music, and all the sensory elements are very modern and high-tech. There is no single theme associated, but the most encountered are adventure-based, historical, mythological, and fantasy designs.
Progressive The pot that increases or decreases while you are playing can grow in size and value when you keep playing. In certain instances, the pot increases while players are betting on multiple sites for UK players, like Mega Moolah, for instance. Jackpot slots are a synonym for the same concept.
Megaways These are slots in which the winning paylines reach numbers that go way over 10000. This is a creation of Big Time Gaming and they have, naturally, gained a lot of traction in the UK online industry.
Jackpot slots Jackpot slots are the ones where the pot increases continually and exponentially to the bets made by one or more players that are actively playing. The terms jackpot slots and progressive slots mean similar things and can be used interchangeably.
VR slots These are slot games designed to be played with the use of a Virtual Reality headset and additional gear. You can find them in VR casinos or in places dedicated to that medium. The game rules and layouts are not changed dramatically.
In-house slots In-house slots are games developed by certain providers, especially for one specific slot site. The site has trademarks over them and UK gamblers can only play them on those specific sites. We let you know which casinos have such exclusivities through each of our reviews.

Paylines 10
Volatility Low
Slot Type Classic slot
Reels 3
Editor’s Rating 5/5

Ugga Bugga is a classic 3-reel, 1-payline slot game by Playtech that offers a straightforward but exciting gameplay experience. We gave this slot a 4.6/5 because of the high potential it serves to UK gamblers. We looked at the features, volatility and theme when making real money bets from multiple devices.

The game has low volatility, which means that through a session of 50 spins, your results will not vary as much. This is an advantage for new starters because they can control their budget and results in a simpler manner. The best feature of this game is the 1000x multiplier.

Mega Joker (Netent) – Best for bets

Paylines 5
Volatility Low
Slot Type Progressive slot
Reels 9
Editor’s Rating 4/5

In Standard mode, bets range from $0.10 to $10 per spin. We gave Mega Joker a rating of 4.5/5 rating because we believe it is a high quality progressive slot created by a very popular UK provider. One feature that represents a strong advantage is how well the game optimizes for mobile devices. The retro theme and the feel of a classic, land-based game translate well to smaller smartphone screens.

The best features we’ve discovered are the special Supermeter and Gamble modes, which change your display and how the game functions and produces outcomes.

1429 Uncharted Seas (Playtech) – Editor’s choice

Paylines 25
Volatility Medium
Slot Type Video slot

Proven Tips for Playing Slots Online Wisely

How-to-Play-Online-Casino-Slots-on-Online-Casinos

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.

Should You Ever Bet the Maximum? Here’s When It Makes Sense

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.
