Online slots are ‘Hot’ or ‘Cold’ - False

This myth is the most common one amongst land-based and online casino players. It is believed that online slots can blow ‘hot’ or ‘cold’ – a cold slot is one that doesn’t pay out winnings often whilst hot slots pay out frequently. Online slots, as well as Las Vegas slot machines, use Random Number Generators meaning that the odds of winning is random, whatever slot game you are playing.

Online slots are rigged - False

Online slots are subject to heavy regulation from the licensing jurisdictions they are found in. In the UK for example, all online slots and online casinos are bound by the conditions of the UK Gambling Commission ensuring a fair and transparent playing environment for online gamblers. Whilst slots do use Random Number Generators, the outcome of each spin is purely luck. You should play at a licensed online casino in the country you are in to ensure a reputable product. If in the UK, look out for the Gambling Commission logo at the bottom of an online casino’s website – it will have a link to the UKGC license. If you cannot find it or it’s not there, run a mile!

Playing at ‘Max Bet’ will increase your chances of winning – Partly True

Slots players think that increase your bet or stake size will influence an online slot’s ability to pay out. Whether you are playing at minimum or maximum stakes, the odds of winning are normally exactly the same. In some progressive jackpot slots, the chances of winning the jackpot increases the higher your stake. This is myth can be true! Certain Barcrest slots offer a higher RTP% when playing at increased stakes so theoretically you can win more by playing using a higher bet amount.

The RTP % means I will get exactly that back – Partly True

If an online slot has an RTP of 96%, it theoretically means you will win back £96 if you were to stake £100 – giving the online casino a 4% house edge/margin. Whilst this is true, the RTP% if based on a certain number of spins (into the millions) – whilst you may win £1,000 from a £1 spin, lots of other players will lose that amount to compensate for your win. You getting that big win is completely random. If not, no-one would ever win at slots and wouldn’t play them.

Playing with a casino bonus affects my winning chances - False

The particular online slot doesn’t know if you are playing with a casino bonus or not – the slot game only sees money being wagered with the outcome being completely random. A casino bonus can help you get lucky and win big which can lead to your completing the wagering requirements and cashing out the bonus and any subsequent winnings.

Online slots pay out more at a certain time of day - False

The outcome of a spin or set of spins is random and determined by Random Number Generators – what time of day you play an online slot has no bearing on the RNG. If you fancy playing slots on your mobile device in your pyjamas at 6 in the morning, do so!

The longer my losing streak, the higher my chances of winning big - False

All slots use Random Number Generators – you may be unlucky and play 500 or 1,000 spins without winning. Your very next spin could result in a life-changing win. Or not – you could lose again. It’s important that you gamble what you can afford and not chase the next big win – it might not come in your current session.

A jackpot has just been won, I won’t win now - False

Many players like to play progressive jackpot slots – this gives players to win a life-changing amount of money. Slots like Microgaming’s Mega Moolah and NetEnt’s Mega Fortune have paid out 8 figure sums before from just 1 spin! If a progressive jackpot is won, the chances of winning it are the same if playing straight away or at a later time – the jackpot will be lower though if you play right after a big win has been won.

I’ve missed a big win narrowly, a big payout is due soon - False

There are so many close calls where you miss a big payout by 1 symbol or 1 payline – this is the nature of online gambling. This doesn’t necessarily mean that you are due a big win soon though – the outcome is random. Let’s just hope that big win does come soon though.

Loose online slots are hidden away at online casinos - False

A loose online slot is considered to be a game that pays out more frequently that other slots – it’s also known as a ‘hot slot’. Online casinos don’t hide them away because they don’t exist – an online slot game may have paid out millions recently, but it can still carry on paying big if a player gets lucky. The outcome is completely randomised.

Using the AutoPlay function affects my winning chances - False

The AutoPlay function allows players to spin away on a chosen amount of spins without having to initiate the spin every time. Available on most slot games, the chances of winning or losing as exactly the same. Some slot machines offer a gamble feature when you get a winning combination – the AutoPlay function normally continues spinning and not offering you the gamble feature.

Online Slot Myths Verdict

There are 2 slot myths that are partly true.

1. Playing at max stakes/bet on certain online slots can increase your chances of winning
2. The Return to Player % is set amongst a certain number of spins – in theory, you’ll win the RTP back

However, as mentioned many times, the outcome of an online slot is completely random as they use Random Number Generators. You may be unlucky and lose 1,000 spins in a row but then could win the maximum payout on your 1,001th spin – you could also win a life-changing sum of money on your very first spin. There is no way to determine this and it’s down to pure luck. What this does mean though is that playing online slots is exciting and what keeps us coming back for more – just remember to gamble with what you can afford.

Online gambling is legal in the UK

Playing online slots in the UK, or online gambling in the UK, is legal and part of modern culture. The UK has always had an affinity with sports betting as there are many bookmakers with betting shops across the UK – you’ll see a betting shop on most high streets. As a result, online gambling is very popular and accepted. You need to be 18 years of age or over to play your favourite slot games online. If you want to participate in lottery, you need to be 16 or over.

No tax on winnings

When you win on an online slot, there are no taxes to pay – in fact, winning from a licensed UK gambling operator will be subject to no taxes whatsoever. If you were to win £10,000 from 1 spin on your favourite slot, the amount will be yours to keep. Any tax is paid by the gambling operator, or online casino, in this case.

Bound by the UKGC

Playing video slots or any other casino game online is bound by the conditions of the regulating body, the UK Gambling Commission. Launched in 2005 in thee Gambling Act 2005, the UKGC (as they are known) were awarded full power of the gambling section in 2007 and 2013 for national lotteries. Their role is to license and regulate the people and businesses that provide gambling in Great Britain. These are their objectives:

• Preventing gambling from being a source of crime or disorder
• Ensuring that gambling is fair and transparent
• Protecting children and other vulnerable people from harm and exploitation by gambling

All online casinos offering their services to UK players must be licensed by the UKGC – furthermore, all online slots need to be from slot providers that are licensed by the UK Gambling Commission. This ensures that the slot games you play are regulated, trustworthy and fair. All casino games need to use Random Number Generators so the outcome is random and indeed fair.

Display of UKGC license

All licensed online casinos must display that they are licensed by the UKGC and provide a link to the UKGC’s license register. You will normally find this at the bottom of an online casino’s website. On the link, it will take you through to the UKGC’s website where you’ll see the operating address, website domain names under the license, trading names and current license status.

When it comes to slot providers like Playtech or Net Entertainment for example, they too will display their UKGC license on their websites. If a reputable online casino offers slots from a certain provider, they are sure to be regulated and have a valid UKGC license to offer their slots to UK players.

Penalties for illegal gambling operators

If you see an online casino without a Gambling Commission license, they are acting illegally – this will result in action taken against the operator as well as payment facilities being withdrawn/removed (such as PayPal, MasterCard and Visa).

Unfair casino bonus terms protection

The UKGC have reviewed the Terms & Conditions for casino bonus from UK online casinos. Carried out with the Competition and Markets Authority in June 2017, UK players can now walk away with the money they deposited if they sign up to a casino welcome bonus.

Online casinos are not able to confiscate funds or impose charges for customers requesting to withdraw the money they deposited for example. You will see that all casino bonuses and offers have clear Terms & Conditions displayed from the get-go – all players can see the requirements of an offer before they take it up.

Furthermore, players don’t need to take part in publicity or advertising activity for an online casino before they can withdraw their winnings. Daily, weekly and monthly withdrawal limits have also been looked at with online casinos not putting in unreasonably low limits to stop customers from withdrawing their full winnings right away.

Safe player funds

Regulated and licensed online casinos must hold player funds in a separate account from operating accounts. If an online casino was to go bust, the players funds would be safe as they money is held somewhere else. This means your money will always be safe and paid back to you if anything was to ever go wrong.

Responsible Gambling measures

You may have heard the term Responsible Gaming quite a lot if you play slot games online. It is a concept that applies to online casinos in the UK that ensures they offer the highest quality standards and a safe experience for their customers. Online slots players can use a number of tools so they enjoy playing their favourite games online safely – some of them include:

• Deposit Limits – customers can set a limit on the amount they deposit for a chosen period. It can be daily, weekly or monthly. Changing a deposit limit will require a 24-hour cool-off period though normally.
• Wager Limits – customers can choose an amount they don’t want to wager over – once it’s reached, the player won’t be able to play until the chosen period is over
• Reality Checks – these give players reminders of how long they’ve been playing for
• Profit & Loss – customers will be able to see how much they’ve won or loss for a chosen period
• Reverse Pending Withdrawals – customers can disable or enable the ability to cancel/reverse their pending withdrawals/cashouts (Paddy Power Casino offers this)
• Cool Off Periods – players can choose how long they would like to suspect access to their accounts
• Self-Exclusion – this allows players to blocked from playing at a certain online casino or a certain product
