Is it safe to play free slots online?

Whether slots are safe to play (or not) depends on the licences and security processes employed by the casino or site you are playing at. All slots available for free at trusted UK online casinos are tested and approved by the UK Gambling Commission (UKGC), which is the same institution that licences online casinos. 

If you want to know more about keeping yourself safe while playing online slots then we recommend going through our Responsible Gaming page.

Are free online slots legal in the UK?

Free online slots are legal to play in the UK, if with an important requirement – the site offering the free slots, regardless of whether it is an online casino or not, needs to first verify your age before allowing you to play. This is due to regulations set by the UKGC back in 2017 that make such age verification compulsory in order to ensure children and teenagers under the age of 18 are not exposed to gambling content. 

If you’re a registered online casino user, then you can safely play the slots in free or demo mode, should the online casino allow you to do so. In the case of sites offering free slots then you will need to verify your age through free services such as AgeChecked

Why do casinos allow you to play for free?

There are two main reasons why casinos allow players to try slots for free. First, it’s to give customers a chance to try games before they actually spend money on them. That way, one can confirm that they actually enjoy the slot and its mechanics. Second, free slots are a means to promote safe gameplay, since players will still be able to enjoy slots without spending their money. 

Why play free slots online?

As mentioned above, playing online slots for free is an opportunity to try out a game without spending your money! This way you can test out special features and get a general feel of the game before actually staking money on it. This can be particularly helpful if you are completely new to playing slots.

Can you make money by playing free online slots?

While most casino sites allow players to play slots online for free and they may at times be rewarding, such gameplay sessions don’t lead to real money payouts because they are for entertainment purposes only. That said, some casino sites offer no deposit free spins bonuses that allow you to boost your gameplay sessions.

Best no deposit free spins online slots 

You can enjoy some of the best online slots in the UK for free with a no deposit bonus. This admittedly rare promotion is exactly what it sounds like – a bonus given by a casino with no deposit required. Better still, unlike playing slots in demo mode you can potentially win real money by playing with a no deposit bonus! 

That said, make sure you are familiar with the terms and conditions of any no deposit bonus you accept from a UK bonus. These cover everything from the expiry period of the bonus to any wagering requirements involved.
