Below you'll find info about different types of slots, aimed at British fans of a particular slot category. 

New mobile slots

All casinos and games are launched on mobile as well as desktop. A heavy focus on mobile usability has become the norm among game suppliers.

New mobile slots are optimised for the small screen and thanks to HTML5 technology, run smoothly on every platform. In addition to playing in an Android mobile casino, you can try new slot games for iPad in every new UK casino.

New video slots

Launching new video slots games is the mission of most game studios. Online video slots are modern versions of the old fruities. The latest video slots online usually feature:

New penny slots

New penny slots can be played with the smallest denomination available in the UK: 1p per spin. Many new penny slot machines have the option to choose the number of active paylines. They are getting rarer, but you can still play new slot games with a penny.

You can adjust your chance of hitting a winning combination on the next spin. Remember that by increasing the paylines you'll also up your bet size.

New bonus slots

While playing the main game may be entertaining, bonus games and free rounds tend to hand out considerably better wins. This is especially true with new bonus slots.

In addition to depositing and playing with your own dough, you can play slots with bonus money. You can choose between:

New slots and responsible gaming

Gambling is always risky and especially slots. These games are designed in a way that the player will keep on playing until they lose.

It is good to understand how slots work and what the developers are actually doing. A feature that makes you collect symbols over several spins is simply there to make you play more.

Slots, as well as other casino games, have a negative statistical outcome for the player. This means that with every spin, you are likelier to lose. The more you play, the higher chances you have of losing everything. This is why the games are designed so that you will keep on playing.

Goodbye Flash, Hello HTML5

If you're a mobile player, you can skip this part as the Flash support ending doesn't have much of an effect on you. But, if you are a desktop player, you might notice some slots not being available anymore.

Before mobile gaming was a thing, just about every casino game was built with Flash. It was easy and convenient, though it did have some security and performance issues even back in the day. However, smartphones got more advanced and completely changed the way we play.

As of January 2021, Flash was officially declared dead and Adobe blocks any Flash content from running on Flash Player.

As per Adobe's news of Flash's demise in 2017, many game suppliers took immediate action. While they started converting their older selection to HTML5, others just abandoned their old products.

In the process, several older casino games simply stopped working on desktop and only left the ones based on HTML5 running as usual.

Luckily, there are plenty of new slots to replace the mothballed favourites of the bygone days. Many of the classics have been revamped with modern twists and even have higher payouts, too.


In total, there are tens of new slot games launched every month. The release pace between game suppliers varies greatly. Big companies usually push out new titles every week. Smaller studios concentrate their efforts on fewer game launches that take place only once every few months.

The big providers are able to fill out the calendar with frequent launches. Although there may be a couple of re-skins and filler games in the mix to fill the quota, the overall quality of online slots is solid. However, you can often see which of their new slots have more effort and originality behind them.

With so many new slot machines to choose from, trying all the latest titles from every casino game supplier may prove challenging. Here's what you should consider when choosing new slot machine games online:

  • Reputable license
  • RTP (payout percentage)
  • Volatility
  • Game supplier
  • User interface
  • Theme
  • Graphics & sounds
  • Special features
  • Bonus game

You can see all this information on Bojoko's slot reviews and use our handy slot sorting and filtering tool to find games to suit your preferences.

Play new casino slots in the best UK-licensed online casinos, vetted by the Bojoko community.

There are many reasons why many new online slot sites have quickly became extremely popular among online casino enthusiasts. Many people just want to try something fresh every once in a while. Here are some more reasons:

  • New slot sites are innovative. Newcomers need to offer something original and unique to stand out. Gamification, innovative features or state-of-the-art mobile version are key elements.
