What’s an Instant Play Casino?

At an instant casino you can access the game lobby without having to download software. All you need to do is run the casino in browser and sign up for an account to get started with your online gambling experience. Do remember that you must be over 18 years old to play in the UK.

Because this requires no installation, you don’t need to save anything to your device – which means no space is used up. Also, this allows you more flexibility since you can gamble from wherever you are, and even from different devices. Since there’s no app download, you can change your play from desktop games to mobile slots at any time.

Why Should You Use an Instant Play Casino?

While playing at a no download casino is great if you want to access your favourite real money slots and casino games instantly, there are still a couple of things you’ll want to know about before getting started.

Have a look at our table below to see why our team of experts highly recommend instant play online casinos, along with some reasons they might not be for you.

Pros

✅ You’ll have the best UK online casinos at your fingertips – access them directly in browser whenever you want.

✅ You won’t need to slow down your device by installing yet another app – play with no download required.

✅ You can play at home from your desktop computer or on the go from your tablet or smartphone – all you need is a URL.

✅ All UK gambling sites are available in instant play mode. Unlike download casinos, they’re not subject to the operator providing downloadable software.

Cons

❌ While you’ll have instant access to the newest online slots, you won’t be able to play games which require more powerful software to load.

❌ Even though you don’t need to download casino software, you still need to ensure that your computer or mobile software is up to date.

❌ You’ll need to log into your account every time – especially if playing from a shared or public device.

How Does an Instant Play Casino Work?

Before Adobe Flash came on the scene in the late 1990s, all gambling sites used to be download casinos. This is because there was no technology available to power game animations and casino websites in browser.

Nowadays, it’s the complete opposite. You won’t need to download any site software with instant casinos. But as mentioned, your browser will need some kind of plug-in to run online gambling games. Still, this software is usually pre-installed on modern devices, and you won’t need to do anything yourself.

You can find the most common ones listed below.

HTML5

After Adobe Flash was discontinued in December 2020, HTML5 took the top spot. It's very easy to use since web browsers enable it automatically. HTML5 supports immersive gameplay as well as loads high quality content very fast. This makes it perfect for live dealer streams, among others. It’s also enhanced mobile gambling since the same software can be used by Apple, Android, or Windows devices.

JavaScript

This is the least common option you’ll find at instant play sites since it runs games slower than other software. Also, while JavaScript is generally pre-installed on devices, you’ll need to check for updates to load casino games seamlessly. However, it does have the advantage of being compatible with most platforms and devices.

Adobe Flash

Adobe Flash is no longer supported, but before its end-of-life date in 2020 it was the most popular plug-in used to load instant play casino games. Online casinos favoured this software since it was free and simple for users to enable on their device and compatible with a lot of browsers. However, it faced a lot of security issues and wasn’t supported on Apple devices.

Are Instant Casinos Safe?

Yes, you’ll be safe if you pick a trustworthy and licensed instant play casino. Look for a reputable operating licence from the UK Gambling Commission. A reliable site will also have other security measures. These include fair and tested games, as well as trusted payment providers. You’ll also find responsible gambling tools in place, to ensure that you’re in control of your play.

You will have to be careful though when sharing a home computer or tablet, or using a public device. While saving data – such as your username and password – allows you to log on faster in browser, you shouldn’t do so if it’s not your personal device.

Ensure you’re being responsible if there are children around at home. Don’t allow others to access your information and payment details if you’re gambling from a public computer. When your session is done, sign out of your casino account and close the browser.

What Games Can I Try At an Instant Play Casino?

You’ll find many instant games available, with some sites featuring titles from 30+ providers. Whatever it is you like, you’ll be able to play with no waiting time at an instant casino.

Online Slots

Do you prefer a classic experience on 3 and 5-reel slots? Or a more interactive gameplay with features and bonus rounds? Or taking a chance on progressive jackpots? You’ll find it all at the best UK slot sites.

Table Games

Are you the kind of player that likes to choose a strategy and sticks to an odds chart? Is examining betting options your thing? Then discover multiple variants of blackjack, roulette, baccarat, and craps.

Live Dealer Games

Looking for an authentic experience, where you can speak to the croupier and other online gamblers in real time? Join the action in high definition when having a seat at a live dealer table.

Video Poker

If you like the video element in slots, but enjoy something more strategic like poker, why not try a game of video poker? All its variants feature a simple 5-card draw.

Specialty Games

If you fancy something completely different, like a game of keno or bingo, or even a scratch card or pachinko, head over to the miscellaneous section in the game lobby.
