The above sites are our top picks for an instant play casino UK.

You need to create an account first as all UK casinos need to verify their players before they can play. But the sites above will try to do this automatically based on the information you provide in the sign-up form. If they are successful then this would mean that you are playing at an online casino without verification documents being required. So you can play their slots and games instantly.

NOTE: Automatic approval of a new account is not guaranteed. You may be asked to complete online casino verification UK procedures by sending identification documents to confirm your account, which may cause a delay.

Instant play no deposit bonus codes

The sites above also offer instant play no deposit bonus codes. This means you can sign up – using a code if needed – and you’ll receive a no deposit bonus which you can use to try out the casino’s slots and games instantly. In some cases, you might not even need a code.

The no deposit bonus you get will be in the form of free spins on slots or online casino free credit for multiple games. However, you may need to verify your UK mobile to benefit from an instant play no deposit bonus code. That’s because it’s becoming popular for casinos to offer a no deposit bonus on phone verification UK. After you’ve signed up, you simply need to verify your number using a code sent to you via text.

No download casino

Pretty much every single online site today is a no download casino. Back before fast internet, it was a lot more beneficial to download an app. But these days you can play within your device’s web browser – on desktop and mobile devices.

All sites listed on our UK online casinos list require no download to play. You just need to sign up for a new account to get access to the slots and games. Some sites do offer an app, usually on mobile. However, there is no need to download a casino app from any of the sites listed on Casino Professor – as we make sure they are all available via web browser.

Online casino no deposit bonus no download instant play

The no deposit bonuses above require no download for instant play either. That’s because all casino bonuses are available in web browsers too.

You just need to make sure you trigger the bonus correctly – by entering a bonus code, depositing enough money, activating an offer within a specific timeframe, or something similar. You can check the requirements in the bonus terms and conditions.

Flash casino

A Flash casino UK is getting rarer and rarer these days. Not because you can no longer play casinos online (you can still do this easily) but because the Flash technology is fast being replaced. This is happening because Flash does not work very well on mobile. And since more players are starting to play using smartphones and tablets, something new had to be created.

So all new slots and casino games are now being developed using the latest technology – such as HTML5. This means that the games will be available on mobile as well as desktop. Many older games that were previously developed using Flash are also being updated. However, there’s still a few games that use Flash. You will only be able to play them using a desktop or laptop, and you might have to manually approve the use of Flash (as most modern browsers don’t run it by default).
