Real Money Slots App

A perfect example of the technological advancements that have benefited casinos and slots players has been the slots app. Most online casinos now have their own apps that customers can install for free from the app store. Many have now chosen to play slots via an app and prefer this method of play as opposed to browser-based gaming.

There are three very good reasons why slots players should install the app for their chosen casino when playing slots online. The app offers more than just ease of play, it also offers players a better overall experience and in some cases, exclusive bonuses for players.

The first reason to choose a real money slots app is the sheer quality. In most cases, the app sites for each casino are built on newer tech than their online casino sites and are not only visually stunning but run smoother and faster than most browser based slots games via smartphones at traditional online casinos.

Secondly, it is apparent that casino operators are focussing a lot of attention on boosting their slot games selection and this is being reflected in most real money slots apps. This means that more slots games are becoming accessible than ever to casino players who choose to install apps to play slot games online.

Finally, we should also mention that there are many exclusive bonuses offered for customers that install and play via a slots app. If you are looking for a top-quality casino that offers free spins for both new and existing customers then take a look at our best slots sites table, all of the brands listed have their own apps which are free and quick to install.

Best Slots Online – How to claim a Slots Bonus

Claiming an online slots bonus is an easy enough task and one that usually only takes around 30 seconds to complete. Once you have chosen an online casino to play at with the best slots bonus click on “register” or “join now” to begin the sign-up process. Here you will be asked to submit your personal details and to verify your account.

The information that you will be required to input will be pertinent to you, such as; name, address, age, and, username/password. The username can be anything you like (as long as the name hasn’t already been chosen by another customer). Your password will require a combination of letters, numbers and at least one special character.

Most online casino operators employ a two-step verification process for new customers that require email verification once you have registered. This simply means they will email you (usually immediately following the sign-up process) to ask you to confirm your email address by clicking on a verification button.

In some cases, casinos ask for verification via mobile phone. In these instances, they will either text a link for customers to verify or, send a pin-code for you to input at the casino. It is important for both the online casino and the customer that this process is undertaken to such a degree for all-around security and to remain compliant.

You may also be required to upload proof of address in the form of a bank statement or utility bill. This is standard practise online now with KYC (know your customer) protocols in place. You may also be asked to upload a screenshot of your driving license or passport to provide further visual evidence of your submitted details.

Slots Bonuses & Wagering Requirements

Claiming bonuses for slots games is a great way to get more (sometimes a lot more) spins for your money. There are many different types of slots bonuses ranging from free no deposit slots bonuses to standard matched bonus offers that also include free slots spins as part of the overall welcome package.

A standard welcome offer usually consists of a 100% deposit bonus plus a certain amount of free spins added on top. The free slots spins are activated upon first deposit. This type of slots bonus offer is available in over ninety percent of online casinos in the United Kingdom.

A good example of this is Casino Planet. This is one of the best slots sites listed and is currently offering a welcome package of a 100% Deposit Bonus plus 200 free spins. This is a superb welcome bonus from an online casino that is proving itself to be one of the most popular for online slots fans in particular.

We always recommend that our readers spend some time studying the t&c’s for each online casino bonus before registering. In most cases, the slots bonuses on offer will come with some wagering requirements. This means there will be certain playthrough requirements to contend with before any winnings become available to withdraw.

A wagering requirement is basically a multiplier that indicates the number of times you have to play through a bonus before you can make any withdrawals. In the meantime, any potential winnings will remain in the “pending balance” until all wagering requirements attributed to the bonus have been fulfilled by the player.
