Finding the Best Online Slots Bonuses

How do you find the best online casino for slot bonuses? More importantly ones which suit your gaming requirements. It can be a tough task these days with so many online casino sites to choose from. Online casino sites offer different welcome offers and ongoing promotions. So, how do you find the best casino for you? 

With a seamlessly endless amount of online casinos, finding the best sites and promotions can be difficult. Here we will go over some of the main features of online casino welcome bonuses and no deposit offers, how to find the best sites with top features and bonuses on the market. 

100% matched bonus on first deposit to use on online slots

The 100% match deposit bonus for online slots is one of the most common promotion used in the online gaming community. Online casinos will offer a generous matched deposit bonus of up to £100 when new customers sign up and make their first deposit. Meaning you will receive a £1 bonus for every £1 deposited to use on slot games.

  • Deposit £20 into your account and receive a £20 bonus fund balance, you will have a playing balance of £40 to play with.
  • Deposit £100 into your account and receive a £100 bonus fund balance, you will have a playing balance of £200 to play with.

It’s essential to review the terms and conditions, including any wagering requirements, to make the most of this exciting promotional offer.

Welcome Bonus Offers for online slots

Possibly the most common and appealing of these promotions are Casino welcome bonus offers, which are available at almost all online casino sites and are also known as first deposit bonus or signup bonus. 

Each casino site will have their own offers which can range from 100% matched deposit offers to 300% welcome bonus on your first deposit to that casino.

In addition to welcome bonuses, some sites offer second deposit, third deposit or multiple ongoing weekly deposit bonuses. 

More examples of casino welcome bonuses for slots:

Free Spin Bonus 💎

While the matched deposit bonus funds may be for some players, other players prefer their welcome bonus in free spins. Many casinos will give the option to choose which welcome bonus you would like to receive, so the choice is up to you.

Examples:

  • 100 free spins on Book of Dead when you sign up and deposit £10
  • 50 free spins on selected slots when funding your account with £5
  • 100 free spins on Book of Dead no deposit required
  • 10 no wager free spins when signing up for an account
How Do Free Spin Bonuses Work?

Once you have signed up to the casino offering one of the above mentioned promotions and make your first deposit. You will then be awarded free spins to play with before using your cash balance.

The winnings receive from these free spins will be awarded as a bonus balance. This can be appealing to players, as the bonus balance at the end of the free spin session could be larger than the amount received from a matched deposit bonus. Of course, this can work both ways and could end up a lower bonus balance than taking a 100% matched deposit bonus. 

No Deposit Bonus Offers for Online Slots 💷

What are No Deposit Casino Offers?

As the title suggests, these offers do not require a payment upon joining. These offers are usually in the form of a cash bonus for free or free free spins. These offers can be useful to test the sites slot games and features. 

Simply sign up to the site and receive the offer. Whether a cash bonus to play on any slots of your choice or in free spins on a selected slot from that casino, make the most of these offers to test the casino first hand without spending your own money. 

Some examples of these offers can be:

  • Sign up and receive £10 in free bonus funds.
  • Sign up today and receive a free £5 cash bonus.
  • Sign up and receive 50 free spins on selected popular slot games.

It is worth noting that these signup bonuses may come with wagering requirements before a withdrawal can be made from your account. Always make sure you check the terms and conditions on the casino site you are joining.

No Wagering Free Spins Bonus

What are no wagering free spin bonuses?

A casino may offer a welcome sign up bonus where you can make a deposit and in return, receive free spins where the winnings are converted straight to a cash balance with no wagering! 

This is a great type of bonus to take advantage of. You are not being tied into certain wagering restrictions and wagering requirements. You are also not restricted to playing certain slot providers or keeping your stakes below a set value. 

Can You Withdraw a Bonus Balance?

When it comes to withdrawing cash to your bank from a casino bonus, a common question which is asked is how to withdraw the funds? This is dependent on the casinos terms and wagering requirements associated with the bonus. 

Typically, most online casinos will implement wagering requirements with a players bonus balance. This will involve betting the bonus funds a certain amount of times before the balance is converted to cash. Once these requirements have been met, you can make a withdrawal from your total balance straight to your chosen payment method. 

It is crucial to alway check the wagering and withdrawal terms before committing to a casino bonus to ensure a pleasant gaming experience and cash out process. 

What is RTP in Online Gambling and Slots?

What is RTP in online gambling and how can this have an effect on wagering? A question which is asked a lot around the online gambling industry and relevant to slots as well as live casino games. 

RTP is an abbreviation of “Return To Player” simply meaning, this is the calculated amount which is returned to the players in winning results from wagers.

You will find RTP displayed as a percentage and is typically between 80% and 99%. This figure is calculated over an enormous amount of computer generated completed rounds. Each slot game will have been tested for this figure and will be shown in the information pages of the game menu.

In simple terms, the higher the RTP percentage the more of the wagered funds across the game rounds is paid back in wins. Slots with high RTP will tend to pay more of wagered funds back to the players and more often. 

It’s important to note that is this over all players and not just one session for any one player. If the game displays an RTP of 95%, it doesn’t necessarily mean you will get back 95% of your wagered amount back. Ultimately, it’s all down to luck. 

Is It Good to Play High RTP Slots?

It’s always a good idea to keep RTP in mind when trying to fulfil wagering requirements of a slots bonus. Playing slot games which have a higher RTP can help reach wagering requirements without losing your balance.  

Responsible gambling

In order to stay in control when playing at online casinos, providers offer tools which you can use to help manage your gaming experience. 

Deposit limits

Deposit limits are a tool to help limit deposits over a set time frame and can be useful to not chase money after a losing session. These limits can be set daily, weekly or monthly. 

Casino Loss Limits

Casino loss limits can be set at a certain cash value. This can be helpful when you decide to continue gaming but are only willing to lose a percentage of your balance.

If you have a balance of £500 but are only willing to lose £100 of the balance, set a loss limit of £100 and once your balance hits £400 the loss limit will stop game play for the set timeframe. This ensures that you can take a break with a satisfactory balance and not chase any losses.
