Video slots are the most played online slot machines.

The Progressive Jackpot Network system also includes video slots, scratch cards, table games and live casinos with live dealer games and some poker sites.

There is no way of predicting when the jackpot will drop as it is completely randomised, regulated casinos have no control on when and who wins the jackpot.

It is very important to set a gambling budget and stick to it before you start playing these slots for real money, as the excitement of potentially winning the jackpot might distract you from how much you are spending.

Online Slot Bonuses

All slots bonuses featured on our website are coming from 100% safe and secure, tested, reviewed and ranked online casinos that you can trust. 

At CasinoTopsOnline, we have made it easy for you to choose from a wide variety of slots bonuses, including classic deposit match bonuses, free casino spins, free casino money, free play bonuses, wagering bonuses and special package promotions. Casino promotions and welcome bonuses come in many forms and online casinos which are focused heavily on online slots make sure to design their welcome bonuses around them.

The type and generosity of the welcome offer will depend entirely on the size of the online casino, how long it’s been operating and what it can afford. There is no such thing as ‘free spins’. Free spins will have to be purchased by the online casino offering the promotion, which is why they come with wagering requirements to ensure the welcome bonus won’t be an issue if players are on a hot streak. 


Some casinos craft welcome bonuses which have the best of both worlds, with the aim of satisfying the different types of casino players. But the slot focused casinos will design offers based solely on online slots and give players a selection of slots to choose from. In this section, we’ll be delving into all the different casino promotions which are targeted to online slot enthusiasts:

  • Free Spins Bonuses;
  • No Deposit Free Spins;
  • Welcome Spins.


    As the name suggests, these types of promotions are catered for online slot lovers who play nothing else when at an online casino. The number of free spins awarded in the welcome bonus tends to be far higher than if combined with a deposit bonus and the free spins are usually able to be played on one particular slot.

    The casino will specify which online slot is eligible for their promotion and in some cases, you’ll have the liberty to choose from a number of top online slots. Be sure to visit the terms and conditions first, as from there you’ll discover the wagering requirements and any capped winnings from your free spins. 

    Many casino operators who work with leading game providers usually strike special deals and in turn, will be able to offer free spins bonuses to their players. For instance, many casinos work with NetEnt, the biggest gaming provider in the online casino world and as a result, any free spins acquired will be passed on to new players through free spins bonuses. The casino bonus is a way for players to explore the games of the gaming provider and get a better understanding of player favourites and other important data. 



    No deposit bonuses are hands down the most sought after bonuses by casino players, for obvious reasons. The online casino bonus rewards players just for opening an account as a token of appreciation for choosing them. 

    No deposit free spins are probably the most preferred casino promotions relating to online slot enthusiasts. Players feel at ease knowing the fact that they're able to spin the reels without having to commit any funds. This approach is used because it works. Players are more inclined to deposit funds after receiving a no deposit bonus. 

    As touched upon briefly above, free spins are purchased by the online casino and when offering no deposit free spins, the amount of free spins awarded is going to be far less and usually comes with a capped winnings. It would be catastrophic for an online casino if a huge number of players won big amounts from their free spins, which is why casinos opt for having capped winnings.

    All you need to do to qualify for a no deposit free spins bonus is register with the online casino as a new player and you instantly be rewarded with your free spins. The terms and conditions will list the online slot games available to use the free spins on, so be sure to read through them before you click on 'claim bonus' to avoid disappointment.  


    As explained above, free spins cost money to online casinos and the game selection to use these free spins on will usually depend on the operators main game provider. For instance, some online casinos offer free spins on all NetEnt games in their free spins package while others will only have a couple of games to choose from. Some of the more common games making their way in free spins bonuses include; ‘Starburst, Blood Suckers, Dead or Alive and Rich Wilde and The Book of The Dead. ’ 

    Welcome spins are a perfect way for newbie players to get used to the mechanics of an online slot and an opportunity to get familiar with pay-tables, game symbols and pay-lines. This will make playing slots online a much better experience for any new players! 

    When deciding on the best place to play online slots, it’s worth considering the credibility of the online casino as well as the online casino games to play, the games’ features and casino softwares. CasinoTopsOnline recommends the best online slot sites to play that are 100% safe and secure, tested, reviewed and ranked. Please play responsibly and enjoy your games!
