SLOTS BONUSES YOU CAN TRUST

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. 

Different types of online slot bonuses

DIFFERENT TYPES OF ONLINE SLOT BONUSES

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.

FREE SPINS BONUSES

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 FREE SPINS

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. 

MOST COMMON WELCOME SPINS

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!

find the best online slot features

BEST ONLINE SLOT FEATURES

These features can be found on most 3-reel classic slots, the ones that resemble the old slot machines you found in your town pub. Particularly popular among the older generation of players. Straightforward and easy to get the hang of, these types of slots never really seem to go out of style.

FRUIT MACHINE SLOT SYMBOLS

A typical characteristic of classic slots. The well-known symbols consisting of cherries, lemons, bells and BAR-symbols, each with their own assigned value from low to high paying. Your bog-standard, run-of-the-mill slot machine.

PROGRESSIVE JACKPOTS

Progressive Jackpots have been around since the brick and mortar casinos, making it a highly volatile yet rewarding feature. By having a bunch of slot machines lined up together, the collective loses will be pooled together into a communal jackpot, making one lucky player very happy once the jackpot it hit! Most online casinos offer progressive jackpot slots.

COINS AND COIN SIZES

An open goal to mention this one in this list, but necessary nonetheless. Coins are used to place your stakes on the slot machine you’re playing on. The coin size determines the value of your stake and how much your wins the payout. The higher the coin size you place on your stake, the higher your payout will be.

VOLATILITY

Not necessarily a slot feature, but more of a mechanic of how the slot machine functions. Volatility is usually stated within the review of the slot game that is currently being played. The higher the volatility, the less the wins the player will land but the higher the payout will be once the player does manage to land a winning combination on the reels. The lower the volatility on a slot, the more frequent the wins are, but the less the player will get paid out.

RETURN TO PLAYER (RTP)

Something that is completely in the hands of the software provider when it develops the game. Like the volatility, the RTP will always be stated before playing the slot game. RTP can range from anywhere between 90% to 98%. The lower the RTP, the higher the volatility on a slot machine is.

PAYLINES ON SLOTS

The word paylines might confuse rookie players at the beginning, but the definition of the word is actually quite straightforward. Paylines simply are the winning combination that can be made on a slot machine, ranging from a humble 20 or 25 to a whopping several thousand depending on which slot you are playing.

All the ways to win in the best slots

WAYS TO WIN IN THE BEST SLOTS

There are several Ways To Win features, one being specific to one game provider. Although they are not very commonly implemented in many slot games, you will find them from time to time.

WIN BOTH WAYS

Like the name suggests: this feature allows the player to strike up matching combinations using both ways on the reels. Whereas normally players are only able to utilise combination made from left to right on the reels, the Win Both Ways features goes both ways, increasing win chances.

243 WAYS TO WIN

The 243 Ways To Win was the first one of the features to be developed and implemented on online slot machines. Like the name gives it away: slot machines with these features allow the player to land a winning combination in up to 243 different ways, increasing chances to win and landing a higher payout as well.

1024 WAYS TO WIN

A massive upgrade from the original 243 Ways To Win feature. 1024 is always played on a slot machine with 5 or more reels, making it possible to combine different symbols into this whopping amount of winning paylines.

MEGAWAYS FEATURE

Perhaps the crème-de-la-crème of the Ways to Win features. This slot technology has been developed by the software provider Tiger Gaming and is one of the biggest trademarks on their online slots. The Megaways feature allows up to several thousand winning paylines.
