If you’re into video slots exclusively, the online casino sites we just listed will keep you entertained for hours on end. You will get the deluxe slot machine experience, meeting your criteria in terms of quantity, but in quality as well. Don’t be shy to do some shopping before you seal the deal. If you need extra information on how you can do make a better decision, read on!

What Makes a Great Slot Online Casino?

It takes a trained or better said, an experienced eye to spot the advantages that are of benefit to online slot machine players. Online casinos like to segment the player base so they can provide a better service, or so they say. There are few aspects we pay attention when we prepare our online casino reviews, and they help us identify which player group is at the center of attention.

To make your decision easier, consider the following:

  • Quantity of Slot Games – Plain and simple, the more games are available, the better the chances you will have a better time overall. Out of quantity comes quality.
  • Diversity of Slot Games – It must be pointed out! There are casinos that simply stockpile as many online slot games as possible, yet the best ones, or the most prestigious ones are not available. Quantity is important, but eventually, you will be hooked on a handful of high quality games.
  • Slot Game Filters – Having the largest online slot collection is of no use if there aren’t enough game filters that will make it easy for slot players to navigate the extensive casino game library. In our opinion, without slot game filters, most of the games will never see any attention whatsoever. It’ll be just the games that are promoted by the casino, usually placed in the Popular or New Slots tabs. In simple words, it’s not just the contents of the product, rather how it’s packed and delivered.
  • Slot Bonuses & Promotions – Both slot bonus deals and slot promotions are of great importance. Eventually, you will want to take it to the next level, and maybe take part in a slot tournament, see how you fare against other slot players. Bonus deals, well, we all know why we like them. A batch of free spins, or bonus spins, some extra bonus money, all of them just boost the balance. At the end of the day, the most important thing is to have fun, and actually enjoy slot games.
  • Number of Mobile Slots Available – Overlooked by many, but only a few online casinos boast highly versatile mobile slots collections. Instead of checking it out yourself, you can go through the respective casino review at CasinoDeal.co.uk.

If you go through each of the casinos you think are worthy of your time and money, with the aforementioned criteria in mind, you’ll see that not many can meet your needs.

Casino Bonus Deals at Online Slots Sites

Online casinos look the same, they feel the same, but once we take a look at all features and functions from a bigger perspective, we can easily point out the differences and what makes them special.

Slots online casinos are a special kind, and a few years back, spotting one was rather easy. Besides having the term “SLOT” in the name of the casino, their casino game libraries consisted of slots only.

It goes beyond slot games only, and touches upon the promotions and the bonus deals. Now, as a slot player, you have access to the most diverse promotions, competitions and bonus deals. Below, we’ve listed a few of the most important promotion types from a slot player’s perspective.

Free Spins/ Bonus Spins

Offering 20 free spins up to 50 free spins has become common at well-established online casinos that are operating on a world class level. Top rated slot online casinos take free spins bonus deals to the next level.

Now, when we say free spins, we usually mean bonus spins, which you can get if you make a deposit. With a bonus code or not, a new customer offer or an existing one, slot player oriented online casinos do more, and they usually do better!

In addition, the wagering requirements of free spins or bonus spins deals are usually much more favourable. Now, this is not a guarantee, but it is to be expected. After all, what’s the point of welcoming slot players explicitly, and offering them spins that are subject to high wagering requirements? Believe it or not, this is the case at some slot online casinos that don’t have the player’s best interest on their agenda.

For what it’s worth, one of the benefits of joining an online casino that’s designed with slot players in mind is that you can get free spins and bonus spins on a regular basis. Many players take bonus deals for granted, and once they have to deal with a lack of offers, it’s when they reconsider their decision.

Slot Tournaments

Online slot tournaments are available at online casinos that show great interest in entertaining slot players in particular. You don’t have to be an expert to win a slot tournament. You can take part by playing one or some of the qualifying video slot games. It’s that simple.

Then again, you might want to take a closer look at the tournament terms and conditions, to be precise, take a double look at the minimum qualifying bet size, and what you should be doing to win tournament points.

In general, there are 3 types of online slot tournaments.

  1. Wager the Most Amount of Real Money
  2. Trigger a particular bonus game, or a given event the most amount of times
  3. Have the largest win in a given bonus game

The first type of slot tournaments is almost extinct because it’s against the responsible gambling principles of the UKGC.

Another thing you should pay attention to is whether you can compete in the tournament playing on mobile, because there are certain online casinos that organise exclusive desktop or mobile tournaments.

Giveaways

Now, giveaways and cash drops were rather popular a few years ago. Players were given a chance to win extra prizes, cash, bonus money and various gifts, simply by playing a given slot game. Giveaways are not the same as tournaments, because you’re not competing with other online slot players, it’s more of a game within a game.

Much like slot tournaments, make sure that you clearly understand the requirements. Some casinos might actually require the player to complete a wagering requirement, based on a value estimation of the award granted.

Again, giveaways have become rare, but there still are a few around. You can usually find them at the bottom of promotions pages, under the welcome bonus offer. Nevertheless, some online casinos display this kind of promotions to existing customers.

Online Slot Game Filters and How They Help

Regardless of your play style and what kind of slot machines you prefer playing, slot game filters are absolutely necessary! They become detrimental if the casino game library counts 1,200+ games, and you like to explore new slot games.

Without any game filters, your quest to find a new slot game with, say, free spins might be close to impossible. Instead of accomplishing these seemingly impossible missions, prioritize an online casino that offers a range of slot game filters.

This is basically what sets aside the world-class online casinos that truly value slot players, and are prepared to meet their needs in full! Some of the more useful and popular filters are:

  • Free Spins
  • Bonus Game
  • Multiplier
  • Wild
  • Scatter
  • Avalanche

As you can see, we’re not talking about slot types, such as 3D slots, progressive slots, 5 reel, 3 reel one-armed bandits and so on. These filters, filter out the games based on their gameplay, the game rules and what the rewarding elements are.

Most players have gotten used to using the search box when needed, and playing a few slot games only. However, if you decide it’s time to explore new content, slot filters can be of great help.

No Deposit Bonuses at Slots Casino Sites

Even if you prefer to play with real money only, we think that it’s best if you have a look at some of the best no deposit bonuses at online slot casino sites in the UK. Slot players see a lot of bonus action in the UK, mainly because it’s well regulated, and there are no dirty tricks. If you’re lucky enough, you just might be in time for some free spins with no wagering requirements!

Below, you can find a few casino bonus deals that excel from any perspective, bonus terms, bonus amount and there are no hidden terms that might have an adverse effect on your experience.

Free Slots Online means No Real Money Prizes

You might come across certain sites advertising “free online slots”, but we have some bad news for you. If you’re playing slot machines with “fun credits” or in “fun mode”, you cannot win any real money prizes. Even if you do stumble upon slot sites that do not require real money deposits, yet they promise real money prizes, think again, does it make sense?

The closest form of “Free online slots” are the free spins bonus deals, or bonus spins you get when you sign up at an online casino. This is the only way of playing slots without making a real money deposit, yet having the chance to win such a prize. To make matters worse, even if you do win playing with free spins, you will still have to make a minimum deposit as part of the KYC procedure carried out by all legit UK licensed online casinos.
