Best Online Slots in 2024

Among all gambling diversity, slots stand out due to their widespreadness, variety, lucrative bonus features, and hugely massive prizes possible to get, especially when it comes to gambles with progressive jackpots. It's the answer to why video slots are at every online casino, making up the majority of available online gambling diversions. 


But that's where the problem streams since such a gamble's variety makes it much more challenging to pick the best online slots. Therefore, you need to know some crucial things that let you pick the game that best suits you. But first, let's become more familiar with the main types of slots.

Types of online slots

The best online slot games may be classified by so many parameters — theme, reels' quantity, bonus functions, special symbols, used mechanics, etc. But the simplest way to divide them into distinct kinds depends on which type of jackpot is used — fixed or progressive. Also, there is quite a grave difference between those old-good classic slots and modern video games, visible even to the naked eye. Therefore, we will describe the brightest specialties of these widespread slot types.

Classics slots

Among the popular slot games are well enough those already got the status of true classics. Often, these are the precise copies of real-life slots from land-based casinos. Usually, they have three reels and just several pay lines. Many have enjoyed playing these through the decades. Classic slots have simple rules, and none of those complex mechanics or bonus features just let you collect three in-row symbols to get a win. Some such slots even propose to double the prize using a gamble round. 


Therefore, many have been tired of modern video slots overwhelmed with bonus features, like time-to-time back to the 3-reels and so simple classic slots, to indulge in sweet nostalgia. The most popular titles among these are HOT 777 Delux, Monkey Madness, and Lucky 7.

Video slots

These are modern gambles, which drastically differ from those classic ones by a diversified number of reels, various special symbols (Scatter, Wild, Walking Wild, Shifting Wild, etc.), many lucrative mechanics (Book, MegaWays, Avalanche, etc.), and engaging bonus games of so many different kinds (free spins, respins, Hold'n Win, etc).


Among such online slots best have beneficial bonus functions, which include FS, respins, multipliers, and a range of special symbols. Many players take advantage of this modern video slot specialty, hunting for the most prospective bonus rounds since their triggering mostly lets gamblers make it to the plus side, earning some extra dozens or even hundreds of euros over their balance amount. Among the best modern games beloved by many are Sweet Bonanza, Gates of Olympus, and Gladiatoro.

Progressive slots

Among the best slot games to play, some are with fixed jackpots, while the others — progressively growing with each stake. Despite it being much easier to get the fixed prize, many like to play slots with continually increasing jackpot prizes since they may reach unbelievably big, up to millions of euros. Thus, it is a way to become the owner of the massive money prize in just one click. Yet, it's not that easy to get it awarded. Some of the most desirable progressive jackpots have triggered just one time per several million spins. Therefore, your chances to get such a jackpot aren't that high. Yet, if you like to dream about someday becoming a millionaire, that's what you need. The most famous slots of such kind are Mega Moolah, Jackpot Giant, and Major Millions.

Popular online slots

As you already saw, there is a vastness of slot machines diversified as a lot of things to differentiate them — by features, mechanics, jackpots, etc. For instance, there are many of the best slot games with such an incredible mechanic as Megaways. Let's learn why that feature is so popular.

Megaways Slots

Each slot awards cash prizes according to the pay lines due to the pay table. Thus, when the paying symbols of a single kind land on one of them, a corresponding reward is granted. While classic games usually have just several win lines, most modern gambles deliver many more, up to several dozen and even hundreds. 


Moreover, those video slots with MegaWays mechanics may propose dozens of thousands of pay lines. And that seriously increases the possibility of wins, especially when this mechanic is combined with some other — for example, with Avalanche mechanics. Bonanza Falls, Sweet Candy Cash Megaways, and Buffalo Mania Megaways are the best casino slot machines to play with this lucrative feature involved.

Jackpot Slots

Huge wins are the best opportunity to get to the plus side when playing some slot. Therefore, the best casino to play slots necessarily proposes games with big fixed or another type of jackpot — local, network, or progressive. Despite the last ones being the most known for their big prizes, fixed rewards at some slots can reach dozens of thousands to the stake. That's a pretty influential reason to play such games.

New Online Slots

Each of the best casinos for online slots takes care of providing its players' access to not only classic or time-tested gambles but also the newest video slots from the most esteemed developers. That guarantees all those online gambling venues' visitors the broad list of diversity diversions they could take advantage of. 


This approach makes it impossible to get bored, regularly giving a chance to check the generosity of new prospective video slot titles. Moreover, it's a great opportunity to get familiar with new bonus features and gameplay mechanics. Among the most popular recently released games are Lucky Otter, Galactic Racers Dream Drop, and Pine of Plinko 2.

How to play online slots

Many slot sites grant an opportunity to play for money or for free. The last variant is possible due to the demo mode, whereas to play for money, you have to be a registered user of some online casino. After authorization in your account, you need to take these several steps to get involved in playing on real money:
