Online Slots Guide for Players

Online slots are the most widespread kind of game at first-class online casinos.  They are available in the free-play mode and for real money. Slots for fun allow you to practise playing before you invest in your hobby. It is also an educated decision to polish your skills before trying the real thing. Then you can move on to real money slots, deposit for real, and consequently win real cash.

Playing free slots does not require any registration at an online gambling venue, but it is not financially rewarding either. To start playing for and winning real cash, you need to create an online casino account. On BestCasinos.com you can find a simple step-by-step guide on how to sign up at an online casino. To put it briefly, you need a good Wi-Fi connection, your personal details, e-mail address and a couple of minutes, and that’s it.

Furthermore, some online casinos are instant play, which means you can start playing right away. Open your preferred browser on desktop, mobile or a tablet and kick it off immediately. The other kind requires a software download to play most popular slot games online. Make your choice and you’ll be good to go.

Alternatively, simply play the best online slots here on Best Casinos for as long as you would like. Practice makes perfect, and it takes time to be confident with your slot skills. Every casino gaming software provider nowadays creates games available in both modes. Use our filters to find your dream game. They are sorted based on genres, developers, number of reels and paylines, and so on.

Once you have chosen your favourite online casino, selecting the right slot(s) will be a piece of cake. The key lies in the fact that you do not have to choose one; you can try them all. However, you do need to set aside quite a chunk of time. At the moment, there are probably around 10,000 slot machines in the virtual world.

Important Things to Know When Playing Slots Online

Online slots are divided into two main categories – classic slots and video slots. The former sort is created to resemble the traditional slot machine found at land-based casinos. They feature fruits, sevens and golden bars as their hottest symbols. On the other hand, modern video slots are more encompassing in terms of themes and genres. They come in diverse shapes and forms, such as fantasy masterpieces, horror shows, sci-fi releases or even branded games. Leading game-producing figures like Microgaming and NetEnt are responsible for most of these trademark launches. Check them out here on BestCasinos, read their reviews and play them for free.

Once the aesthetic aspect is out of the way, there are but a few essential things of technical nature you need to know before deciding what game to play. Here is what you need to take into consideration upon decision-making:

  • Device CompatibilityHTML5 is an important acronym in iGaming. If next to the game title you have the short buzzword that means that you can play the slot on varying devices, from desktop, over tablet, to mobile. Covering various platforms is an aim for every modern online casino supplier. Look for the little mark and you’ll know you can enjoy the good-looking slot on your smartphone, iPad and iPhone.
  • Download vs. Instant Play – Depending on who and how manufactured the slot, it will be playable in a different way. Like casinos, slots can be download or instant play. There isn’t any difference in the very game; it is just the manner of accessing it that’s different. Some online gaming brands demand that you download software to enjoy the game lobby, others do not.
  • Payout Percentage – Delving into more technical and mechanic-oriented functionalities, we need to pay attention to numbers. The Return to Player value often referred to as the game’s RTP is the built-in estimation every casino game possesses. It is a calculated figure that concerns the amount of money that will be paid back to players over time. The higher the RTP, the bigger the chance of winning. To date, it is NetEnt that scored the highest RTP – 99% – with its Mega Joker slot.
  • Classic Slots vs. Multiline Slots – As we teased a few lines above, slots vary in physical characteristics. One of them is the number of reels. Classic slots – typically created by renowned, veteran brands – boast 3 reels and 1 payline. In this way, they are made to resemble land-based slot machines. On the other hand, among the most popular slot games online you will often find the 5×3 formed online slots with a bigger number of paylines going from as low as 3 up to around 50, or betting ways. The latter usually offers 243 or 1024 ways, but this is not exclusive. Those square-shaped grids can offer 81 ways. There is no rule to this; it is the manufacturer who decides. In either case, the number of lines/ways determines the number of ways you can make a winning combination.
  • Progressive Slots – Adrenaline addicts and those of you with nerves of steel, welcome on board. Progressive slots give you the greatest chance to win big and boost your bankroll. Virtually every slot provider has in its arsenal a good array of progressive games. Progressive multiline slots are characterised by jackpots that rise with every new bet placed on the game. Ultimately, one lucky player takes it all. For that reason, you should play progressives sparingly; as you can very easily lose every single penny you had placed. Some of the most popular jackpots with players are Mega Moolah by Microgaming and Divine Fortune from NetEnt.

Picking the Right Slots Casino & Bonus

If slots are your favourite casino game, you will not be disappointed with the selection on the market. Slots enthusiasts have the biggest directory of choice of all casino fans. There are multiple thousands of titles in the industry, and they keep coming every single day. Slot developers know what their clients want, and they produce accordingly. Henceforth, here are a few pointers for slots fans for the right slots casinos:

  • Game Selection – With multiple dozens of slot manufacturers on the world’s regulated markets, it is both hard and easy to choose the right one. Therefore, why would you settle for just one? We suggest that you should have a handful of preferred slot creators, and then play a bit of their old goodies, and a bit of their new stuff. Having displayed crucial aspects, we now leave it up to you to see what matters to you most. Is it the looks, the mechanics or something entirely different? At the end of the day, you make the final decision, and no decision you make can be wrong. You are welcome to explore and experiment to your heart’s desire.
  • Free Spins & Special Features – One of the most important factors for the designers is to feature free spins and bonus rounds in their releases. They do this to attract more players. The logic behind it is simple. Why would a player settle for a too simple a slot with the base game only, when they can enjoy a whole lot of gratis turns and extra games? In these rounds, you get to benefit from stuff for free, and everyone loves that! Likewise, the bonus rounds add to the overall excitement and anticipation, and they give you a bigger shot to your wallet!
  • Bonus Offers – Just as free spins are crucial for creators, bonus offers matter to players. Bonus offers come in different shapes and sizes. This largely depends on the online casino you focus on. Therefore, your bonus parcel can be a bunch of free spins, a matched 100% or 200% bonus. They can be even a cash reward granted to you before you even start playing. However, unlike the RTP, more is not always good. If a slots bonus is bigger, it does not mean it will be the best. You should understand the importance of the Terms & Conditions. Read them through before you heedlessly run head-first towards that bonus. There may be unwanted wagering requirements that you may not be willing to meet, or cannot afford. This does not have to be the case, but it is better to stay on the safe side and know the rules before you break them.
