Casino slot machines have been the most popular sources of entertainment in the gambling industry for decades and they remain a fundamental part of internet casinos too, usually taking up a big chunk of the game libraries and catching the most attention with both beginner and experienced players.

Some of the best casino slot machines in Las Vegas have been adapted to the online environment and while most of the casino-goers know how they work, we now take a step back to cover the basics – including salient features much needed to learn how to pick the best suit according to preferences.

What to Know About Slot Machines

  • Slot machine games take up almost 90% of casino capacity, both land-based and online
  • It’s important to be able to distinguish good slots from the rest
  • We now cover the most important features of any slot machine

Important Features of Online Slot Machines

Slot machines create a game of chance and usually feature between three and five reels in three or more rows, where players spin the reels in search of winning paylines pre-set by the providers and bet certain parts of their bankroll. For simplicity, winning potential, and the thrills gambling is known for, casino slot machines top the lists of preferences for many casino aficionados and this has enabled a smooth transition to the online environment too.

Themes & Design

Casino online slots have always been a great place for an inspired approach to themes, as providers go a long way to create appealing machines that will entertain the end-users. This has led to the fact it’s now hard to imagine a topic or theme which is not turned into a slot, which makes choosing an enjoyable app very important.

This is especially true regarding overall graphics, animation, and symbol design, which now always play a great role with the new members. An enjoyable experience that is fun, safe, and glitch-free is an absolute must nowadays.

RTP & Volatility

Furthermore, it’s important to know the winning possibility and probability, where an RTP serves as proof as to how much the machine will return to the player in the long run. While this is not necessarily meant for a short session one might play with the Free money offered by crypto offshore casinos, long-term objectives should be subjected to a realistic and high RTP.

However, game volatility is just as important when rating a slot machine, as it actually determines the nature of the game and the types of winnings it offers. For example, highly volatile slot machine casino online will offer higher payouts but with the cost of them coming less frequently, while low volatility means a great chance at smaller winnings bagged more often. Check out our "Is FanDuel legit?" to see their reliability when it comes to slots.


Paytables offer insight on how the specific slot machine works, also including the special features and the casino slot machines jackpots. It’s important to study the paytable and see what paylines are in play, which is usually developed in a similar fashion for a number of slots by a single provider. Paytable will also show the potential payouts for all options, from higher-paying to the lowest paying symbols and rated by a number of them in a winning line.

Understanding the paytable is crucial for understanding the basics of a slot machine and it can be found in the help menu with every single slot out there. This is best to be done in practice, as seeing the reels spin and rake in winnings goes a long way.

Stakes & Winnings

Moving through the Help menu, players are also able to learn about the minimum and maximum stakes – which are just as important for the overall gameplay. Some casino slot machines and games are tailor-made for high stakes players, while others allow lower coin values and consequently lower bets as they attempt to better suit beginners and slower burning through the bankroll. These limitations will also manifest in potential winnings, which can again be found in the paytable with a need to multiply the number of coins with the coin value to get the real money wins.

Managing the Bankroll

Online gambling is a high-risk business and it’s important to play only with what one can afford to lose. This means that depositing more than you’re willing to play for in never a good idea, even if it means capitalizing on the full bonus offer by the casino. Bankroll management goes hand in hand with the stakes players want to play, where smaller bankrolls demand lower bets made for a single spin, and high-rollers can’t really enjoy the luxury to play the same sort of bets as building on big funds in such a manner can be excruciating.

Usability & Availability

Casino slot machine apps need to be simple and straightforward, featuring controls over coin size, paylines (if applicable), other settings, and help in prominent places on the screen. User-friendliness is a major point with great software providers and this is bound to catch one’s eye almost immediately after making the first couple of spins.

Of course, it’s also important for the slot to be available across platforms one might want to use now or in the future. Many of the popular casino slot machines online have dedicated apps to desktop users as well as mobile enthusiasts regardless of their preferences – including Android and iOS phones and tablets. Take a look at our PokerStars casino review and Borgata casino review to see what these top providers have to offer.


Most of the software providers or casinos players set up accounts with will allow players to try the Demo version of the slot before investing real money, in order to see the major features in action and get a better feel of the functionality. This is a great way for the novice players to learn the ropes but also allows devoted players to see the paylines working out and actually see if the given machine ticks all their boxes. While casinos usually offer a limited amount of free casino slot coins in demo versions, these tend to be just enough to grasp what’s it all about.

Casino Offers

Software providers partner up with casinos to offer games and this usually results in many of the great casino slot machines available on legal and fully safe sites. However, before setting up an account with any casino for a single slot machine, players are encouraged to take an in-depth investigation on all the features available. This includes taking a look at licenses, security, banking methods, customer care, promotions, casino bonuses, and even other games in store – as everyone enjoys alternatives from time to time and it’s important to have a big collection at one’s fingertips.

Finding more than one of your favorite games, whether it’s slots, table games, or video poker is certainly possible, as most of the prominent websites offer libraries including hundreds of games. Slot machines will also take a big part of that number, which gives slot lovers even more choice at hand.

Great US casinos will also offer welcome packs to new players, which include Free money bonuses just for registering an account and this allows players to effortlessly check through everything they might be interested in, even spinning the reels a couple of times with no pressure of investing real money. Once players do choose to move their bankroll, prominent casinos also offer sizeable deposit bonuses which can be used as a great boost to it but hold strings attached – meaning the player has to wager the bonus amounts a certain number of times before being able to withdraw any funds from the account. All this makes the choice of a casino possibly the most important task when searching for new machines to play on.
