What Are Online Slot Games?
Slot games are familiar to most people. They can be found at casinos, arcades and even at your local bar. But online variations take the large machines and condense them into digital versions that have far more freedom in how they’re designed.
You can find slots with every theme under the sun, bonus rounds, huge jackpots, and just about anything else you could dream up. Some even have stories that spread across multiple games.
The Basics
Like traditional slot machines, most online casinos have spinning reels with symbols. When they line up over what’s called a payline, you win. You’ll win the value of your bet multiplied by whatever you scored.
However, modern slot games can change this up a bit, with cascading reels that continue to reward you when you hit a payline, and grid slots that harken back to games like Candy Crush or Bejewelled.
The Role of the Random Number Generator (RNG)
You’ll hear the term RNG, or random number generation, thrown around a lot when discussing online casinos. It’s a common term in all digital games, and simply refers to the programs used to create random outcomes.
For online slots, true random generation is what tells you that a game is fair and unrigged. The RNG for online slots is incredibly sophisticated, as it has to account for not just spitting out random numbers, but doing this in accordance with the house edge, or Return to Player, as we call it in slots.
External auditing and gambling licenses are how you can tell if an online casino has fair slots. So always check if you’re concerned.

Types of Slot Games You’ll Find Online
There are many different slots to play at online casinos. Here are some of the main types you’ll encounter.
Classic Slots
The classic type of slot is just an adaptation of the old classic slot machines. You place a bet and spin the reels to see where they land. There aren’t many flashy features, but these offer the pure, old-school slots experience.
Video Slots
It’s only natural for video slot machines to find a place online, where the graphics and interesting bonus rounds can really shine. These slots have all sorts of themes, bonus rounds, jackpots and rewards. This is also where you’ll find the most experimentation with features.
Progressive Jackpot Slots
A type of slot pioneered by industry titan Microgaming, these slots have a side jackpot that accumulates as all players bet on the game. A little of every bet is added to the jackpot, which you then have a shot at winning. These games have lower RTP ratings, but that’s the trade-off for a chance at a huge jackpot.
RTP and Volatility Explained
As briefly mentioned, RTP or return to player, is how we refer to the house edge when talking about slots. It’s the average amount of money bet on the game that is eventually returned to the players (hence the name).
Volatility is the frequency and value of those winnings. A high volatility game will pay out less frequently, but in much larger amounts. The opposite is true for low volatility games.
If you’re looking for excitement, high volatility games are your best bet, but for consistent returns, we recommend low volatility, high RTP games.
Tips for Playing Online Slots Responsibly
Online slots are one of the easiest games to sink a lot of time and money into without thinking about it. So it’s vital you understand how to gamble responsibly and maintain healthy habits while playing.
Set a Budget and Stick to Limits
No matter what you’re playing, you should always set a budget for the play session. And we know it’s easier said than done, but you must then stick to that budget. Deposit limits at online casinos can help you do this.
Play for Fun, Not for Profit
Greg can make casino gaming seem fun and profitable, but you must never play to win. Instead, play to have fun. Always be willing to lose money, and don’t set out to make any. This mindset will also make it easier to step away when your budget runs out.
Safer Gambling
Slots are one of the easiest games to get carried away with. This is why it’s so important to gamble responsibly and make full use of the tools available at our top casinos to keep your habits in check. You can set deposit limits, time-outs and even full self-exclusion if things go too far.
