Understanding how slots work goes beyond reels and paylines—players are more likely to engage when they perceive a game as fair and easy to use. The general rule of thumb for how online slots work is as follows:
Select your chosen slot game. Make sure you check the game information so you know useful information such as payline structure and return to player (RTP).
Enter your wager using the bet selector, and configure any additional settings such as audio.
Click the spin button. The reels will then spin and stop at random. Many slots have unique payout structures, but in your standard video slot, you’ll find that winning combinations are made for landing three or more matching symbols across an active payline. Special symbols such as scatters and wilds can trigger bonus features or assist in payouts.
Any winning combination will be highlighted and all payouts are made per the paytable. When the player is ready they can click the spin button to spin the reels again.
The online slots world is so extensive, that it can be a bit overwhelming to know where to start. Luckily there is a selection of staple slot series that online slots fans have loved for years. Trying out these top titles can be a great place to embark upon your online slot journey.

As mentioned, slots can come in so many different forms and themes, but there are a few features of online slots that are often universal.
Free spins bonus rounds are a staple of online slots, and it’s often considered to be outside the norm if a slot omits one. Most commonly triggered by landing three or more scatters, free spin quantities can range wildly, with some slots offering around 6-10 at a low end, and others offering up to 50. Some slots allow free spins to be retriggered, and some free spins games will have modifiers such as the sticky wilds mentioned earlier.
The gamble feature is commonly seen in older or retro-inspired online slots. This is an entirely optional feature which players can choose to activate when they win. Players can use this feature to get a chance of increasing their win. Most commonly this is done by guessing the colour of a face-down playing card or with a ladder which players can scale, or drop down on.
Scatter symbols in online slots can form winning combinations when two or more of them land on the reels in a single spin in any position. Some scatter symbols take the form of bonus symbols, and typically three or more of them will grant access to a bonus feature such as free spins. Some scatters have a paytable value of their own, while others do not.
A respin is a single additional spin of the reels. In some online slots, this may occur to give players a second chance to form a winning combination and pins certain symbols in place while the rest spin. Other respins are seen in bonus features, with a countdown of respins on offer that get reset if the player can land more winning symbols.
Wild symbols are special symbols that can substitute for all other non-special symbols to form a winning combination. In some online slots, the wild symbol is the most valuable in the game. Wild symbols may also be subject to modifiers, such as ‘sticky wilds’ which stick in place for a set number of spins.
Here are just a few reasons why our players love playing online slots at Prime Casino:
Many online casinos solely focus on gaining new players with welcome offers, but we want all our players to feel valued. Because of this, you’ll find lots of fun promotions taking place on our site throughout the year. Some are seasonally themed, some celebrate a specific online slot or developer, and some are offered by SkillOnNet to players across the platform.
With so many developers, the online slot world moves fast. Because of this, if you are a big slots fan, you’ll want to never miss out on a new release. At Prime Casino we add tons of new slots to our site every month, so there’s no chance you’ll feel behind the curve.
Prime Casino is part of the SkillOnNet Network. Being affiliated in this way benefits our players because it means we get to be part of network-wide early access offers where players can enjoy highly anticipated online slots weeks before their global release.
Although recent research suggests that more experienced players tend to return to slot games they’re familiar with rather than choosing at random, here are some practical tips if you’re just getting started.
Slot volatility is the measure of the frequency of wins and average win amounts on a given slot machine. A slot machine with low volatility will often pay out modest wins in quick succession, while a machine with high volatility will usually pay out large prizes spaced apart over numerous spins. Different levels of volatility are designed to appeal to different types of players, so consider this before you play your chosen online slot.
We advocate for responsible gambling, so when you play online slots, be sure to set yourself a budget and play limit, and stick to it. Pay attention to your mood when playing, if you’re getting frustrated, take a step back. If you’re on a losing streak, never chase losses, instead, step away.
Every online slot on our site will include game information. This information will provide details such as the game's theme, payline structure, bonus features, and more. Knowing this information can assist you in choosing the perfect online slot for you.
All casino games including online slots have a return to player percentage (RTP). This number represents the statistical value of funds a player will receive back when playing. The average RTP of online slots is 96%, and slots with statistics below this may be better avoided.
Our online slot games can be enjoyed in free-play mode. This gives you the chance to test out the game and learn its features before wagering real money. This way you can decide if you like the game risk-free and can avoid expensive learning curves.
