A Guide to Online Slots at JacksPay Casino 

Video slots and progressives are undoubtedly the most popular games in casino history. And here at JacksPay online casino, things are no different. 

There’s a reason that most online casinos stock hundreds (if not thousands) of slots in their libraries: they give players the perfect combination of excitement, variation, playability, and payouts. But don’t worry if you’re not a slots expert just yet, Jack is here to walk you through it all:

So without losing any more time, let’s dive right into it. 

The Different Types of Online Slots

Online slots have come a long way from the pull-lever, 3-symbols-along-the-middle machines you used to find in bars and casinos. There are now several unique variations, each with their own benefits and appeal. 

Video slots

The majority of video slots have 5 reels, 15-25 symbols, and around 20 paylines (see the Terminology section to learn what a payline is). Players spin the reels and try to land symbol combinations to trigger payouts: rarer symbols means higher payouts. 

But that’s only scratching the surface. Video slots also offer unique in-game special features and bonuses. Characters come to life and swap symbols, groups of matching symbols can transform or disappear, and endless animations can take over the screen. 

Players can spend endless hours lost in just one video slot. When you throw in the potentially massive payouts from higher-variance games, profits can also soar during this time. 

Top benefit: entertainment. 

3-reel classic slots

Classic 3-reel slots are designed to mimic the original physical slot machines. Players typically win by lining up 3 matching symbols across the middle row, with 7s (or triple 7s) paying the most. The old-school designs and gameplay are aimed at older players. 

These games offer lower excitement and substantially smaller payouts compared to video slots, but the retro designs and simple mechanics still attract a large group of players. 

Top benefit: nostalgia. 

3D slots

These are video slots which are specifically designed to look more 3D and immersive than normal games. There is often a storytelling element to 3D slots, often with characters moving around on-screen. In terms of game mechanics and payouts, these operate entirely like normal video slots. 

Top benefit: immersive gameplay. 

Progressive slots

So far we’ve talked a lot about gameplay and visual design - but what about money? In progressive slots, a small percentage of every wager is fed into a collective jackpot. As long as players keep wagering, this jackpot continuously (progressively) grows in size. 

Progressive slots jackpots can be triggered on any spin, by any player. With one-off payouts reaching hundreds of thousands (if not millions) of dollars for $1 wagers, it’s not hard to see the attraction of progressive slots. 

Top benefit: massive payouts

Demo games

For new players, the unusual mechanics and bonuses can make slots hard to figure out. While learning to play, it’s therefore hard to maximise success and new players often end up draining their wallets. 

Demo games are simply free versions of normal slot games. The mechanics, RNG, and payouts are identical - the only difference is that you’re wagering free, virtual currency. Demo slots are a must for new players since they give you time to fully learn the games before committing your cash. 

Top benefit: zero risk.

Online Slots Core Terminology  

As we’ve said, online slots can be a little overwhelming for new players. Here’s some core terminology to help you ease into playing with minimal confusion.


The vertical spinning elements of the slot, where all the symbols are stacked. 


Most slots have hidden routes from left to right across the reels. Matching symbols need to land on these ‘routes’ (the paylines) to form valid winning combinations. 


A special symbol that only appears on some reels. Scatters usually trigger bonus rounds and special one-off payouts, even when they don’t fall on a payline. 


Another special symbol, wilds can substitute for any other regular symbol to complete a winning combination. In some games, wilds can expand or multiply to make even bigger wins. 


An in-game feature which increases the size of payouts. For example, a 3x multiplier would turn a $50 win into a $150! 


Every winning symbol combination pays a specific amount. Players can read the paytable (via ‘settings’) to see exactly how much each different symbol pays out. Payouts are always relative to the wager amount. 


Constantly hitting ‘spin’ can get repetitive or feel slow. Most games have an autospin feature which plays for you, as quickly as possible. This can be stopped manually at any time, or via an automatic loss or win limit. 

Bonus Features and Spins 

Most video slots today have built-in special features which, in addition to making gameplay more exciting, also provide massively increased payouts. For most players, accessing bonus rounds is their main goal when playing video slots. 

Bet Size

All online slot games have a minimum and maximum bet that you can wager per spin.

RTP (Return to Player)

This is the average expected financial return for each game. For example, for a game with a 97% RTP, players should expect to lose roughly $3 from every $100 wagered. 

This is an average, however, so of course some players will lose or win more than this. 

Volatility (Variance)

A low variance game pays out often but small. The majority of players look for high variance games: payouts are far less frequent but considerably higher value. Anyone looking for a life-changing payout should play high-variance games. 

What Makes a Top Quality Video Slot? 

Here at JacksPay online casino we only stock the highest quality video slots. But there are thousands of bad slots out there, too. So what’s the difference between an average video slot and an excellent one? 

  • The developer - The world’s best casinos use the world’s best game developers. These are the companies that consistently deliver on graphics and animation quality, storytelling, bonus features, and payouts. JacksPay slots are all designed by first-rate developers. 

  • Bonus rounds and special features - It’s not enough to have a good payout. Players need to see innovation and creativity: what does this new slot offer that the old favourites doesn’t? Top games create immersive experiences that players haven’t seen before. 

  • Payout size - Self-explanatory. Players want to see big payouts, and they want to see them often. 

  • RTP and volatility - High RTP means players will, on average, be able to maintain their bankroll for longer periods of time. A good RTP would be 95% or higher. An equally crucial payout metric is volatility. Regular payouts are worthless if the amounts are tiny; this is what we would call a low volatility game. Games with high-volatility pay out far less regularly, but for significantly bigger sums. 

Online Slots Bonuses and Promotions

The vast majority of online casino bonuses are targeted at slots players. Let’s take a look at the 3 most popular types of promotion. 

Matched deposit

Here at JacksPay, new players can trigger a 400% deposit match up to $400. This is one of the best bonuses in the entire online casino industry - but what does it mean?

  • If you deposit $20, you’ll receive an extra $60 bonus cash in your wallet. 

  • If you deposit $100, you’ll be playing with $400. 

All that bonus cash is on the house.
