Online Slot Machines – The Basics

Slot games were some of the first casino games to come online, with pioneering firms like Microgaming and Playtech creating some of the earliest titles.

Things have come a long way since then, and the new slot games coming out today can come close to resembling video games. Some have as many as 10 extra features and bonus round, and some blockbuster slots even have infamous movie scenes woven into them.

If you are new to slots, there are a couple of important terms to understand. Either memorize these, or even better bookmark this page, so you can come back and look at it again if need until you are familiar with how slots work.

Here are some key slots terms. Understanding these is key to understand how to play slots.


Both bets and jackpots are denominated in coins in the world of online slots. Think of coins as tokens. They have a cash value, which you can often control by manipulating the game settings.


The jackpot is the maximum payout for that particular game, Each game has high-value and low-value symbols. They key to triggering the jackpot in most instances is to get 5 of the highest value symbol on a payline.


These are simple the patterns which lead to wins. Long gone are the days when you had to match 5 symbols straight across. Most slots offer at least 10 paylines, with some offering as many as 100 or more. The more ways to win, the more frequently you will score cash, but the more it will cost you to play.


Each game has a certain number of reels, which symbols spin on. The most common number by far is 5 reels. The majority of online slots follow this format.


Each game has its own symbols related to the theme. For example, if the game is football themed you might see symbols like footballs, boots, trophies, and nets on the reels. The key to winning is to get matching numbers of these along active paylines.

How to Play Online Slots

How toAll slots follow a pretty simple structure, even though the games themselves can be quite different.

This quick 4-step guide will cover you for most slot games:

1 – Check out the paytable.

This can be a sub-menu on the screen, or can be obviously signposted. This will tell you everything you need to know about the game such as the paylines and features. Check it out if you want to understand the game before you play.

2 – Pick the number of active paylines you want to play.

You won’t be able to do this on every game as it is sometimes fixed. It is always better to play the maximum number of lines to maximize your chances of winning. Note, however, that the more active lines you play, the more expensive it will be.

3 – Set the coin value per spin.

Remember we mentioned coins earlier? These are the currency of online slots, and you will need to set the coin value up front. This will determine the total bet amount. It will be the amount you bet per payline. You can always double check the total amount, which will be shown somewhere on the game screen, before you spin.

4 – Click spin and get going.

Once you have completed the previous steps, it’s showtime. Keep in mind that you will be betting for real money. Wins and losses will be affecting your balance from this point forward.
