What Are Online Slots?

Online slots are games of chance that use Random Number Generators to determine whether you will win. They are also increasingly complex, as developers explore new themes and features.

But what makes these games so fun? In this article, we’ll take a closer look at how online slots work.

Random number generator

Online slot games use Random Number Generators (RNG) to create random results. This technology is a mathematical module that generates random numbers every millisecond. It then connects them to different outcomes on the reels. The number generated at the moment you press ’spin’ will determine the outcome. This is why it’s important to check whether an online casino’s RNG software is certified by a reputable agency like Gaming Labs.

There are some misconceptions about how slots work, including that machines take into account the amount you’ve won or lost. This isn’t true, and gambling regulators always test slots’ RNGs to ensure that they’re fair. However, the maths behind slots do have some ’temperaments’. This means that certain types of games are more likely to have higher wins and less frequent losses.


When you spin the reels on an online slot machine, you’re essentially betting money on a series of random numbers. This determines whether you win or lose, but you can’t predict when it will happen. If you stop the reels, that won’t change the outcome – the result was already decided when you started the spin.

However, stopping the reels will speed up the animation a bit, so you’ll know what the results are faster. But it won’t affect the final result because the same random number would have been used if you had stopped the reels sooner.

Check out the game’s pay tables to see how many symbols you need on a payline to receive a payout. Also, look for scatter symbols, which can trigger bonus rounds and multiply your payouts.


In modern slot games, there are many different types of symbols. Some of them are standard, while others can trigger bonus effects and pay out as well. For example, stacked symbols take up more space on the reels and increase the odds that they will become part of a winning payline.

Normally, winning a payout in a slot game requires a certain number of matching symbols on a particular payline. However, there are exceptions to this rule. For instance, some slots feature stacked Wild symbols that act as a joker and can replace any other symbol.

Other special symbols include Scatter symbols and Bonus game symbols, which do not require a specific position on the reels to produce a win. These symbols are usually linked to the plot of a slot’s storyline and depict key characters.


Paylines are an important aspect of online slot games. Also known as winning lines and betting lines, they determine the number of wins and chances to land a jackpot. While the first slot machines had one payline, modern slots now offer up to 117,649 ways to win!

Typically, online slot paylines run from left to right. However, some also allow players to form chains of matching symbols from both directions. This feature is called ‘win both ways’ and it gives players more options when forming combinations. Compared to traditional fixed paylines, this system is more flexible and has higher payouts. It is also compatible with a variety of bonuses and modifiers, including scatters and wilds. Some of these features can increase your winning potential by triggering bonus games and unlocking extra reels or extra rows.

Bonus rounds

A bonus round is a mini-game within an online slot that can grant you additional winnings. The amount you can win varies depending on the slot, but it usually does not exceed the jackpot prize. Some slots will trigger the bonus round randomly while others let you fill up a meter to initiate the game.

Some bonus games require skill from players while others offer a more arcade-like experience, such as shooting alien spaceships or stealing gems. The number of credits you can win from these games depends on how many triggering symbols you land during the base game. Some slots also come with retriggers that allow you to keep playing the bonus rounds for longer. This increases the overall entertainment factor of the game.
