The Basics of Online Slot

Online slot is a fun and easy casino game that offers a wide variety of themes. Unlike traditional slot machines, online slots don’t require spectators to watch players play.

But understanding how they work is still a mystery for many players. This article will demystify the world of online slots and answer some common questions.

Random number generator

A random number generator (RNG) is the brain of online slot machines. It generates random numbers every millisecond, determining whether or not a symbol will land on a reel. It’s also used for other types of casino games, including keno and video poker. RNGs are unbiased and completely fair, so you can’t influence the outcome of any spin.

The random number generator is an important part of online slot games, and understanding it can help you make better gambling decisions. It’s also worth remembering that online casinos are regulated and regularly audited, so you can rest assured that the games are truly fair. Moreover, focusing on good bankroll management can help you avoid believing in myths about manipulation and predictions. This can prevent you from losing more than you should.


In online slot games, symbols can have a variety of functions. Some offer payouts, while others trigger bonus rounds. In general, there are three different types of symbols: standard, wilds, and scatters. Standard symbols are usually card-based icons that pay out a certain amount of money when they appear in a row on an active payline. The higher the number of standard symbols in a winning line, the bigger the payout.

Some of the most popular online slots also feature special symbols that offer additional payouts or trigger bonus rounds. These symbols can be anything from the Liberty Bell or the horseshoe to a stacked wild symbol, which can fill an entire reel and double the chances of creating a winning line. In addition, some online slots feature sticky symbols that remain fixed for several spins.


Paylines are a crucial part of online slot games, and the number of paylines can be a huge factor in how many wins you make. They can be visualised as actual lines running across the game reels, or they can take a more creative shape, such as zig-zags. Winning payouts require a combination of symbols to land on a payline, and each payline offers a different chance to win.

Traditionally, winning combinations on activated paylines occur from left to right. However, innovative designers have come up with new mechanisms that allow players to form combinations in multiple directions. These include cluster pays, an all ways payline, and a pay both way system like the one used by Pragmatic Play’s Sweet Bonanza. All of these features can add up to significant payouts.

Bonus rounds

Online slot games with bonus rounds add an extra layer of excitement to the gameplay experience. These unique features offer players a chance to win special rewards, including free spins, jackpots, multipliers, and pick-and-win games. Understanding how these features work is essential to maximizing their potential.

Some bonus rounds can be triggered by hitting specific symbols in the pay lines. Others can be purchased for an additional cost, increasing the winning potential of a game. Some of these bonus rounds include expanding wilds, which grow to cover a proportion of the reels or rows, and multipliers that increase payouts. These features can make the difference between a losing and winning slot game. However, it is important to set a winning limit and play responsibly.


RTP is an important statistic to look at when comparing online slot games. It tells players how much of their money should be returned to them over time. It is not a guarantee of winning though, as luck is always a big factor.

RTP doesn’t tell players how often they should expect to win, but it does help them make smarter gambling decisions. It’s also possible to use other stats, such as hit frequency and volatility, to assess a game.

A higher RTP doesn’t mean the game is better, but it does indicate a lower house edge. Whether you prefer high-RTP slots or mega-ways, there’s something to suit every taste. Take the Lewis Carroll/Alice In Wonderland-inspired Alice & The Lost Secrets Megaways by Push Gaming for example, which features five extending reels and up to 248,832 ways to win per spin.
