What You Need to Know About Online Slots

Online slots use random number generators (RNG) to determine the symbols that appear on the reels. The RNG is a piece of software that selects a random number every millisecond. When a player presses spin, the maths module in the game translates that number into a result.

While there was a chance to trick the slot machines in the past, it’s impossible now. This means that winning at online slots is purely down to luck.


In a slot game, symbols are the elements that create a winning combination and award players with a prize. These can be in the form of a cash payout or bonus round. They can vary between games, but most online slots use standard reel symbols, wild symbols and scatters.

There are also special symbols that increase your chances of forming winning lines. These include expanding, sticky and stacked wilds. They are usually designed to fit a particular theme and can offer a boosted payout. Some wilds also function as multipliers, doubling the value of any winning combinations they join. These are more valuable than regular wilds, but they don’t pay out on their own.


Paylines in online slot games can make a big difference in your chances of winning. However, you should always check the game’s pay table before playing to see how many paylines are available and their payouts. The more paylines you include in your spins, the higher your chance of winning.

Typically, paylines in slots run parallel to each other and can only be won if matching symbols appear on the same line. However, some newer video slots offer both ways to win and will pay out when symbols appear in adjacent positions on consecutive reels.

Unlike traditional fruit machines, which have a single payline on a three-row, five-reel grid, modern online slots can feature 243 possible paylines. X-Ways slots, for example, allow players to form combinations by landing the same symbol on multiple reels.

Bonus rounds

Bonus rounds in online slot games are a great way to boost your winning chances without eating into your actual bankroll. They’re usually triggered randomly and can take the form of free respins, extra reels, or extra symbols. They can also be a fun way to try out new slots!

Many people have superstitions about slot games, believing that certain days of the week or months are luckier than others. Unfortunately, this is a misconception that can easily cost players money. Instead of betting more money in the hope that the next spin will be a big winner, players should set a budget before playing and stick to it. This will keep them from overspending and potentially ruining their gaming experience.

Mobile compatibility

Online slot games are popular because they are simple and easy to learn. Some offer bonus features like Wilds and Scatters that can help players complete lines to win big prizes. These games are also ideal for mobile gaming because they can be played on a variety of devices and are compatible with most internet browsers.

Many online casinos offer a mobile version of their website or apps that can be used on iOS and Android smartphones and tablets. They usually have a wider selection of casino games than their desktop counterparts and are more convenient to use on the go.

Mobile compatibility also allows users to access their account and personal information at any time. However, it is important to check whether an online casino has a good reputation and adheres to responsible gambling practices.


The RTP of a slot game is the percentage that it is expected to return to players on average over millions of spins. This number does not guarantee wins and cannot be used to predict the results of any individual spin. It is also important to understand that RTP does not factor in the volatility of a slot game.

Understanding RTP can help you make more informed decisions when choosing which slots to play. This can save you money in the long run and help you achieve a more balanced bankroll. Fortunately, this information is readily available online and only takes seconds or minutes to find out. In fact, it is a requirement that any casino offering a game display its RTP and house edge in some way.
