What is an Online Slot?

Online slot games are played on a series of vertical reels filled with symbols. These are spun and stopped randomly by a Random Number Generator (RNG) that is independently audited to maintain fairness and prevent rigging.

There are some misconceptions about how online slots work. For example, some people believe that there are certain times of the day or month when slots are hot or cold. This is untrue.


In an online slot, there are many different types of symbols that can appear on the reels. Typically, they are used to form winning combinations and trigger bonus games, free spins, or other rewards. These symbols are usually designed to match the game’s theme and can vary from one game to another. Some examples include Dropping Symbols, Cascading Symbols, Avalanches, and Tumbling Reels.

The least valuable paying symbols are standard reel symbols, which are often a combination of card suits (Hearts, Diamonds, Clubs) or the classic fruit and slot machine icons. They offer a small payout when they land in consecutive positions on an active payline.

The next level up are the high-paying symbols, which match the theme of the slot and can pay a larger amount when they form a winning line. They are often animated and represent the main characters or objects of a theme. Other special symbols, such as Wild Multipliers, are also found in some games and can multiply a player’s wins.


Paylines in online slot games are set patterns that run across the reels and can host winning combinations of matching symbols. Some slot machines have fixed paylines while others allow players to adjust the number of paylines they want to activate with each spin. The more paylines you activate, the higher your chances of winning, but the more your total bet will cost. Some slot games also offer “pay both ways” options, which means that any symbol can appear on any payline and still award a payout.

Most online slot games come with a paytable that displays the paylines and their payouts. These are typically located in the corner of the game window and can be accessed by clicking on an ‘i’ or a question mark icon. The paytable will also reveal the RTP rate, which is a key factor when determining your chances of winning. However, the RTP varies between different slots games.

Bonus rounds

A bonus round is a mini-game within an online slot that offers additional chances to win money. It can be a simple pick-me-up game where players choose symbols to reveal coin prizes or a multiplier, or it can be a multilevel videogame-style experience that lets gamblers shoot aliens or other creatures. The mini-games in online slots are a fun and exciting way to increase the amount of winnings.

While bonus rounds are often based on luck, they can also give players the opportunity to make large payouts. They can be triggered by scatter or wild symbols and can be re-triggered during free spins. They can also be paid for with the player’s credit balance. They can also include features such as extra Wild symbols and win multipliers. Regardless of their nature, bonus rounds are an excellent addition to any online slot. They can add a sense of excitement to the gameplay and make the experience more engaging for gamers.


In the world of online slot games, RTP is a statistic that represents the average percentage of all bets that will be paid out to players. This figure is based on a theoretical calculation and it does not account for individual spins, but only the overall performance of the game over many thousands of plays. This is important to understand, because it can help you manage your bankroll more effectively.

Another important stat is hit frequency, which indicates how often a slot is likely to pay out. This number can range from one in ten to fifty per cent, but it does not necessarily mean that a high hit frequency means you’ll win more money.

RTP in online slots is a critical concept to grasp because it reflects the performance of a casino game over time. However, it’s also important to remember that each spin is independent of the previous one. This is because a random number generator (RNG) produces a series of numbers that lack any pattern, making each result completely unique.
