The Basics of Online Slot Machines

Online slot games are fun and easy to play. There’s a whole world of technology working behind the scenes to create an exhilarating experience for players. They’re also a great way to relax and unwind.

Some people believe that slots are rigged, but this is not true. Slots use Random Number Generators and a specific Return to Player ratio to ensure fairness.

Random number generator

Random number generators are used in online slot machines to ensure that each spin is fair. While this does not eliminate the possibility of cheating, it does make the games less predictable than their physical counterparts. In addition, the RNG in online slot machines is a constant; the chance of getting a certain result is the same every time you play.

Besides ensuring a fair game, the RNG also provides quick results. This is important for players who are looking to gamble safely and quickly. However, players should choose reputable casinos that do not tamper with their RNGs. If you’re unsure about whether or not a casino is trustworthy, check its licensing and certifications before making a deposit. Also, make sure to read the Terms and Conditions thoroughly.


Online slot machines use a set of reels to display symbols and determine whether the player has won or lost. The slots can have anywhere from three to five reels and a variety of paylines. Some also have special symbols and bonus features that offer lucrative payouts.

However, despite all the bells and whistles, an online slot game’s outcome is still completely random. The software uses a piece of computer code to generate a series of numbers, which correspond to different symbol combinations. The winning combination of symbols then pays out the prize, which is determined by the game’s paytable. Unlike physical older slot machines, which have mechanical mechanisms to spin the reels, online slots have software-based RNGs to determine the results of each spin.


Paying symbols are a crucial part of online slot games. They determine the winnings hierarchy and add a variety of gameplay features to your experience. They can be standard or bonus and can have many different functions, including wilds, multipliers, re-spins, sticky symbols, etc. The most common symbols are the standard ones, which offer payouts when they appear in a row on an active payline. These include the classic fruit symbols such as cherries, watermelons, lemons and oranges.

Another type of symbol is the wild, which acts as a joker and can replace any other Standard symbol on the reels to increase your chances of making a winning line. There are also walking and expanding wilds, which move one position on each spin or up or down the reels respectively.


Paylines in online slot games are the lines that form a winning combination to reward players with instant payouts. Depending on the game, you can activate up to 20 or 30 paylines per spin. Activating all the paylines increases your chances of winning and is recommended. However, you can also choose to activate only a few of the paylines.

The paylines can be simple and straight or they can take a zig-zag shape across reels. They can be horizontal, vertical or diagonal and they will always pay if 3 symbols match. Usually, the paylines will run from left to right but there are also slots that feature an all-ways-win or cluster pay system that do not care about the direction of the winning combinations.

Bonus features

Whether it’s a simple pick-one-of-three chests game, a complex multilevel videogame-like experience, or a free spins round that doesn’t reduce your bankroll, bonus features can add extra win potential to online slot games. They can also speed up the game’s progression, making it more exciting and engaging. However, they should be handled with care. They can be a costly gambling tool and should only be used by players who have set limits and play responsibly.

Bonus features are triggered by certain symbols in the base game of an online slot machine. They vary from game to game, and you should always read the paytable for details on how to trigger them. Some bonus games may require you to fill up a progress bar, while others have a specific minigame mode, like a spin-the-wheel or a pathway game.
