Different Types of Online Slot

There are many different types of online slot. Each one has a different format, genre and gameplay experience. They also have their own payouts and rules. These differences can be confusing to new players.

Fortunately, there are ways to understand these machines better. You can start by examining the basics of how they work under the hood.

Bonus features

Online slots have many different bonus features that can add an extra element of fun to the game. These can include free spins, scatter symbols, and even progressive jackpots. Some of these features may require you to hit a certain combination of symbols to trigger them. Others might have you complete a minigame to unlock a prize.

Wild symbols are a classic feature that can be found in most online slot games. These symbols substitute for any other symbol on a payline to create a winning line. They also increase payouts by allowing players to match high-value symbols. These features can add a lot of excitement to the game, but it is important to remember that they should not interfere with responsible gaming practices.


The reels in an online slot machine are responsible for spinning the symbols and awarding payouts. These symbols can be anything from standard slot icons to bonus symbols that trigger different features. They can also be stacked to increase the number of potential winning combinations.

While the physical layout of a reel limits the number of blank spots and symbol positions, software designers created virtual reels to mimic their functions. These virtual reels have the same blank and symbol positions as the actual reels, but they are spread out across multiple rows to allow more than one symbol to appear on each position.

Various combinations of symbols on the reels can unlock bonus games that award cash, points or free spins. Bonus rounds can be as simple as an instant cash win or as complex as a skill game.


Symbols are the basic building blocks of any slot game. They have no special functions other than to form patterns on the paylines and award a payout when enough appear in a row. The size of the payout depends on the number and value of the symbols involved in the combination. Standard symbols usually include bells, dollar signs, BARS, and lucky 7s, though some games feature symbols that are unique to the game’s theme.

Another common type of slot symbol is the scatter. These often trigger a bonus event and can offer high payouts. Scatters can also be used to unlock free spins rounds and other features, such as 243 ways or Megaways, which increase the number of potential winning combinations.


Paylines are one of the most important aspects of online slot games. They determine how many matching symbols can form a winning combination, which ultimately leads to a payout. They can run horizontally, vertically, diagonally, or zigzag across the reels. Depending on the game, they can also be fixed or variable.

Traditional slot machines used to have one payline that awarded players a payout when three or more matching symbols appeared on the same row. However, as technology advanced, more multi-line slots began to appear. Today, players can choose from a variety of online slots that offer up to 25 or more paylines. Some of them even use X-Ways, which allows symbols to match anywhere on the screen without needing to land along a payline.


While jackpots are not the end-all of online slot games, they add a certain appeal to these machines. They function like the financial crescendo in a symphony, collecting a percentage of every bet and adding it to the overall prize pool until one player hits the jackpot.

These prizes can be huge and often top the millions of dollars. However, they also lower the machine’s return percentage, as a portion of each bet is diverted to increase the jackpot size. This can be a significant drawback, particularly for players on tight budgets. That’s why it’s important to find a machine that offers a moderate number of payouts and has a low minimum bet.
