What You Need to Know About Online Slot Machines

Online slot games are a lot of fun. They usually have high payout percentages and offer a variety of bonuses. You can also enjoy multiple paylines and cascading reels.

Some players believe that they can ‘beat the system’ by playing slots. This is simply a superstition. The maths behind a slot machine will always win out over time.

Random number generator

Random number generators (RNGs) are the backbone of online slot machines. These electronic microchips generate thousands of different number combinations every millisecond. As soon as a player presses the spin button, the RNG translates these numbers into symbols that appear on the reels. These symbols can award payouts based on their rarity.

The RNG also ensures that the results of an online slot game are fair and unbiased. Despite this, players should be aware of common myths about manipulation and predictability in slot games.

The machine’s RNG doesn’t know whether you’re spinning manually or using auto-spin. It’s also not aware of how much you’ve won or lost in the past. This is because the randomness of the game is a function of time, not the player’s actions.


Unlike their mechanical counterparts, online slot machines use virtual reels to spin and award payouts. These digital reels are programmed to show different combinations of symbols every time they spin, making them more interesting and challenging to win. This also allows for a wider range of paylines than traditional slot games.

Oftentimes, players confuse rows and paylines when playing online slots. Rows are strictly horizontal straight lines of paying symbols, while paylines can be either straight or curved lines that the slot’s developers have come up with.

Nevertheless, the number of rows and reels has no effect on RTP, Volatility or Winning hit frequency. This is contrary to what many shady websites may suggest. This means that it is important to set a bankroll before you start playing and stick to it.


While the exact results of a slot game are determined by a random number generator, symbols can offer players a visual interpretation of those results. They also help to make the game more entertaining. Standard slots symbols typically offer payouts when they appear on winning lines, while special symbols such as Scatter and Bonus symbols can trigger exciting free spin rounds or award higher payouts.

In addition to the basic standard symbols, online slot games often feature unique speciality symbols that can maximise your chances of winning. These can include Expanding Wilds that expand to fill multiple reel positions, Shifting Wilds that move about the reels, and Stacked Wilds that appear in stacks more than one position high. These symbols can add significant value to your wins, particularly in slot games with a large pay-table.


The paylines of an online slot machine determine whether you win or lose a game. This is because symbols must land on a winning line to trigger a payout. The paylines of an online slot are set by the software developer during development, so they remain consistent regardless of where you play the game.

There are many types of paylines in online slots. Some are vertical, diagonal, or zigzagging. Others are fixed and can only be activated with a specific number of coins per spin. The amount of paylines in an online slot can vary widely, from a single line to hundreds or even thousands of paylines.

Most modern slots feature multiple paylines. Most of them arrange them in the standard left to right format, but some also offer a “pay both ways” option that rewards symbols from both the left and right sides.

Bonus rounds

Bonus rounds are a popular feature that can be added to online slot games. They are usually triggered with Scatter symbols and Wild symbols and can win players extra credits and free spins. Some bonus rounds require skill while others are simply chance-based. These added features are designed to increase the game’s winning potential and add a level of interaction and excitement.

While these bonus rounds can help you increase your chances of winning, it is important to remember that they are not guaranteed. This is why it is important to play responsibly and set a win limit for yourself. Also, be sure to check the payout table before playing to make sure you’re getting the most bang for your buck. This way you’ll know whether or not the slot machine is worth your time.
