How Do Online Slots Work

Slot machines are arguably the most popular casino games to play today. There are two important reasons why online slots are everywhere: ease of gameplay and random outcomes. To play, you just set your wager and click ‘Spin’ to land matching symbols. The results of every spin are at random thanks to the use of the Random Number Generator or RNG. It’s a program that randomly creates a string of numbers or symbols that serve as the basis for the game’s results.  This ensures that for every spin of the reels, you get random and fair outcomes.

To fully understand its operations, it’s important to begin with its components. All online slots feature virtual reels that are based on the mechanical reels of slot machines. Depending on the game, you will find three to five reel slots. These virtual reels will display the symbols and if at least three reels show matching items, you collect a payout. Some of the best and modern Twin slots feature five reels and they often pack colorful symbols, engaging themes, and lucrative bonuses.

Betting lines

In online slots, you will find betting lines or winning lines. This simply refers to the combination of symbols that qualify for a payout. For example, in the classic slot machine, there’s one betting line that runs from left to right. Now, if you match all three ‘bell’ symbols in a single line, you win a payout. In modern Twin slots, you will find multiple betting lines. For example, you will find free slots with 10, 20, 40, or even 243 betting lines. You will even find some slot machine titles that offer more than a thousand betting lines, especially for the Megaways brand.


At the heart of the slot machine is its collection of symbols. Symbols are associated with payouts, and you can collect an instant win by matching at least three symbols from left to right. Now, the choice of symbols differs depending on the game or the software provider. Often, the symbols are based on the game’s theme. For example, Vikings-themed free slot games will use Norse-inspired symbols like helmets, the Vikings, and longships. When playing online slots, you’ll also encounter special symbols in the form of wild, scatter, and multipliers which are all explained below.

Types of Online Slots

If you’re a frequent casino player, then you know that most portfolios are dominated by online slots. These casino games are colorful, easy to play, and come in different types.  Some of the most popular types of slot machine are 3-reel slot, 5-reel slot, and progressive jackpot games that are all playable at Twin Casino.

Of these games, the simplest are the 3-reel slot machines or fruit slots. They’re the classic free slot machines that take inspiration from the mechanical slots found in pubs and physical casinos.

Symbols Classification

As mentioned, online slots work and deliver the payouts through their symbols. In real money slots online, you’ll find regular symbols and special symbols. For the regular-paying symbols, these are the items that are related to the game’s theme and offer you payouts depending on the number of symbols present. The actual payout for a specific game is explained in the paytable. And then you’ll find the free slots special symbols which can activate big wins, the bonus rounds, or even the game’s biggest jackpot.

Bonus Symbols

If you’re after big wins, watch for the game’s bonus symbols.  In most slot casino games, these symbols are appropriately labeled which makes it easier to track their appearance. You need these symbols to activate the game’s bonus round. A popular type of bonus to play is the ‘Pick Me’ bonus. In this round, you’re provided with several items and you need to pick a few to reveal the prizes.

Scatter Symbols

For players who love free spins, then the symbol to track is the scatter. As the name suggests, these symbols can appear anywhere and still offer a payout. Aside from coin wins, scatters can help activate popular slots online bonus: the free spins round. In the free spins bonus, you can win extra spins which you can use to play the game risk-free. In most real money slots, you need to land at least three scatters to enter this round.

Wild Symbols

This is another special symbol that’s present in most online slots. As a special symbol, the wild is designed to substitute for other symbols to create more winning combinations. Also, this special symbol will often deliver the game’s biggest payout by landing all five symbols. There are different kinds of wilds with the two popular variants, expanding and stacked, explained below.

Expanding Wilds

Expanding wilds will not just replace game symbols. These will also expand beyond their reel locations to occupy bigger spins. The symbols can expand to the next reel or in some popular online slots, they cover the entire reel. A popular Twin slots game that uses this mechanic is Starburst by Netent. Here. The spinning star acts as the wild and it can expand to cover the whole reel.

Stacked Wilds

Compared to expanding wilds, the stacked symbols will appear on top of each other. These special symbols can deliver big wins and in some cases, may also activate re-spins. To learn more about these symbols and how they work, you can play free slots like Medusa and Space Wars.
