Slots are the most popular game genre in both land-based and online casinos. Slots have a long way of evolution from heavy, metal machines in casino venues to sophisticated software on online gambling platforms. Modern online slots offer a wide selection of games based on their feature set, integrated jackpots, and mechanics.
For example, you can launch the Crosstown Chicken slot game demo mode and watch a chicken cross the road with every other spin. Or you can benefit from the Avalanche mechanics playing Gods of Olympus and increase your chances of winning with every other spin. However, the basic concepts that underlie slot games are almost the same, and below you can learn more about them.
The Basics of Online Slot Mechanics
The first thing you see when launching the slot game is symbols that form reels and rows. This is the basic concept that is common for both slot machines in real casinos and online gambling sites. As for the latter, reels and rows may be designed in different ways, vary in numbers, and more. Software developers try to create games so they can comply with modern trends and target the widest audience possible.

Reels form vertical columns and spin every time you click the start (or similar) button. After the reels stop spinning, they form paylines, which may differ from game to game. For example, if you play Pirots 3 by ELK Studios, the game offers 6 reels and 7 rows, while 777 Golden Hit by BF Games has a 3×3 layout. As for paylines, their number may vary depending on the layout as well as mechanics. For example, there are games with fixed paylines as well as those where they may vary. This is seen in slots with cascading reels and avalanche mechanics.
Symbols
Symbols appear on reels and are combined in specific patterns. Many different symbols may trigger a bonus round, bring extra FS, increase the winning sum, and more. Below, you can check out more info about the main types of symbols to get a big picture.
| Symbol type | Description |
| Standard symbols | The most common type in any slot game without specific features. There may be icons with Diamonds, Cards, Bells, Golden Bars, and more. Players receive winnings when they match in specific combinations. |
| Wilds | Wilds replace other symbols to increase the chances of winning combinations. They act as jokers in card games. When playing, you can experience three main variations of this symbol: sticky, expanded, and stacked. |
| Scatters | These symbols may appear at any time on any part of the playing field. They trigger different bonus rounds as well as free spins. |
| Bonus symbols | These symbols play the same role as Scatters but must be collected in a specific combination. |
| Multipliers | After landing these symbols, they can increase the winning amount by a specific coefficient, such as x2, x5, etc. |
How Online Slots Work
Even though slot games are different, they work similarly. At the basis of every slot lies a Random Number Generator that determines the round outcome. To get started, a player chooses the betting sum and starts spinning the reel to activate the whole process. Below, you can check out more on RNG as well as the betting and spinning aspects.
Random Number Generator
Random Number Generator (RNGs) is the main technology that is responsible for slot fairness and unpredictability. At its core, this is an algorithm that creates random sequences of numbers that cause the round result. Currentдy, there are two types of RNG available: Pseudo-Random Number Generators (PRNGs) and True Random Number Generators (TRNGs).
The first one uses mathematical formulas to generate numbers that appear random. This is the most popular and widely used RNG in online slots. The second one is extremely rare in casino games, as it uses physical phenomena (for example, atmospheric noise) for true randomness. Here is how the RNG works:
1. Continuous number generation. The RNG creates thousands of numbers per second, even when you do not spin the reels. Every number is related to a particular symbol on the reels.
2. Triggering a spin. After the player hits the “Spin” button, the RNG uses the latest number in its sequence. Next, numbers map to a specific arrangement of symbols according to the paytable. Slot players can always check the paytable in the info section. 3. Getting a result. A player gets a win or loses the round and repeats the process.
When playing certified slots, gamblers are guaranteed transparency, no human intervention, and complete independence (no “hot” or “cold” streaks).
Main Concepts Of RTP And Variance
When describing slots, providers always highlight their RTP and volatility. These are the main factors that impact the gambling experience and potential winnings.
What Is Return To Player?
RTP is the percentage of the betting sum a gambler can return after multiple playing sessions. For example, if a slot has an RTP of 97%, this means players can get 97 USD on every 100 USD placed. However, the full cycle may require a lot of spins you need to make.
Understanding of Volatility
Volatility is another important feature that explains the frequency and size of wins. If a player picks a slot with low volatility, they can expect to get small winnings, but more often. If a slot has a high variance, then cash prizes appear rare; however, their sizes are significant. Thus, the first option may be a choice for newcomers or cautious players, while the second type is a pick for high rollers.
