Whether you are an avid casino player or have just opened an account at a virtual casino, you may have several questions about playing slots. Although RNG-based virtual slots are inspired by old-school slot machines, they incorporate several elements that deserve special attention.

Even if you are simply spinning a few reels for fun, it is still worth learning about the specifics of virtual slots and how to play them correctly. Depending on your preferences, you may find some slots more attractive than others. Learning about paytables, potential returns, and other slot features will help you make the most of your online spinning adventures.

While slots are luck-based games, knowing which titles offer better odds of favorable outcomes is still beneficial. Proper bankroll management will also play a major role in your online slot sessions. Even if you think you know everything about slots, we recommend reviewing the information we provide – you can always pick up something new that may help you improve your virtual slot play.

Things to Know When Playing Slots

At its core, playing a video or classic slot isn’t rocket science, but inexperienced players often overlook several details before wagering real money. Before you place any bets, it’s always wise to review the game’s payouts, RTP, special features, and symbols.

Understanding every element of a slot will help you decide whether it suits both your preferences and your predetermined budget. Don’t be fooled by a game’s design; in the long run, other factors are far more important.

Checking the Paylines of the Slot

Before playing any game, you should check the slot’s paytable and the paylines that generate payouts. Not all slots award wins in the same way; different variations may offer a different number of paylines.

  • Wins paying from left to right – A payline is a winning combination of identical symbols on adjacent reels that awards a payout when those symbols land on the designated line. Some paylines pay exclusively from left to right, meaning the player will receive a payout only if the winning combination starts on the far-left reel and continues across the adjacent reels to the right.
  • Wins paying both sides – Some slots award payouts for combinations formed in either direction. In these games, the player is paid for a winning line that starts from the leftmost or the rightmost reel.

Paylines vs Wats to Win

While some slots have paylines that award payouts, others have numerous ways to win, with winning combinations being formed in a different manner.

Traditional 3-reel slots have a single payline in the middle of the slot, awarding a win whenever three identical symbols land on that line. With 5-reel slots, there are more lines that can grant a payout when three or more identical symbols are matched. Slots with multiple payline may have 20, 30, or even 50 different lines that pay out for different winning formations across the grid of the slot.

As gaming developers always look for different ways to present a more attractive gameplay, plenty of slots started offering 243 ways to win, 1024 ways to win, or even more. This means that instead of the typical horizontal, vertical, and diagonal lines, these slots have numerous other winning patterns that can grant a win. Instead of granting payouts for combinations on a payline, however, slots with ways to win award payouts for simply matching identical symbols on adjacent reels.


Checking the Paytable of the Slot

As mentioned above, not all slots share the same number of paylines or the same mechanics for landing a win. In addition to reviewing the lines that can generate winning combinations, you should also examine the slot’s paytable.

The paytable lists the different symbol types used in the game, their values, and the minimum number of identical symbols needed for a payout. When you play most 5-reel slots, you typically collect a payout for matching at least three identical symbols on a payline or on adjacent reels. There are, however, slots with higher-paying symbols that can award a win even when only two identical symbols appear.

When studying a paytable, pay attention to how the payouts are expressed. Many slots state that payouts are calculated as bet-per-line wins. This means your total wager is divided evenly across every payline. Some slots even let you choose the number of paylines to wager on. Whenever three or more identical symbols land on an active payline (one you have staked), the figure on the paytable shows how many times your bet per line will be multiplied.

You may also encounter paytables that express payouts in coins rather than multipliers. Regardless of the format, it’s easy to estimate your potential win once you land a winning pattern. Before spinning the reels, review the paytable so you know which combinations promise the most rewarding results.


Slot Symbols

When you open a slot’s paytable, you’ll see every symbol used in the game. Typically, these symbols are split into low-value and high-paying icons, meaning some combinations yield smaller wins than others.

Many slots use playing-card symbols for their low-value icons. These usually range from 9 through Ace, with each symbol offering similar payouts, although the face cards (J, Q, K, and A) may pay slightly more.

For high-paying symbols, most slots choose icons that are thematically related to the game. High-paying icons can deliver larger wins and may even pay out for combinations of only two identical symbols.

Beyond the regular symbols, many slots include special symbols such as Scatters and Wilds. These icons generally have unique functions that can help players rack up bigger wins.

1Wilds

These symbols usually serve to replace other symbols in the game. Thus, when a Wild lands on the reels, it can complete paylines that would otherwise not pay out. Some slots feature different types of Wilds that further expand the capabilities of this special symbol.

2Special Wilds

You may encounter expanding Wilds that can cover entire reels and lead to more winning combinations. Another variation is sticky Wilds, which stay in place for several spins. As a result, they can also help you land multiple wins and enjoy more rewarding outcomes.

3Scatters

These symbols are usually the icons that trigger a slot’s special features. In most cases, a certain number of Scatters must land on the reels to activate a bonus. A single game can include various types of Scatters, each linked to a specific feature.


Bonus Features

As mentioned above, Scatters are usually the symbols that trigger a slot’s special features. Depending on the game, different bonus rounds can activate at random and lead to bigger wins. Before spinning the reels, it’s worth reviewing the features you can unlock.

One of the most common bonus rounds is Free Spins, allowing you to play several spins without wagering additional money. The number of free spins may be fixed, or it may depend on how many Scatters triggered the round.

Free-spin sessions can also include extra perks such as sticky or expanding Wilds, multipliers, or other special symbols. Some slots let you retrigger the free-spin round by landing additional Scatters, while others do not.

Certain games offer a pick-a-prize bonus, awarding instant payouts or boosting wins you’ve already collected. The presentation varies by game, but players are typically given several options to pick from and reveal hidden prizes.

Whatever bonus game you unlock, you can expect entertaining ways to grow your bankroll and chase bigger wins.


Setting Up Bet Size

After reviewing the paylines, symbols, bonus features, and payouts, you’re almost ready to play. Before spinning the reels, however, you need to set your wager. Although this step seems straightforward, many players underestimate how crucial it is to choose a bet that fits their budget over the long run.

You’ll get the most value from your session when you select an appropriate bet size. If you have a predetermined budget, make sure your stake allows you to play for as long as possible. Opt for slots with lower betting limits so you can enjoy more spins and extend the fun.

If you’re on a small budget, there are certain slots you should avoid. Progressive jackpot games may sound alluring, but they often require higher wagers. Needless to say, if you plan to play with limited funds, you won’t last as many spins as you would on a standard slot with a more reasonable betting range.

Once you settle on a comfortable bet size, begin your spinning adventure and fully enjoy the experience.

Other Things to Consider Before Playing Slots

Playing slots is simple, especially once you know what information to check before wagering real money. As noted above, you’ll enjoy a better gaming experience when you compare the paytable, symbols, and special features of different slots and choose the version that suits you best. Beyond these basics, a few additional factors can help you select the optimal game and boost your chances of winning.

By combining your knowledge of symbols, bonus features, and payouts with the elements discussed below, you’ll elevate your gameplay, have more fun, and enjoy greater opportunities for slot wins.

Hit Frequency in Slots

Hit frequency is usually expressed as a percentage and shows how many spins are expected to result in a win. For example, if a slot has 1,000,000 possible outcomes and 200,000 are winning spins, its hit frequency is 20%.

Many new players ignore the percentage of line wins in a slot. Some games include features like stacked Wilds and multipliers that can deliver large payouts, yet they may have a low percentage of line wins in the base game. While these slots provide chances for big rewards, they offer fewer opportunities for smaller, more frequent wins.

Conversely, slots with fewer bonus features often award line wins more regularly. These high-hit-frequency slots are better for players who prefer steady payouts instead of waiting for a single huge win that might drain their budget first.

Remember that hit frequency is unrelated to a game’s RTP. Knowing the hit frequency does not reveal the RTP. Generally, slots with high hit frequency pay smaller amounts, while those with lower hit frequency compensate with higher payouts.

You’ll often encounter low-paying slots that substitute some larger prizes with more frequent small wins at the same hit frequency. Developers can also fine-tune hit frequency by a small margin – something most players will hardly notice.


Slot Volatility

Hit frequency is closely related to slot volatility. In simple terms, a slot with a low hit frequency but larger, less frequent wins is considered highly volatile. Conversely, a game that awards smaller payouts more often is classified as a low-volatility slot with a high hit frequency. When a slot pays bigger prizes less frequently, it falls into the high-volatility, low-hit-frequency category.

Volatility should play a major role in your game selection. Depending on your bankroll, you might favor low-volatility slots over high-volatility ones. High-volatility games carry greater risk, so it’s wise to set a budget and choose slots that match your comfort level.

1When to Play Low-Volatility Slots?

Low-volatility slots are ideal for players with a limited gaming budget. Because these games provide smaller but more frequent payouts, players have a better chance of collecting steady wins instead of waiting for bigger payouts and exhausting their balance. Although big wins may sound enticing, players with smaller bankrolls can quickly run out of funds before reaping even a single small win. If you prefer lower risk or cannot afford to play for an extended period, low-volatility slots are the better choice.

2When to Play High-Volatility Slots?

High-volatility slots are best suited for players who enjoy riskier gameplay. Such games typically offer much larger payouts, but small wins occur less frequently. As a result, it may take quite some time before players see any return. Still, the hefty payouts can compensate for prolonged losing streaks. Generally, those who can afford to wager over an extended period reap the benefits of high-volatility slots. If you are comfortable risking a portion of your bankroll while waiting for a massive win, high-volatility slots might be perfect for you.


Progressive Jackpots

When a slot includes a progressive jackpot, it can change your approach. Although the core rules are similar to standard slots, your betting strategy may differ. Like high-volatility games, progressive slots appeal more to risk-takers.

To qualify for the massive prize, progressive slots often require the maximum bet. Players with smaller budgets might quickly exhaust their funds before they can fully enjoy the game and its features. While progressive jackpots can be large enough to offset extended losing streaks, they occur infrequently, and regular payouts are usually smaller.

If you’re determined to play progressive slots, keep the following tips in mind to maximize your enjoyment:

  • Set your budget before you start playing progressive slots
  • Always place the maximum bet to remain eligible for the progressive jackpot
  • Select games with the largest jackpot prize pools to improve your potential returns
  • Stick to the fixed budget you established for your session
