We look at the features of classic online slots, including symbols, structure, RTP, and volatility. Plus how they work through the use of random number generators, betting mechanics, paytables, and winning combinations.
What are Classic Slots?
Classic slots refer to the traditional, simple slot machines that were the predecessors of modern casino gaming. These classic games, sometimes called “fruit machines” or “one-armed bandits,” usually have three reels and a limited number of paylines, typically only one. The symbols used in classic slots are usually basic and include fruits, BARs, bells, and sevens. These machines were the basis for the modern slots that we see today, which have expanded the number of reels, symbols, and paylines.
Classic slots follow simple rules and gameplay mechanics that are suitable for beginners. You place a bet, spin the reels, and wait for a winning line of symbols.
Features of Classic Online Slots
Classic Slot Symbols
- Bar Symbols: The bar symbol dates back to early slot machines and is typically represented by the word “BAR” written on a simple rectangle or square icon. Bar symbols can appear as single, double, and triple bars, with higher values attached to the higher bars. The origins of bar symbol come from the machines used to dispense gum from the Bell-Fruit Gum Company. Instead of using poker cards as symbols, they had pictures of gum bars on the reels.
- Sevens: The lucky number seven has been a popular symbol in slot machines since their inception. Sevens are typically styled in a bold font, and the color red is the most common hue associated with this iconic symbol.
- Fruits: Fruit symbols had their origins in the early days of slot machines when the machines dispensed chewing gum with fruit flavors. Fruits like cherries, plums, lemons, oranges, and watermelons have been featured on classic slot machines for decades. The cherry is typically the lowest-paying symbol.
- Bells: Another iconic symbol of traditional slot machines, owing its origin to the first-ever slot machine called the Liberty Bell. In classic online slots, the bell symbol often represents a medium to high-paying icon.
Classic Slot Structure and Gameplay
Some key features that identify a classic slot include:
- Single Payline: Classic slots usually come with a single payline, which runs horizontally across the center of the three reels. Wins are achieved by lining up identical symbols on this payline.
- 3-Reel Slots: Another notable feature of classic slots is the presence of three reels, a format that dates back to the earliest slot machines. With three reels in a classic slot, the game grid is typically 3×3, meaning that there are nine symbols presented on the screen at a time.
- Fixed Jackpots: Classic online slots generally offer fixed jackpots, which means that the top prize remains constant regardless of the number of times it is won or the amount of money wagered on the game.
RTP and Volatility
- RTP: The Return to Player percentage refers to the amount of money that a slot game is programmed to give back as winnings to the players over a long period. In classic slots, the RTP often ranges from the low to mid-90s..
- Volatility: Classic slots tend to have low to medium volatility, which means that they offer more frequent but smaller wins. Low-volatility games can provide longer gaming sessions and consistent payouts, while medium-volatility games can offer a balance between frequent smaller wins and the chance of hitting a more significant payout occasionally. High volatility slots, on the other hand, lead to infrequent but potentially massive wins.
How Do Classic Online Slots Work?
Classic online slot games use a Random Number Generator (RNG) to decide the outcome of each spin. When a player spins the reels, the RNG produces a random sequence of numbers which then corresponds to symbols on the reels, ensuring a fair and random result.
RNG (Random Number Generator)
An RNG is a software algorithm that makes sure each spin is entirely random and unpredictable. The RNG generates thousands of random numbers per second, and when players hit the spin button, the most recent random number determines the outcome of the spin.
The use of RNG ensures that each spin is independent of previous or future spins and is based solely on chance. This guarantees that the game is fair and players have equal opportunities to win, regardless of how the game has behaved in the past.
Spin Mechanics
Once the bet is in, the player spins the reels by pressing the “spin” button. The reels will then rapidly spin and come to a stop, to show a combination of symbols. If these symbols match the ones specified in the paytable, then the player will receive a payout.
Autoplay features are also available in many classic online slots, allowing players to set the number of spins and watch the game automatically play several spins without any further player input.
Paytables and Winning Combinations
Paytables display the winning combinations of symbols against their corresponding payouts. These tables clearly show you how much you can win on each combination of symbols..
Payline in Classic Slots
In most cases, classic slots feature only one pay line, which typically runs horizontally across the middle of the reels. When determining whether a spin results in a win or not, the pay line is the reference line that is used to evaluate the combination of symbols.
In some cases, classic online slots may feature more than one payline, increasing the chances of winning, but may also require an additional bet.
Bonus Features in Classic Online Slots
Although classic online slots are more straightforward than video slots, they may still feature unique bonus elements; these include:
- Wild Symbols: These substitute for other symbols, helping to create winning combos by filling in gaps within the pay line.
- Multipliers: When present in a winning combination, multipliers will increase the payout amount by a specified factor, ranging from 2x to 5x or even higher.
- Bonus Rounds: These are separate mini-games that provide an additional opportunity to win extra prizes.
- Free Spins: These are complimentary spins that players can earn within a game, allowing them to spin without placing a bet.

Tips and Strategies for Playing Classic Online Slots
Choosing the Right Classic Slot
First, consider the theme and design of the slot. Classic slots come in various themes, such as fruits, bars, bells, or sevens. Choose a game that you like the look of.
Next, consider the number of paylines and the betting range. E.g. If you prefer lots of smaller wins, select a game with a lower number of paylines.
Pick a game with a betting range that suits your budget.
Finally, consider the special features and bonuses available in the game. While classic slots tend to have fewer bonus features than video slots, they can still offer different gameplay elements such as wild symbols, multipliers, and mini-games.
Managing Bankroll and Bet Sizes
Start by deciding how much money you’re willing to risk during your gaming session. This amount should be based on your disposable income and should be separate from your essential living expenses.
Once you’ve set your budget, choose your bet size wisely. A good rule of thumb is to only bet 1-2 % of your total bankroll on a single spin. This will extend your playtime and give you more opportunities to win.
Keep track of your spending during your gaming session and know when to stop. If you’ve reached your budget limit, take a break or switch to a free version of the game to continue playing for fun.
RTP and Volatility when Selecting Games
The RTP is the percentage of all wagered money that the slot is expected to pay back to players over time. A high RTP means the game will return a larger portion of your bets as winnings, increasing your chances of a positive outcome. Look for classic slots with an RTP of 95% or higher for the best odds.
Volatility is another factor when selecting a slot game. Slots with low volatility will provide more frequent but smaller wins, while high volatility slots will have less frequent but larger wins. Consider your personal risk tolerance and playing style when choosing.
Making the Most of Bonus Offers
To maximize your chances of winning, always take advantage of bonus offers from online casinos. These promotions range from no-deposit bonuses, free spins, and cashback to deposit match bonuses.
When using bonus funds or free spins, be strategic in your gameplay. For instance, try using them on games with higher RTPs or bet on all available paylines to increase your chances of hitting a winning combo.
Always read the terms and conditions to understand betting requirements, restrictions, and any other important details.
