In the past few years, modern video slots took over old-fashioned, so called classic slots. They have become the go-to choice for many players, particularly those who enjoy an immersive story complemented by numerous bonus features and impressive graphics. But at Unibet, we also know the value of playing classic slots, the ones that take you back in time to land-based casinos and 3-reel machines.
The reason why classic slots online are still a good option is that the simplicity they offer is something you won’t find in any other game. The games are not burdened by heavy animations, extra features, or complicated paytables. So, it’s essentially you and your wager against 3 reels on a simple background.
What are Classic Slots?
Classic slots are slot games that resemble traditional slot machines, with symbols like fruits, stars, bells, and 7s. They’re usually played on a very simple 3×3 grid with just 3 rows and 3 reels, and they don’t include any special features like free spins, bonus rounds, multipliers, or similar. In most cases you’ll find one to a handful of fixed paylines—often just the centre line—so wins are all about lining up matching symbols in a straight, no-nonsense way.
The symbol set is intentionally small and familiar, the spin pace is faster, and the paytable is easy to read at a glance. Some titles may add a single wild or a modest “nudge/hold” style mechanic, but the focus stays on simple spins and straightforward payouts. Because there’s less happening on screen, classic slots tend to feel snappier on mobile and are great if you prefer shorter sessions, a clearer view of your gaming budget, and that nostalgic fruit-machine vibe you’d expect from land-based casinos.
Our Top Picks for Classic Slots Lovers
In today’s guide, we will tell you more about the classic slots that are still worth playing, giving you a quick overview of the features these games offer. So, stick around if you want to learn more about the 10 standout classic slots at Unibet Casino available in demo mode and for real money wagers.
Fire Joker – Play’n GO
Fire Joker is a 2016 release by Play’n GO that features the standard look of classic slots online, with 3 reels and minimal features. You can expect to see familiar symbols on the reels, including the bar symbol, 7s, stars, grapes, lemons, cherries, etc. The Joker can appear as the wild, helping form one of the five possible paylines more easily. The most you can win on this classic slot is 800x your wager.
Cleopatra – IGT
IGT created one of the most popular classic slots for 2015, and we still notice that many of our players return to this slot because of its rewarding yet straightforward nature. The RTP is set at 95.02%, which is slightly below the industry standard of 96%, but it can still yield a great return. At medium volatility, wins might come regularly, but they won’t be very big. If you want a bigger winning potential, try to trigger more Cleopatra wilds and bonus symbols, as the former can help form one of the 20 paylines on this classic slot, while the latter can give you free spins.
Mega Joker – Greentube
Even though it’s not one of the 3-reel classic casino slots you’re used to seeing, everything about this game will take you back in time to retro slots with minimal features. The grid features 5 reels, but the overall design fits the classic slots description due to the fruit symbols, star scatters, and the Joker, which appears as the highest-value symbol. The RTP is set at 95.05%, and there are 40 lines in total, which can help you land the maximum payout.
Starburst – NetEnt
If you’re looking for classic slots, you can’t go wrong with Starburst, which remains one of the most popular online slots available. It has simple gameplay with a high return to player rate of 96.09%. The best part of this classic slot is the low volatility, meaning that you can expect wins to land regularly. To get the chance to trigger one of the 10 paylines that pay both ways, you can use wilds that substitute for each symbol or expanding wilds that can trigger respins.
Charlie Chance in Hell to Play – Play’n GO
We can classify this as one of the classic slots due to its 3×3 grid populated by retro symbols, such as fruits and 7s. However, there’s a lot more to it. For example, you can trigger several bonus features that include instant prizes, multiplier respins, wild respins, and free spins. At a 94.79% RTP and medium volatility, the return is fair, while the most you can win is up to 6,666x your bet.
Shadow Society – Red Tiger Gaming
Unlike classic casino slots that are simpler, the Shadow Society slot is more advanced, especially if you focus on the graphics. However, the game begins as a standard 3×3 slot with only 9 set paylines, offering the chance to expand it into a 4-row or 5-row game and increase the possible paylines to 25. Using the scatter symbol, you can trigger free spins for a chance to save your budget but still make more spins. It’s up to you to decide on the wager size, which starts from £0.20.
Big Bass Bonanza 3 Reeler – Pragmatic Play
If you’re looking for classic slots online with a little twist, then Big Bass Bonanza 3 Reeler is the title to look into. This classic slot is actually part of a larger series of fishing-themed slots you’ll find at our online casino. In this specific slot, you can expect an RTP of 96.50% and high volatility, paired with a max win of 5,000x your wager. This is one of the rare classic slots that combines traditional 3-reel play with the added fun of a free spins round.
Rabbit Hole Riches – Play’n GO
As one of the popular classic slots featured at Unibet, you should check out Rabbit Hole Riches if you’re a fan of the Alice in Wonderland storyline. In this game, you can expect wagers starting at £0.10 and a max win of 5,000x your bet. Five paylines can appear across the 3×3 grid of this classic casino slot, but that’s not the most exciting feature – it’s the opportunity to trigger bonus games with scatter symbols, as well as land the bonus features such as Teacup Party, Cheshire Cat, Tower Power, and Queen’s Army.
Sticky Joker – Play’n GO
Another popular classic slot online, following the Joker theme, this game features a 3×3 grid with a straightforward paytable. As a fruit classic slot, you can find the standard selection of fruit symbols accompanied by 7s, stars, bar signs, etc. The Joker appears as the wild symbol and can replace any other symbol to trigger respins. But even without the bonus features, this classic slot would be very rewarding, considering the possible winning outcome is up to 1,650x your wager.
Cherry Red Retro Roller – Games Global
The final classic slot we have to recommend is this Games Global release from last year. From the moment you launch Cherry Red Retro Roller, you’ll feel like you are playing an actual slot machine with a 3×3 grid and the retro bar symbols. There are no bonus rounds in this classic slot, but there is a twist. The cherries appear as the wild symbol and can substitute all other symbols, rewarding multipliers of up to 4x on a winning line.
Few Types od classic slots to choose from
Since classic slots online are all about simplicity, there aren’t many different types. The most common types are 3-reel slots, which are the purest form of old-fashioned classic slots and often feature 1 to 5 paylines.
Another type are 5-reel classic slots, which keep the simplicity, but adds more reels, thus more symbols and more paylines.

Classic slots vs modern video slots: Which ones are better?
Classic slots keep the three-reel “fruit machine” feel and focus on fast, readable outcomes. Fire Joker (Play’n GO) and Sticky Joker (Play’n GO) are quintessential examples: 3×3 layouts, tight symbol sets, simple wilds and quick spin cycles. By contrast, modern video slots amplify story and features. Even titles that borrow classic aesthetics—like Starburst (NetEnt) with expanding wilds and both-ways pays, or Rabbit Hole Riches (Play’n GO) with multiple themed bonus games—belong in the video camp because their features, pacing and audiovisuals are far richer. Players wanting pure retro rhythm and rapid results gravitate to Fire Joker or Mega Joker (Greentube), while those who prefer cinematic features and set-piece bonuses try Starburst, Charlie Chance in Hell to Pay (Play’n GO) or Shadow Society (Red Tiger), which starts like a classic 3×3 but can expand to a fuller grid mid-session.
How classic slots work (reels, paylines, payouts)?
Most classics run on a 3×3 grid with one to five fixed lines. You stake, spin and get paid for straight-line matches; wilds, when present, substitute to complete lines. Fire Joker demonstrates this perfectly: line up 7s, bars or stars across five fixed lines, and the Joker wild helps bridge gaps.
Sticky Joker adds a light twist with sticky wilds and re-spins, but the core remains about lining up symbols on a tiny grid. If you prefer a slightly broader canvas without losing the old-school vibe, Mega Joker uses more lines and a retro symbol set to keep outcomes legible while adding a bit more line coverage. Cleopatra (IGT) sits on the edge of “classic feel” with straightforward pays, recognizable symbols and a simple free spins trigger, so newcomers still find it easy to follow. In all cases, paytables are short enough to memorize in a minute, so you always know what three bells, bars or 7s are worth.
RTP, volatility and bankroll tips for classic slots — illustrated
RTP is the theoretical long-run return and volatility is the win pattern. Fire Joker pairs a classic grid with punchy, medium-ish volatility; you’ll see frequent line hits with occasional spikes when the multiplier wheel lands. Sticky Joker trends toward frequent, modest hits because sticky wilds can chain short re-spin sequences. Starburst, although more “video,” is famous for low volatility and regular small returns, so it’s a good comparative benchmark if you want relaxed sessions.
If you’d like more swing while staying compact, Big Bass Bonanza 3 Reeler (Pragmatic Play) layers high volatility and a free-spins round onto a 3-reel base; expect dry spells punctuated by bigger peaks. For budgets, align stake size with volatility: on steadier games like Sticky Joker or Starburst, smaller but steady wins support longer sessions at modest stakes; on swingier titles like Big Bass Bonanza 3 Reeler, shorten sessions, keep stakes conservative, and pre-define a hard stop. Always treat re-spins, nudge/hold effects or multiplier wheels as variance boosters rather than guarantees.
How to choose a classic slot at Unibet?
Start with theme recognition and paytable clarity—if you like pure fruit-machine vibes, pick the simplest 3×3 with the fewest extras. Check RTP and volatility on the game info panel to match your preference for steady hits or swingy sessions. Look at max win potential and any light-touch mechanics (wilds, re-spins, multiplier wheels) that add excitement without turning the game into a full video slot. Finally, test in demo first to feel the spin speed, reel rhythm and line frequency, then switch to real-money play once you’ve found your pace.
The appeal of classic slots lies in their simplicity. They resemble those old-school fruities where you need to pull the lever to spin, and the symbols are the classic bells, fruits, and stars. No added features, no bonus rounds, no complicated free spins or tumbling reels. It’s all plain, simple, and easy to understand.
