Slot machines hold a central place in local casino scenes. Their presence stretches back decades, and their relevance continues to grow. The mix of straightforward gameplay and wide variety has secured their lasting place, ranging from classic three-reel setups to modern designs with inventive mechanics.

This article takes you through some of the most popular slots available at LeoVegas, whether you’re discovering them for the first time or revisiting old favourites.

The list below highlights popular titles that continue to attract attention:

Released in 2012 by NetEnt, Starburst remains one of the most widely recognised titles in online casinos. With a 5x3 reel layout and 10 fixed paylines that pay in both directions, Starburst sets itself apart through clean, accessible design. The cosmic theme comes through in crisp visuals, where colourful gems in purple, blue, red, green, and yellow appear alongside classic BAR and lucky seven symbols against a starlit backdrop.

Designed with a low to medium volatility rating, the game centres on its expanding Wild feature, which appears only on reels 2, 3, and 4. Rainbow-coloured Wilds stretch across entire reels to trigger respins, and when several land together, up to three consecutive respins can occur, with each Wild locked in place for the sequence. The maximum return reaches 500x the total stake, most often through full BAR symbol combinations.

Launched in 2006, Games Global’s Mega Moolah runs on a 5-reel, 3-row layout with 25 paylines and an African safari theme. The design features wild animals, including elephants, buffalo, giraffes, zebras, and antelopes, set against a sun-drenched grassland backdrop alongside traditional card symbols.

The Lion Wild doubles all standard combinations while substituting for regular symbols, and the Witch Doctor Scatter unlocks 15 free spins with tripled returns. A randomly triggered Wheel Bonus provides access to four progressive jackpots: Mini, Minor, Major, and the famous Mega Jackpot.

Developed by NetEnt in 2013, Gonzo’s Quest follows a conquistador’s search for treasure through ancient Mayan temples, introducing the pioneering Avalanche mechanic in place of traditional spinning reels.

Stone blocks carved with animal heads and tribal masks fall into place across 5 reels and 20 paylines, while the animated Gonzo character provides comic relief from the side of the screen. The jungle setting is reinforced by pyramid backdrops and South American-inspired audio with pan pipes and guitar melodies.

The Avalanche feature creates consecutive wins, with multipliers climbing to 5x in base play. The Free Falls bonus awards 10 spins where multipliers can rise to 15x, and maximum returns can reach 37,500x the stake during these rounds.

Released in 2016 by Play’n GO, Book of Dead is built on a 5-reel, 3-row format with 10 adjustable paylines and an Ancient Egyptian theme. The adventurer Rich Wilde leads the design, which features detailed hieroglyphics, pharaohs, gods, and sacred artefacts set against golden temple walls.

The Book symbol in this high volatility slot acts as both Wild and Scatter, substituting for other symbols and triggering 10 free spins when three land on the reels. During free spins, one symbol is randomly chosen to expand across entire reels, which can cover all positions if favourable combinations appear. Maximum returns can reach 5,000x the total stake.

Developed by Pragmatic Play and released in 2021, Buffalo King Megaways reimagines the North American prairies in a 6-reel format that can generate up to 200,704 ways to win. The backdrop of canyons and sweeping sunsets frames symbols of buffalo, eagles, cougars, wolves, and moose, supported by an Americana-inspired soundtrack.

Tumbling reels form the core mechanic, removing winning symbols and dropping new ones until no further combinations appear. Wild symbols with 2x, 3x, or 5x multipliers intensify these cascades, and the Free Spins feature awards 12, 17, or 22 spins. During this round, multiplier Wilds combine their values across sequences. Maximum returns in this high volatility slot reach 5,000x the total stake.

Released in 2019 by Pragmatic Play, Sweet Bonanza creates a confectionery landscape on a 6x5 grid with Scatter Pays mechanics, where eight or more matching symbols form wins regardless of position. Pastel backdrops of cotton candy clouds and chocolate tones set the scene, with fruit symbols including bananas, grapes, watermelons, plums, and apples sharing the reels with bright candy hearts.

Tumbling mechanics clear winning combinations and drop new symbols until no further matches appear. The Lollipop Scatter unlocks 10 free spins in this medium-to-high volatility slot, during which Rainbow Bomb multipliers worth up to 100x can land and apply to all tumbles within a spin.

When several Rainbow Bombs appear together, their values are combined, and three or more Scatters during the feature add five extra spins. Maximum potential returns can reach 21,100x the total stake.

Brought out by Reel Kingdom in 2020, Big Bass Bonanza unfolds across 5 reels, 3 rows, and 10 paylines. The medium-to-high volatility slot offers maximum returns of up to 2,100x the total stake.

Cartoon-style graphics depict a deep blue underwater setting with aquatic plant life, accompanied by a light jazz-inspired soundtrack that complements the relaxed fishing theme. Standard card symbols appear alongside fish, tackle boxes, dragonflies, fishing rods, and colourful floats.

The Free Spins feature anchors the gameplay, awarding 10, 15, or 20 spins depending on the number of Scatters. During free spins, Fisherman Wilds collect cash values from Money Fish symbols.

Every four collected Wilds retrigger 10 additional spins and raise the multiplier on collected fish values, climbing as high as 10x. A Dynamite modifier may also trigger, adding Money Fish to the reels when Wilds appear without them.

Released by Pragmatic Play in 2017, Wolf Gold is built on a 5x3 layout with 25 paylines and a Native American-inspired desert theme. The canyon backdrop is paired with tribal soundscapes, while detailed animal symbols include buffalo, eagles, mustangs, and cougars alongside standard card values. Classified as a medium volatility slot, the game offers maximum potential returns of 2,500x the stake.

Three progressive jackpots (Mini, Major, and Mega) are linked to the Money Respin feature, which activates when Full Moon symbols land. Canyon Scatters trigger five free spins, during which reels 2, 3, and 4 combine into giant symbols. The Hold & Win mechanic continues as long as new Money symbols appear, with all 15 positions filled awarding the Mega Jackpot.

Designed and released by Relax Gaming in 2019, Temple Tumble Megaways presents an Aztec-inspired temple adventure with high volatility gameplay across a 6x6 grid and up to 46,656 ways to win.

Stone blocks obstruct the reels and are cleared through adjacent wins, revealing hidden areas and unlocking bonus features. The jungle backdrop is enriched with ceremonial flames and ancient sculptures that frame the action.

The main feature is triggered by removing all blocking stone symbols, opening an underground chamber of free spins. Three modes are available: Extra Spins for medium volatility, Multipliers & Extra Spins for high volatility, and Multipliers only for very high volatility. Special stone blocks during free spins may reveal extra rounds or multiplier boosts, depending on the chosen mode.

Launched in 2019 by Gameburger Studios for Microgaming, 9 Masks of Fire is built on a 5-reel, 3-row layout with 20 paylines. The medium volatility slot blends a fiery African-inspired backdrop with classic slot symbols, featuring lucky 7s, bells, cherries, bars, dollar signs, and diamonds as Wilds. The signature mask Scatters provide direct scatter pays when several appear across the reels.

Bonus features include free spins triggered by shield symbols and a prize wheel that can add multipliers, while mask Scatters deliver instant cash prizes. Maximum returns can climb to 6,000x the stake.

LeoVegas’ favourite slots come from some of the biggest names in the industry. Here are some of the most popular ones:

Established in Sweden in 1996, NetEnt has grown into a leading name in online slots, recognised for polished presentation and inventive design. The company’s catalogue combines cinematic visuals with reliable performance across desktop and mobile play.

Highlights include Starburst and Gonzo’s Quest, two titles that remain enduring favourites. The studio has also created branded games, including Narcos and Jumanji.

Founded in 1994, Microgaming is one of the most established names in online casino software. The company is best known for its extensive catalogue of progressive jackpot slots, including the Mega Moolah series, which has set Guinness World Records for the largest online slot wins.

Microgaming also operates the Quickfire platform, which distributes content from independent studios like Just For The Win and Stormcraft Studios.

Launched in 2015, Pragmatic Play is a newer studio compared to long-standing providers like Microgaming, yet it has established a strong presence in the online casino space. The company is known for releasing new titles frequently, with a portfolio that spans a wide mix of themes and bonus mechanics.

Popular creations include Sweet Bonanza, Wolf Gold, Rise of Olympus, and the Big Bass series, all of which are available at LeoVegas.

Based in Sweden, Play’n GO has been developing slot content since the mid-1990s and was officially established as a company in 2005. Over the years, the developer has become a major name in online casino software.

The studio’s flagship title, Book of Dead, is considered one of the most iconic slots worldwide. The studio’s wider catalogue includes well-known releases like Reactoonz and Fire Joker.

Founded in 2014, Red Tiger was acquired by NetEnt in 2019 and later became part of Evolution in 2020. These moves expanded the studio’s global reach and integrated its content into a wider network of operators.

Red Tiger is known for titles including Reel King Mega, Dynamite Riches, Rainbow Jackpots, and Piggy Riches Megaways. The studio also develops promotional tools, including daily jackpots, tournaments, and prize drops that are widely used across online casinos.

Established in 2013, Yggdrasil Gaming has built a strong reputation in online slot development, with early successes including Vikings Go Berzerk and Holmes and the Stolen Stones, the latter notable for its collection-based jackpot feature.

The portfolio is defined by distinctive visuals and carefully designed themes, supported by proprietary mechanics including Splitz (symbol-splitting), Gigablox (oversized symbols), and MultiMax (progressive multipliers).

LeoVegas offers a tiered welcome bonus for verified new accounts, valued at up to $2,000 and 200 free spins on MGM Grand Gamble. The package is divided across the first three deposits, each linked to a specific “deposit card” and claimed via the My Offers page.

• First deposit card: Up to $500 in matched funds and 50 free spins

• Second deposit card: Up to $500 in matched funds and 50 free spins

• Third deposit card: Up to $1,000 in matched funds and 100 free spins

A minimum deposit of $10 is required to activate a deposit card, while the free spins are only credited if the deposit is $50 or more. To release each bonus and its spins, the deposit made for that card must be wagered 20x on eligible casino games, and the offer must be activated and completed within seven days of joining.

Once the first card is cleared, the second becomes available, followed by the third. The free spins are tied to MGM Grand Gamble at $0.20 per spin. For instance, depositing $200 on the first card and completing the 20x wagering requirement results in $200 in bonus funds along with 50 spins on the slot. This structure scales the welcome package across multiple deposits instead of delivering it in one instalment.
