Best Progressive Slots

Welcome to our list of the best progressive slots available right now. Each game has been assessed against verified RTP figures where available, jackpot structure, bonus mechanics, and real availability at regulated UK and EU operators or established US-facing offshore casinos. Progressive slots are real-money online slot games where the jackpot grows with every spin, often reaching life-changing prize totals.

What Are the Best Progressive Slots Online?

Firstly, there are hundreds of excellent progressive slots online. These types of slots can change your financial fortune overnight, but you’ll still need Lady Luck to visit. The lineup below spans twelve titles available at UK and EU regulated operators alongside three picks for US-facing offshore casinos, with verified jackpot networks across Microgaming, NetEnt, Playtech, Yggdrasil, Blueprint Gaming, RTG, and Betsoft.

Mega Moolah

• Release Date: 2006
• Provider: Microgaming
• Progressive Jackpots: 4 (Mini, Minor, Major, Mega)
• RTP: 88.12% base / 93.42% total including jackpot contribution
• Best Feature: Random Jackpot Wheel

Mega Moolah by Microgaming is the most iconic progressive jackpot slot ever created. The African safari theme has become a household name across hundreds of online casinos worldwide, and the four-tier jackpot wheel structure (Mini, Minor, Major, and Mega) has produced some of the largest payouts in online casino history, including a record £19.4M win at a UK operator and a €19.4M Belgian payout.

The Mega progressive jackpot seeds at £/€$1,000,000 and typically drops every 8 to 10 weeks. The jackpot is triggered randomly during any spin via the Bonus Wheel, where players spin to land on one of the four jackpot tiers. The base RTP of 88.12% is low because a substantial portion of every wager funds the network jackpot, but the total RTP including jackpot contribution rises to 93.42%. Outside the jackpot bonus, the free spins round delivers 15 free spins with all wins tripled and Lion Wilds doubling additional payouts. Play Mega Moolah at Casumo for one of the most consistent UK-licensed deployments of the title.

Mega Fortune

• Release Date: 2008
• Provider: NetEnt
• Progressive Jackpots: 3 (Rapid, Major, Mega)
• RTP: 96.60%
• Best Feature: Bonus Wheel with 3-Tier Jackpot Structure

Despite being more than 15 years old, Mega Fortune by NetEnt is still one of the best progressive slots online. This game oozes character and will make you feel like a millionaire when you open it. Symbols consist of a range of luxurious items, including watches, jewellery, cars, and champagne, set against a yacht-themed backdrop that captures the high-roller aesthetic the studio is known for.

In terms of progressive jackpots, there are three to play for. The smallest is the Rapid jackpot, the middle is the Major jackpot, and the biggest is the Mega jackpot. To put this into context, a lucky player won €17,861,813 (approximately £15.8M) back in January 2013, making it one of the largest verified online slot wins on record. The Mega tier hits an average of every 90 to 110 days. The 96.60% RTP is one of the highest in the progressive jackpot category, where most titles trade RTP for jackpot contribution. Two additional features layer the gameplay: a free spins bonus and an instant cash wheel that awards prizes when triggered. Play Mega Fortune at PlayOJO for the most direct UK-licensed access.

Divine Fortune

• Release Date: 2017
• Provider: NetEnt
• Progressive Jackpots: 3 (Minor, Major, Mega)
• RTP: 96.59%
• Best Feature: Falling Wilds Re-Spins + Three-Tier Jackpot

Divine Fortune is one of NetEnt’s strongest mid-2010s progressive releases and a clean example of how the studio modernised the genre after the success of Mega Fortune. The Greek mythology theme runs across detailed character art including Pegasus, Medusa, lions, and bulls, set against a cloudy backdrop with statue framing on either side of the reels. The progressive jackpot is “local” rather than networked, meaning each casino’s pot grows independently, which produces lower ceilings than Mega Moolah but more frequent drops.

Three jackpot tiers structure the bonus path: Minor, Major, and Mega. The Mega progressive seeds at £10,000 and grows with every spin until won, with average drops in the low six figures. The jackpot bonus is triggered by collecting Bonus symbols across the reels, with three or more activating the Jackpot Bonus Game where players match coin symbols on a 4×5 grid to determine the prize tier. The Falling Wilds Re-Spin feature is the standout base game mechanic: when a wild symbol lands, it drops one position per re-spin until it leaves the grid, awarding consecutive payouts.

Hall of Gods

• Release Date: 2010
• Provider: NetEnt
• Progressive Jackpots: 3 (Mini, Midi, Mega)
• RTP: 95.7%
• Best Feature: Free Spins with 3x Multiplier

Hall of Gods is one of NetEnt’s longest-running progressive jackpot releases and a genuine benchmark in the Norse mythology slot category. The 5-reel grid features Thor, Odin, Loki, and Freyja as high-paying symbols alongside the studio’s signature 3D-style art direction. The 95.7% RTP is generous for the progressive category, and the title has paid out more than £/$90M in jackpot wins across its lifespan.

The bonus structure follows the standard NetEnt three-tier model with Mini, Midi, and Mega progressives. Players trigger the jackpot bonus by landing three of Thor’s hammers across the reels, which opens a pick-style mini-game where shields hide one of the three jackpot tiers. The free spins feature awards up to 20 free spins with all wins tripled, and an instant win pick game runs alongside the main jackpot bonus. The combination of three layered features and a relatively low jackpot trigger threshold has kept Hall of Gods popular for over a decade.

Major Millions

• Release Date: 2009
• Provider: Microgaming
• Progressive Jackpots: 1 (Single Networked Progressive)
• RTP: ~89%
• Best Feature: Single-Tier Networked Progressive

Major Millions is one of the most popular Microgaming slots. Unlike newer progressive slots with multi-tier jackpot structures, this title runs a single networked progressive that has been growing across Microgaming-licensed casinos for over 15 years. It’s also the page’s most accessible entry for low-stakes players: you don’t need to wager high amounts to qualify for the jackpot trigger.

This game doesn’t have many fancy features. It’s all about landing the big win. Players can enjoy basic wild symbols and straightforward three-of-a-kind paylines. Major Millions is a classic example of rudimentary but functional gameplay. It wouldn’t have survived for this long if it wasn’t worth a few spins, and the simplicity makes it an entry-point progressive for players new to the category. The military theme runs across general’s stripes, medals, and tank symbols, set against a flag-and-trumpet backdrop that captures the era of late-2000s Microgaming releases.

Starlite Fruits: Mega Moolah

• Provider: Microgaming
• Betting Limits: $/£0.10 – $/£200
• Progressive Jackpots: 4 (Mega Moolah Wheel)
• RTP: 97.08%
• Best Feature: Progressive Wheel + Expanding Wilds

Mega Moolah by Microgaming is considered to be one of the world’s most popular progressive slots, and Starlite Fruits is one of the most polished variants in the franchise. The classic fruit symbol set fills the reels (grapes, cherries, oranges, lemons, watermelons, 7s, gold bars, and star fruits) and reframes the Mega Moolah jackpot wheel as a fruit machine update.

There are 10 active paylines across five reels. The base game jackpot is 500x your total stake, but the main aim of this game is to trigger a life-changing progressive. Starlite Fruits: Mega Moolah has a 97.08% RTP, the highest verified RTP across this entire progressive lineup, and one of the highest RTPs in any Mega Moolah variant. The expanding wilds appear across the reels and stretch to cover entire reels, triggering a respin with all wilds locked in place. The progressive wheel appears when diamond progressive symbols are collected. When triggered, the wheel determines which of the four progressive jackpots is won, with the Mega tier seeding at $/£2 million.

Arabian Nights

• Release Date: 2005
• Provider: NetEnt
• Progressive Jackpots: 1 (Single Networked Progressive)
• RTP: 95.6%
• Best Feature: Free Spins with Multipliers

Arabian Nights by NetEnt is one of the most popular progressive slots around. This classic was released back in 2005 and remains a fixture at NetEnt-powered casinos two decades later. The old-school symbols and graphics will take you on a trip down memory lane, with magic lamps, jewellery, sultans, and palace imagery running across a clean five-reel grid.

The progressive jackpot is triggered by landing five wild Arabian symbols across an active payline. Additionally, you can give your balance a boost with the free spins bonus. All you need to do is land three or more scatters. The best part is that you can win as many as 30 free spins with multipliers across the round. If you’re looking for a classic game with huge payouts, Arabian Nights is made for you. Note that if you’re looking to play in slot tournaments, you won’t find these games. Most operators don’t offer jackpot slots in those as the risk of you winning a massive multi-million payout is too much. These are always pay-to-play games, and the RTP on them is usually a little steeper than traditional slots to fund the jackpot.

Book of Atem WowPot

• Release Date: 2020
• Provider: All41 Studios / Microgaming
• Progressive Jackpots: 4 (WowPot Network)
• RTP: ~94%
• Best Feature: WowPot Progressive Bonus + Expanding Symbols

Book of Atem WowPot is among the best progressive slots on the market and a flagship entry in the Microgaming WowPot network, which has paid out some of the largest verified wins in online casino history. The Ancient Egyptian theme features playing cards A-10 alongside flowers, snakes, falcons, and Pharaohs, with the latter as the highest-value symbol. The book icon is the wild and triggers the free spins round.

The four-tier WowPot jackpot structure is the title’s primary draw. The progressive bonus triggers randomly during gameplay and presents a wheel with four jackpot levels. The objective is to win the WowPot tier, and for context, a lucky player took home €17,549,047 in April 2021, making it one of the largest verified online slot wins ever recorded. The base game free spins round is triggered by three or more scatters, awarding 10 free spins with an expanding symbol that pays as if it covers every position when it lands. The 94% RTP is lower than most modern slots because of the jackpot contribution, but the trade-off has produced multiple eight-figure payouts across the network.

Age of the Gods: Wonder Warriors

• Release Date: 2021
• Provider: Playtech
• Progressive Jackpots: 4 (Power, Extra Power, Super Power, Ultimate Power)
• RTP: 96.44%
• Best Feature: Variable Ways + Four-Tier Network Progressive

Playtech’s Age of the Gods series brings us some of the most-played slots with Ancient gods themes. The Wonder Warriors edition is jam-packed with captivating features and immense progressive jackpots. You’ll find a dozen symbols on the paytable, including playing cards A-Q, a helmet, Aphrodite, Hades, Hercules, Poseidon, Zeus, and Athena. The scatter is an Age of the Gods logo.

Age of the Gods: Wonder Warriors is a variable ways slot. There could be anything from 3 rows and 243 paylines to 6 rows and 7,776 paylines active each time you spin the reels. This is completely random and will fluctuate as you play. The 96.44% RTP places it among the highest in the progressive category. The free spins feature is activated by landing three or more scatter symbols on the reels, and the Variable Ways feature presents four options to choose from: 15 free spins with 243 paylines, 10 free spins with 1,024 paylines, 5 free spins with 3,125 paylines, or 3 free spins with all 7,776 paylines active.

All Age of the Gods releases share the same four-tier progressive network across the entire series, meaning every spin on every Age of the Gods slot contributes to the same jackpot pool. The Ultimate Power Jackpot is the pinnacle, starting at £/$100,000 and ticking over until won. The shared liquidity across the series means jackpots build faster than standalone progressives.

Jackpot Giant

• Release Date: 2013
• Provider: Playtech
• Progressive Jackpots: 1 (Single Max-Bet Progressive)
• RTP: 94.21%
• Volatility: High
• Best Feature: Volcano Bonus + Max-Bet Progressive

Jackpot Giant is Playtech’s prehistoric-themed standalone progressive and the page’s only entry that requires a maximum bet to qualify for the jackpot. Stakes start at relatively modest levels, but to win the progressive jackpot, players must bet the maximum (typically £/$4 per spin) AND land five Wild symbols on the central payline. This double-condition trigger keeps the jackpot growing for extended periods, with the all-time peak reaching £9.4M before a UK player landed it in 2019.

The 3D graphics depict a friendly cartoon Giant character, and the prehistoric jungle theme runs across cavemen, crystals, stone monoliths, and jungle plant symbols. The Volcano Bonus feature triggers when bonus symbols appear on reels 1 and 5, presenting a pick-me game where players select volcanoes to reveal cash prizes. The base game also includes stacked wilds across the reels for additional payout potential. The average jackpot drop sits at £4.5M every 155 days, with the strict max-bet requirement meaning that players must commit to a substantial session bankroll to participate in the progressive at all. Play Jackpot Giant at Mr Green for one of the most consistent UK-licensed deployments.

Holmes and the Stolen Stones

• Release Date: 2015
• Provider: Yggdrasil Gaming
• Progressive Jackpots: 5 (Local Tier Progressives)
• RTP: 96.80%
• Volatility: Low-Medium
• Best Feature: Five-Tier Diamond Shard Collection + Jackpot Free Spins

Holmes and the Stolen Stones is Yggdrasil’s flagship progressive jackpot slot and one of the most mechanically distinctive entries in the entire category. The Sherlock Holmes Victorian London theme runs across detailed Holmes and Watson character art alongside card-suit-and-gemstone symbols, and the 5-reel grid uses 20 paylines. The 96.80% RTP is one of the highest among all progressive slots, well above the genre average and making this a strong long-session option even before the jackpot mechanics are factored in.

The defining mechanic is the five-tier local progressive jackpot structure, with each tier represented by a different colored diamond (Yellow, Red, Green, Blue, Purple). Diamond shards drop randomly above each reel during base play and persist across spins, building toward the Jackpot Free Spins feature. When players collect five same-color shards or land three Free Spin scatters, the Jackpot Free Spins round triggers with a 3x multiplier on all wins. Collecting five full diamonds of the same color during free spins wins the corresponding progressive jackpot tier, ranging from a €40 seed up to €30,000+ on the highest tier. The Warehouse Bonus pick-me game adds a third bonus feature with cash prizes and additional shard rewards. Play Holmes and the Stolen Stones at NetBet for direct UK/EU access.

Fishin’ Frenzy: Jackpot King

• Provider: Blueprint Gaming / Reel Time Gaming
• Progressive Jackpots: Networked (Jackpot King Network)
• RTP: ~88% base / ~94% including jackpot contribution
• Volatility: High
• Best Feature: Cash Collect Fisherman + Wheel King Progressive

Fishin’ Frenzy: Jackpot King is Blueprint Gaming’s integration of one of the UK’s most popular fishing-themed slot brands with the studio’s network progressive jackpot system. The base game preserves the original Fishin’ Frenzy formula (six paylines, fishing theme, Cash Collect free spins) and layers the Jackpot King network on top, giving players a shot at multimillion-pound jackpot wins from a familiar gameplay format.

The progressive trigger requires landing five Jackpot King crown symbols, which activates the Ladder mini-game. Players climb the ladder one rung at a time, with each step offering the choice to bank the current cash prize or risk it for the next rung. The top of the ladder leads to the Wheel King, a wheel spin that determines the final jackpot tier won, including the network’s top progressive. The Cash Collect Fisherman feature during free spins adds the standard Fishin’ Frenzy mechanic where the Fisherman symbol catches all visible fish symbols and adds their values to the winning total. The base RTP is approximately 88% (lower than the standalone Fishin’ Frenzy because of jackpot contribution), with the total RTP including jackpot contribution rising to roughly 94%. Play Fishin’ Frenzy: Jackpot King at NetBet for direct UK access to the Jackpot King network.

Aztec’s Millions

• Release Date: 2009
• Provider: RTG
• Progressive Jackpot: 1 (Networked, $1M+ Seed)
• Betting Limits: £/$0.20 – £/$5
• RTP: ~94%
• Best Feature: Free Spins with 3x Multiplier

If you fancy a shot at one of the top progressive slots for American players, look no further than Aztec’s Millions by RTG. Despite being released in 2009, this game still has plenty to offer. Symbols on the paytable include playing cards A-9, a gold brooch, a bracelet, Native American headwear, a leopard, and the Aztec Queen. The wild and bonus symbols also play major roles, with the Aztec Queen acting as the highest-value symbol on the grid.

The minimum bet per spin is £/$0.20. If you want to up the ante, you can wager as much as £/$5 per spin. The estimated RTP is 94%, which is consistent with most networked progressive slots in the category. There are two bonus features. For instance, you could trigger as many as 25 free spins if all five Aztec King scatter symbols appear across the reels at once. All wins accumulated during this round are tripled for good measure.

The main event is the mammoth progressive jackpot. You will land it if all five Aztec’s Millions logos appear simultaneously across an active payline. The networked progressive seeds at $1,000,000 and consistently builds beyond that figure across the RTG offshore network, making this one of the most accessible million-dollar-plus progressives at US-facing casinos.

Tycoons

• Release Date: 2015
• Provider: Betsoft
• Progressive Jackpots: 1 (Random Progressive)
• RTP: 95.34%
• Volatility: Medium
• Best Feature: Poker Bonus + Random Progressive

Betsoft is renowned for creating some of the world’s best progressive slot machines, and Tycoons meets the criteria. It has several high-class features and a substantial random progressive jackpot. The main symbols include a wealthy man, a wealthy woman, a Sheikh, a premium bottle of champagne, a bundle of cash, gold bars, a red Ferrari, and a credit card, set against the studio’s signature 3D animation polish.

The 95.34% RTP is solid for the progressive category, and the medium volatility means players experience frequent payouts during extended sessions, though dry spells remain possible. Tycoons has a handful of exciting bonuses. You could collect instant cash prizes through the Click Me feature triggered by bonus symbol alignments. The Poker bonus is the standout: it occurs when three or more bonus symbols appear across the reels, and players predict which Tycoon will win the hand. Successful predictions add cash prizes to the balance.

The progressive jackpot can be triggered randomly during any spin, with the total ticking over at the top of the reels throughout the session. The random trigger means the progressive doesn’t require a specific symbol alignment or max-bet condition, making it accessible at every stake level Betsoft offers.

Cash Bandits: Museum Heist

• Release Date: 2023
• Provider: RTG
• Progressive Jackpots: 2 (Random Progressives)
• Betting Limits: £/$0.25 – £/$25
• RTP: ~95%
• Volatility: High
• Best Feature: Wild Morphing + Museum Heist Free Spins with Boosters

RTG is renowned for creating remarkable progressive slots, and the studio has exceeded its own high standards with the release of Cash Bandits: Museum Heist. The paytable is jam-packed with valuable symbols including gemstones, jewellery, Faberge eggs, sculptures, paintings, and gold crowns. The male and female museum employees are the symbols with the highest value, anchoring the heist narrative across the reels.

This slot is suitable for every bankroll. If you want to play for fun, the minimum bet per spin is £/$0.25. However, if you’re aiming for a monstrous win, you can bet as much as £/$25 per spin. This slot is highly volatile. The estimated RTP is 95%. Two life-changing progressive jackpots are up for grabs, both ticking over above the reels and triggered randomly during any spin.

If your pursuit of a progressive is unsuccessful, two fantastic bonus features keep the gameplay interesting. The Wild Morphing bonus may turn wild symbols into 3×3 colossal symbols, and when these expand to cover large portions of the reels, alignment with high-value icons can produce session-defining wins. The Museum Heist feature is the standout. You can win 5 free spins when three scatters appear, 7 free spins for four scatters, and 9 free spins for five scatters. The number of scatters also determines the boosters you receive: three scatters award 1 booster, four scatters award 2 boosters, and five scatters award 3 boosters. Boosters can trigger 2x, 3x, 4x, or 5x multipliers, wild reels, or a center 3×3 expanding wild during the bonus round.
