What is a progressive jackpot slot game?

Progressive jackpot video slots are interactive slot games with massive prize pools which can be won by any real money player spinning the reels. The jackpot prize pools accumulate based on the number of players playing the game, with a certain amount of their money going towards what is known as a network-wide jackpot.

Progressive titles are typically hosted at several distinct online and mobile casinos, so players from all across the globe are constantly funding the prize pools at any given time, and this is what is meant by a network-wide money pool.

For example: any one particular game, such as Microgaming’s Mega Moolah, can be accessed at numerous different regulated gaming sites, with its jackpots continually increasing from the hundreds of thousands of people playing, all of who share the knowledge that they are in the running to spin that lucky combination, or move through to the bonus round at complete random, for a shot at taking home the entire jackpot, or part there of.

And once a jackpot is won, it will reset to a predetermined base amount (such as $1,000,000), and then begin accumulating again. So let us take a look at some of the most popular online and mobile-compatible accumulative jackpot video slots, how their prize pools can be won, and roughly how high the jackpots can reach.

Largest and most popular online progressive slots

Leading gaming software developers such as Microgaming, Net Entertainment and BetSoft all boast games which feature progressive prize pools, where players can join in the fun for a chance at winning big, with minimal wagers per spin. The following titles are the progressives with some of the largest real money jackpot totals online.

Microgaming progressive jackpot slots

Microgaming’s Mega Moolah – Mega Moolah is touted as the ‘The Millionaire Maker’ among online casino players, and has four unique progressive jackpots: mini, minor, major and mega. The mini begins increasing from $10, the minor kicks off from $100, the major starts counting upwards from $10,000 and the mega will never go below $1,000,000. Each resets to its base level when someone wins the jackpot. Players can win any of the jackpots at any stage during gameplay: the bonus round is triggered at random, and is a wheel-of-fortune/roulette type feature, with pockets reserved for each of the four jackpots (one for the mega, three for the major, six for the minor and 10 for the mini). An African safari-themed slots game which is calming and quaint, you can play the title at Jackpot City Casino.

Microgaming’s Major Millions – While not as lucrative as the Mega Moolah games, the Major Millions progressive prize pool is won more frequently than the mega jackpots within the other two titles. A five-reel and 15-payline online slot with an army theme, the sole jackpot often hovers around the $500,000-mark and is won when five ‘Major Millions’ symbols are spun on the 15th payline. Players can view the paylines within the payout and game information chart featured within the game. Play Major Millions at Royal Vegas Casino.

Net Entertainment progressive jackpot slots

Net Entertainment’s Arabian Nights – Arabian Nights is a five-reel and 10-payline slot game based on the world of Arabian Nights in the Islamic world of the ninth to thirteenth centuries. The sole accumulative prize pool which the game owns can only be won if a player places the maximum wager (of 10 paylines) and five ‘Wild’ symbols are spun on any one of the 10 betlines. The jackpot is often seen hovering around the $200,000-mark. Arabian Nights can be played for real cash at www.SlotsMillion.com.

Net Entertainment’s Cosmic Fortune – One of Net Ent’s more recent jackpot games, Cosmic Fortune was released as the first-ever five-tier progressive jackpot online slots. A five reel and 15 payline interactive video slot title based in outer-space, it boasts two bonus rounds with the chance to win one of five different jackpot totals. Spin three or more ‘Scatter’ symbols to activate the ‘free fall’ mode, where winning paylines are transformed into marbles to be used within the following ‘free falls’ bonus round. In the ‘free falls’ bonus game, marbles will drop into coin win cups or the jackpot cup – drop three marbles in the jackpot cup to activate the jackpot bonus round. In the jackpot bonus round, there are nine cups – four coin win cups an five jackpot cups. Each jackpot cup has its own prize – a rapid (fixed at $100), a mini (fixed at $500), a midi (progressive expected to pay around $4,000+), major (progressive expected to pay around $13,500+) and mega (progressive expected to pay around $100,000+). If three marbles fall into one of the jackpot cups, the total prize is yours! Attempt to win a Cosmic Fortune at www.Thrills.com.

Net Entertainment’s Mega Fortune – Having handed out the Guinness World Record for the largest-ever payout from an online slot machine game in 2013 (€17,861,813), Net Ent’s Mega Fortune is one of the most widely-played progressive slots on the Internet.

With an alluring and captivating luxurious theme, sleek visuals and fancy symbols like yachts, champagne, limousines and cigars, players will trigger the bonus round by spinning three or more ‘Bonus Wheel’ symbols across any active payline. The spinning wheel of the jackpot bonus round features three distinct sections, with the chance of winning one of the three progressive cash prizes becoming available if you land on an arrow, rather than a coin prize, within the first section of the wheel. The rapid jackpot, expected to pay out at around $500+, is won by spinning one of the two rapid symbols within the wheel’s second section. If you land on an arrow, you’ll make your way to the third section of the wheel. The major jackpot, expected to pay out at around $50,000+, is won by landing on the sole major pocket within the wheel’s third section, while if you land on the sole arrow within the third section, you’ll win the mega prize, with a projected payout of approximately $4,000,000+. Additionally, the further you progress within the wheel, the higher your prizes will be.

The man who won the record €17,861,813 did so with a €0.25 bet, so even though, as a general rule of thumb, the larger a player bets, the greater the chance of winning the progressive jackpot, you can take home the major prize with smaller wagers. Mega Fortune, our favourite online accumulative prize pool game, cn be found at Guts Casino.

BetSoft progressive jackpot slots

BetSoft’s The Glam Life – One of BetSoft’s most popular accumulative prize pool games, The Glam Life also bases its theme on the luxuries and glamours of high-style living. With three distinct bonus features and a progressive jackpot on offer if you manage to spin five ‘Yacht’ icons across any active payline, this slot title is ideal for those looking to maximise their chances at winning big. The game also boasts BetSoft’s ‘mid payline’ feature, where you can still win with a minimum of three consecutive symbols across any payline, when the first symbol does not match on the left-most reel. Join in The Glam Life at www.Guts.com.

While some of these progressive games can be played in free play mode, obviously you can only win the jackpots while playing with genuine cash. All the games and their algorithms are powered by tested and fair random number generator software.
