As online casinos continue to grow in popularity around the world, more and more players are chasing those ever-elusive monster payouts that can instantly turn ordinary people into millionaires with just one lucky spin.
But with hundreds of slots and table games to choose from, how do you know which titles provide the best odds to land a truly life-changing score? This guide breaks down the most lucrative online casino games at NineWin and some other platforms that regularly award the biggest progressive and pooled jackpots.

Slots with Millionaire-Maker Progressive Jackpots
Without question, slots dominate the online casino world when it comes to handing out seven and even eight-figure top prizes. And that’s thanks primarily to progressive jackpot networks that collectively pool small contributions from the spins of thousands of players across dozens of games to create staggering prize pools in the millions and tens of millions.
The most famous and frequently hit progressive slots include all-time classics like:
Mega Moolah
Mega Fortune
Hall of Gods
Arabian Nights
Mega Jackpots Cleopatra
Siberian Storm Mega Jackpots
These slots and other similar high variance games with rich bonus features are known for unexpectedly transforming micro-stakes players into instant millionaires. The life-changing potential of just a $0.25 spin is a big reason why progressive slots remain the most popular online casino game genre by a wide margin.
Mega Moolah in particular holds the record for the largest ever online slot jackpot - a mind-blowing €18.9 million (over $20 million) awarded to a British soldier wagering just $0.25 per spin back in 2015!
Roulette with “Must-Hit-By” Jackpots
While slots capture all the progressive jackpot headlines, some online roulette variants also include must-hit-by prize pools that guarantee big payouts when specific conditions are met.
For instance, certain rules will dictate that if the ball hasn’t landed on a particular number combination over a set period of time or number of spins, the next instance will automatically trigger the must-hit-by jackpot.
So while roulette lacks the pure life-changing scale of progressive slots, these innovative must-hit-by jackpots - which often run into the hundreds of thousands - add serious value. And they provide a fun, unique way to chase bigger payouts that you won’t find on virtual or live dealer roulette tables elsewhere.
Poker with Massive Bad Beat Jackpots
Poker enthusiasts looking to balance skill-based gameplay with some jackpot chasing excitement should consider online poker rooms with bad beat jackpot pools.
These prizes award substantial payouts when a strong poker hand loses in especially brutal fashion. For instance, sites may offer five or even six-figure prizes when four of a kind or better is beaten by an even stronger hand.
So while enduring an awful beat like losing with quads certainly stings, the jackpot payout you receive can more than make up for it. Some poker sites even pay out the prize to all players at the table.
The largest online bad beat jackpot ever reportedly awarded over $1 million to the losing player holding quad eights. And unlike progressive slots, these prizes don’t require massive individual bets to be in the running.
Lottery-Style Games and Scratchers
Online lotteries and scratch card games blend elements of slots, numbers betting and scratch tickets to deliver a compelling jackpot chasing product.
Top prizes often exceed $1 million, with some lottery games featuring pooled prizes in the tens of millions funded similarly to progressive slots. These products come packed with numerous mini games and bonus features that mimic the entertainment value of slots.
For casual players, online lotteries can be easier to understand than highly volatile slots, while still providing plenty of anticipation waiting for those balls to drop or scratch tickets to reveal a big winner.
Live Game Shows
If you prefer a more interactive, social experience, live online game shows hosted by actual human dealers are becoming increasingly popular.
These fast-paced, lottery-style titles like Deal or No Deal, Monopoly Live, Crazy Time, Mega Ball and Dream Catcher add elements of skill testing trivia, player decision-making and bonus stages to traditional numbers betting.
While top prizes generally max out at around $500,000, far below the best slots, the community atmosphere and variety of side bet payouts make online live game shows a more engaging jackpot chase for many players.
Which Online Casino Games Should You Target?
At the end of the day, no one can predict when that next million-dollar jackpot will hit. But by focusing your playtime and bankroll on the games above with proven histories of delivering monumental payouts, you give yourself the best odds of being in the right place at the right time.
Of course you can’t go wrong sticking with all-time classics like Mega Moolah or Mega Fortune either. After all, these slots hold multiple records for the biggest online jackpot payouts ever awarded.
Just realize that chasing eight and nine-figure prizes requires tremendous long-term persistence and often many years of grinding out smaller wins building up to that one epic score that changes everything.
