The National Lottery has been a staple of British culture for many years, but it's problem is that you can't play it whenever you want. The jackpot games at online casinos are an exception to this, as you can choose when you wish to search for that elusive jackpot. In addition, there are plenty more of these jackpot games to choose from, and even better, their pay-out percentages are significantly higher than that of the National Lottery.

Online casinos like Mr. Green and Maria Casino offer jackpot games. These jackpot games are generally slots, just like the ones you could find at your local convenience store, except that the jackpots are bigger and the pay-out percentages better.

Progressive jackpot games work with the principle that the jackpot grows until somebody manages to win it. This means that the jackpots often rise up to several millions of pounds, especially in Net Entertainment's most popular games. The biggest online jackpot ever won was 14 million pounds, won at Betsson's online casino!


Scandinavian game developers Net Entertainment are one of the most famous developers in the online casino business. They have created hundreds and hundreds of games for all kinds of online casinos. Their most popular games are the progressive jackpot games, where the jackpots often rise up to several million pounds.


Hall of Gods takes you to the land of Norse gods, with Odin and Thor heavily featured. The game itself has as many as 20 pay-lines, but you can't affect the amount of pay-lines in play. The minimum wager on the game is only £0.20, meaning you can chase the jackpot while only risking a couple of pennies! The maximum wager you can make is £50.

The game has three separate jackpots, of which the largest, Mega Jackpot, has risen over 5 million pounds on occasions. This jackpot can be won if you make it to the Pick Win-bonus game and find three Mega Jackpot-shields.

In addition to the bonus game, Hall of Gods also has a freespins-feature. If you acquire three scatter-symbols on any pay-line, you'll receive ten free spins. The best part of this feature is that all wins from these free spins are tripled, increasing the chance of a big win significantly!

All jackpots can be won with any bet size, meaning that you could hit the jackpot while playing with just pennies. The pay-out percentage of this game is an astounding 95.6%, huge in terms of slots! Hall of Gods is one of the best jackpot games of all time in online casinos and we can recommend it to anyone!

Hall of Gods' jackpot is usually won just after the £3-million mark, so once it's grown near that point you'll have the best chance of hitting the jackpot! £0.20 is a small price to pay when chasing millions!

Mega Fortune has a place in the Guiness book of records because of the largest online casino jackpot ever was won from the game. One lucky gambler took home a jackpot of 14 million pounds, an impressive world record!

This fantastic jackpot-game is a NetEnt creation and can be found on many a site. The game has both a bonus game and a freespins-feature. You can unlock the bonus game by getting three bonus symbols. The bonus game features a wheel, where the further you venture towards the center, the bigger your win can be. The very center is always a jackpot worth millions, but the outer levels also have wins of tens of thousands of pounds.

Three scatter-symbols unlock free spins, where the wins are also bigger. This is due to the fact that all wins from the freespins-rounds are multiplied by 1x-5x.

The game has 25 pay-lines and the minimum wager is £0.20, meaning that while barely risking any of your own money you could win millions! The game's pay-out percentage is over 96%, way better than the one offered you by the National Lottery!

Mega Fortune Dreams is the widely anticipated sequel to Mega Fortune. The game is basically Mega Fortune mark 2, meaning that the game-play is very similar, with the same bonus- and freespins-features. The graphics are the only significant change from the original Mega Fortune.

Mega Fortune Dreams offers bigger wins and its jackpot is won more frequently than that of its predecessor. Otherwise the two games are very alike.

Arabian Nights is a NetEnt slot-game that takes you to the legendary 10th-14th century Islamic world. The game features one of the largest jackpots available online, which has gone a long way in helping the game achieve the popularity it has now.

The jackpot on Arabian Nights once rose up to 6 million pounds. You can win the jackpot by getting 5 consecutive wild-symbols.

Arabian Night's pay-out percentage is 95.2%. It doesn't reach the heights of some jackpot games' pay-out percentages, like Bloodsuckers (98%), but is still better than the average percent of online slots, 95%.

Site where the Arabian Nights jackpot has been won the most times: Betsson



The Dark Knight is Microgaming's, or more accurately speaking Quickfire's creation. The game is based on the Batman-movie of the same name. It's definitely the most popular Microgaming jackpot-game and guarantees a chance to really win big. Most often this game's jackpot rises up to several million pounds. There is no pattern to how often the jackpot is won, but the larger your wager the better chances you have of winning it. This means that if you wish to go jackpot-hunting on this game, you should use as big a wager as your bankroll can afford.

Mega Moolah is an animal- and jungle-themed slot where the jackpot has risen up to 13.2 million pounds. That jackpot was won by a lucky British soldier! That kind of money must have made him think twice about serving his country on the fields of battle, but we don't blame him if he decided to lay down his weapons for a while!

Mega Moolah works perfectly well both on your mobile and browser. It has a rather popular mobile version, and is one of the oldest jackpot games of which a mobile version has even been created.
