While some players have seen large progressive jackpots accumulate in the past, these can occasionally creep up to numbers in excess of $10 million. In this article, we look at the biggest wins of all time from some of the most popular online slots. Keep in mind that this list is based on the winnings in dollars, based on the conversion rate at the time. 

A $24 million hit takes the top spot on our list of big slot wins. This was awarded on the slot Mega Fortune, with the Finnish player spinning with a stake size of $0.25. He was awarded with the progressive jackpot that is available to all players, regardless of the bet.  

The second largest win on an online slot machine occurred in 2021, as a player from Belgium was awarded with €19.4 million. At the time, this translated to over $23.6 million. As for the slot itself, it was created by Triple Edge Studios and has awarded billions of dollars collectively since it was released in early 2020. 

This $23.5 million jackpot was awarded to an anonymous individual at the Grand Mondial, a UK-based online casino. It was hit with a bet size of $0.75, and according to the winner, less than 50 spins were played out. When it comes to winning big on slots, this hit is up there with the best!

There are two hugely interesting aspects to this slot big win. First, it was streamed live to thousands of people around the world, and second, the $21 million wasn't from a jackpot. Tyler Niknam, also known as 'trainwreckstv' was the lucky punter, with footage of the hit being available on YouTube. 

Not only is this player a resident of the United Kingdom, but he is also a soldier, which perhaps makes this hit even more fulfilling to bystanders. Jonathon Heywood was awarded with roughly $19.9 million when playing at 0.25 per spin. The story gets better, too, as Jonathon claimed he would use a portion of his winnings to look after his unwell father. 

Arabian Knights by NetEnt is a prime example of a retro online slot. It features 5 reels, 3 rows, and 10 paylines, all of which are displayed on either side of the board. In 2011, the associated progressive jackpot for this game reached $17.3 million, at which point it was awarded to a Norwegian player. 

At number seven, Mega Moolah makes another appearance. However, this will not be its last. Again, this $10 million spin was a result of the progressive jackpot being awarded to Rawiri Pou in 2016. The 27-year-old Rawiri said he wanted to treat his family with some of the winnings. 

Hall of Gods is another NetEnt slot on our list of big casino wins. It comes with their signature user interface, which mimics a traditional arcade slot machine. We know absolutely nothing about the player that was awarded the mega jackpot, as they remained completely anonymous. However, we can safely say that the slot big win occurred on the 18th of April, 2015. 

John Orchard is yet another player on this list that was keen to spend the majority of the winnings on his family. Before winning £5.9 million with a bet size of 30p, John said he was initially planning on buying his daughter an iPad as a gift. After the jackpot hit, however, he decided to buy her a house instead! 

What better way to round off this list, than with another massive win on Mega Moolah? This time, a $0.50 stake was used, with the progressive jackpot being triggered to award a total of $5.5 million. According to the provider, Microgaming, this was the 13th win that totalled over $1 million across all of their releases. Klaus is now one of many slots big winners to strike it lucky on Mega Moolah!

When it comes to being awarded with potential winnings on any slot, it all relies on luck. There is no strategy that can help players increase their chances of a successful spin. 

While anyone can win big on online slots, the odds are stacked heavily against the player. This is particularly true with progressive jackpot slots, as thousands of other punters may also be spinning at the same time. 

No, there is no trick when it comes to big slot wins. The outcome of each spin is determined by a random number generator, which cannot be influenced in any way. 

Some slots can award more back to players over the course of millions of spins. This is referred to as RTP or return to player. For example, if the RTP of a slot is 95%, then 0.95 for every 1.00 wagered will be redistributed to punters. 

No, online slots do not remember players. This debunks the myth about certain slots being 'due' if they haven't awarded any potential winnings in a while. Big slot wins are awarded totally at random.
