From celebratory lottery wins, to numerous IGT multi-millionaires, to seismic online slot wins - we take a look at the biggest betting payouts that were paid out in 2023.

€2.04 Billion ($2.6 Billion) - Biggest-Ever Lottery Winner (February)


The biggest gambling payout of 2023 was so large it broke a Guinness World Record. The lucky winner of this record breaking lottery jackpot win, an eye-watering €2.04 billion, was Californian, Edwin Castro.

Castro won the prize money from a $2 Powerball ticket, with it attached to a 29-year payment period. With significant tax deductions applied to US gambling wins, his choice to immediately cash out the win saw it reduced to a lump sum of $997.6 million.

Despite taking more than a 50% hit on his winnings, Castro is still the runaway leader on our 2023 list!

€38.5 Million - Record-Breaking Slots Win (December)


On December 20 2023, one lucky player broke the Guinness World Record for the 'Largest Jackpot Payout on an Online Slot Machine Game'. The incredible WowPot jackpot was triggered on Wheel of Wishes, with the player scooping an eye-watering €38,461,200.95 win.

The previous record jackpot payout was €19.4 million, which was won on the classic progressive jackpot slot game, Mega Moolah.

Speaking after the win, Alchemy Gaming's Chief Product Officer, Rory Harpur, said: "When we debuted Wheel of Wishes back in 2020, little did we know the incredible impact its central progressive jackpot would have."

$14 Million - Biggest Slot Machine Jackpot Payout in Reno History (April)

The biggest slot machine jackpot in Reno history was won back in April last year when a lucky player bagged themselves an incredible $14,005,832 win from just a $10 bet as they scooped the Megabucks jackpot.

The win occurred at Atlantis Casino in Las Vegas, and the news was shared in a Tweet which said: “Congrats to one of our long time Atlantis guests who turned a $10 bet into a Megabucks Jackpot of $14,005,382.09 last night! We’ve confirmed with IGT - this is the biggest slot machine jackpot in Reno History!”

$12.2 Million - Megabucks Slot Pays Out Huge in Las Vegas (October)


Whilst at Excalibur Casino in Las Vegas, and playing the IGT Megabucks Triple Red Hot 7s Spitfire Multipliers slot, an anonymous female player hit the jackpot, winning a whopping $12,185,766. This win marked the second largest Megabucks jackpot to hit in Nevada in 2023.

Lady Luck, let’s call her, wagered $10 a spin on her way to this gigantic win. This was the fourth time in 2023, in Nevada, that IGT crowned another Megabucks millionaire.

$10.5 Million - Megabucks Jackpot Lands in Las Vegas Again (July)


IGT were dropping jackpots left, right and center in 2023 - crowning Megabucks millionaires all over Nevada. Among the list was Jesus C who won a life-changing $10,488,726 off the back of $40 whilst playing IGT’s Megabucks Double Diamond Deluxe slot machine at Cannery Casino in July.

$10.1 Million - Megabucks Millionaires Everywhere (August)


A Californian visited the Aria Resort & Casino whilst in Las Vegas, and was playing $5 a spin when they landed a ridiculous win of $10.1 million. The win was achieved on the Megabucks Gold Forge slot machine by IGT.

However, the incredible part of this win was that the player only walked into the casino with $5, and put it on a single spin to win the Megabucks jackpot - which sounds like something out of a movie plot, but it was an incredible reality for this anonymous winner!

In September, a lucky patron from Dothan Alabama, Gary Thomas, won Florida Lottery's $150,000 a year for life scratch-off game. Thomas chose to take the lump sum of $2,440,000 over the $150,000 a year for life, making him a multi-millionaire.

To get the win, Thomas bought a $5 scratch-off at a liquor store near the Alabama border - and I bet he thanks himself every day for doing just that!

€2.3 Million - Player Wins The Dream Drop at Casumo (August)

Whilst playing Relax Gaming’s new progressive jackpot game, 5K Gold Mine Dream Drop at Casumo, an anonymous player landed the Dream Drop, worth a whopping €2,311,598.

What makes this win all the more remarkable is that it was triggered on a €0.60 wager and was only the player's fourth spin of their gaming session. There's lucky, and then there's that! Check out our video to see how it happened!

$690,000 - Gamblelicious Hold & Win Winning Streak at BitStarz Casino (April)


This win was Gamblelicious indeed! Back in June, a lucky player at BitStarz Casino won $690,000 on Booming Games’ Gamblelicious Hold and Win slot.

However, this wasn’t won in one go, the player called 'Joe' won this on a lucky streak, which triggered three big wins over the course of four days.

  • April 27 - won $223,786
  • April 28 - won $231,855
  • April 30 - won $239,809

While it has not been revealed how much this player was wagering on each spin, this is still a staggering run of slots luck!
