The Biggest Online Jackpot Wins Ever Recorded

Online progressive jackpots have produced some astonishing wins — sums that would make headlines in any lottery. Here are some of the biggest publicly reported ones, all from networked progressive slots. Amounts are shown in the currency they were paid in; exchange rates make a strict ranking across euros, pounds and dollars impossible, and new records are set from time to time.

The Mega Moolah network has paid eight-figure sums many times. Note the difference between a jackpot that was won and a pot on offer: Games Global's WowPot pool passed €40 million in 2023, but an advertised pot isn't a payout until someone wins it. For the story of the game behind most of these records, read Mega Moolah: the millionaire maker.

What these wins have in common

• Networked jackpots. Every record above came from a progressive linked across many casinos, so the pool grows quickly.
• Small bets. Several record winners were staking a pound or two per spin — the DraftKings record came from a 20¢ spin.
• Random triggers. Most modern jackpots are triggered by a random bonus wheel, not by a specific symbol line.

The odds behind the headlines

The odds of hitting a top-tier progressive on any given spin are tiny — often in the tens of millions to one, depending on the game and bet. Funding those prizes is why jackpot slots usually have a lower base RTP: most players pay a little extra on every spin for the chance that someone, somewhere, wins big.

What happens when you win a jackpot

2. Your identity is checked again, even if you're already verified.
3. Payment. Network jackpots such as Mega Moolah are usually paid in full; some casino terms allow very large wins to be paid in instalments, so read the jackpot rules first.
4. Tax depends on where you live:
