Progressive Jackpot Casinos 2026: Mega Moolah and WowPot

The jackpot meter for Mega Moolah is the same at every casino it is offered at, but the terms and conditions aren't. Some casinos pay their jackpots as one lump sum, while others pay them out in instalments. Here are 4 casinos that offer the biggest jackpot networks, ranked in order from best to worst in terms of how safely a jackpot is paid out.

Progressive jackpot games at these casinos

The majority of the large jackpots are in a few networks. One network is shared among all casinos that host the game, therefore the jackpot amount is the same at all of those casinos. The rules and regulations associated with that game vary among casinos that host the same game.

The Mega Moolah amount is the same across all casinos, and at the time of writing was shown as $14,870,900 at Jackpot City, $14,872,265 at Grand Mondial, and $14,875,016 at 7Bit Casino. The slight differences are in the meter while playing the game, and the WowPot figure is the Wheel of Wishes meter from Jackpot City's winners page.

Game lists vary by country because certain studios withdraw their games in certain regions. The numbers from 7Bit are from connections in Canada (September), and Norway (October). Before depositing, make sure the game you want to play is in the lobby.

The four progressive jackpot casinos up close

In the same order as the list at the top. Each picture is from the casino’s site, and shows what the corresponding text describes.

Jackpot City logo

1. Jackpot City: both giant meters, and jackpot wins skip the caps

Jackpot City Mega Moolah and Wheel of Wishes progressive jackpot meters
The two jackpot meters on Jackpot City's winners page, 1 October 2026.

No other casino we’ve covered has as many Mega Moolah games as Jackpot City. With three Mega Moolah live blackjack games in August, Jackpot City’s Canadian lobby had a total of 28 games in that month. Add 8 WowPot games, the King Millions family and 129 Lotsaloot “must-win” games and the total is 192 jackpot games.

The most important part of the terms is where they defend limiting the biggest winners to £4,000 per week and cap bonus winnings at 6x the first deposit. Both end with “All progressive wins are exempt.” There is a daily withdrawal limit of £10,000 with no such line, so support should be emailed to ask how a big jackpot would be paid.

The weakest part of Jackpot City is proof. The winners page has two meters and an unnamed feed of small wins. There is not a single dated million-dollar win on the site for a casino that has been operating since 1998.

  • 28 Mega Moolah games, the most we've seen
  • Progressive wins exempt from the weekly and bonus caps
  • Kahnawake licence, owned by NYSE-listed Super Group
  • No named or dated big winners on its own site
  • 101 blocked places
  • Jackpot games count 0% toward the welcome bonus

2. Spin Casino: $20.1 million in jackpots on one page

Spin Casino progressive jackpots page with a $20,100,950 jackpot total
The jackpot total on Spin Casino's progressive jackpots page, 1 October 2026.

Spin Casino is Jackpot City’s twin. The two casinos have the same owners, same license and same 192 jackpot games. Spin Casino’s jackpot page shows a total of $20,100,950 on 1 October 2026.

Most of that total is the shared Mega Moolah pool, so it says little about Spin itself. The useful part is the same as at Jackpot City: "All progressive wins are exempt" from the £4,000 weekly clause and from the 6x bonus cap.

Spin lists “oodles” of jackpot winners but fails to name a single one. The only dated win record on its page is from 2015 with Mega Moolah at Betway, a sister brand. Welcome bonus is smaller than Jackpot City, at $1,000 over 3 deposits at 35x.

  • Same 192 jackpot games as Jackpot City
  • Jackpot wins exempt from the payout caps
  • 35x wagering, light for this kind of casino
  • "Oodles" of winners, none named
  • GBP 10,000 daily limit has no jackpot line
  • Same 101 blocked places as Jackpot City

3. 7Bit: Mega Moolah in crypto, paid in full outside the cap

Mega Moolah progressive jackpot game on 7Bit with the meter at 14,875,016.06
Mega Moolah on 7Bit from a Norwegian connection, 1 October 2026. The top meter was last won a year ago.

7Bit is a Mega Moolah host with a crypto option. The meter showed the top prize at 14,875,016.06 and the last win on Major was three days prior. From a Canadian connection in September, their lobby listed 13 Mega Moolahs, 7 WowPot games and 21 Age of the Gods.

Their terms allow unlimited progressive jackpot payouts. Withdrawals are limited to 0.12 BTC a week and 0.48 BTC a month, but 11.8 states “Progressive jackpot wins are paid in full and do not count toward these limits.”

Bonus money and free spins cannot be used on progressive jackpot games, meaning their large welcome bonus is no good. Where you are determines what licence 7Bit has, so it’s harder to pin down than the Kahnawake casinos.

  • Progressive jackpots paid in full, outside the caps
  • Mega Moolah, WowPot and Playtech jackpots in one lobby
  • Crypto deposits and withdrawals
  • Non-jackpot wins wait at 0.12 BTC a week
  • Bonus money can't touch jackpot slots
  • Licence and owner change with your location

4. Grand Mondial: five Mega Moolah tiles, seven named millionaires

Grand Mondial Mega Moolah progressive jackpot meters, five games sharing one pool
Five jackpot tiles, one shared Mega Moolah meter. Grand Mondial's games page, 1 October 2026.

Grand Mondial names its jackpot winners and lists seven on Casino Rewards from 2017-2024, with the largest being CA$5,748,072.67 from Immortal Romance Mega Moolah (Sept 2022). Another player won $5,691,921.42 from a 25 cent bet in 2018.

Its games page is forthright regarding the pool. Five Mega Moolah games are behind a single meter, and the page combines them as $14.9 million instead of counting the same pool five times.

The risk is in the terms. Big winners can be paid $4,000 a week, and that clause makes no exception for jackpots. The group’s Winners page says the millionaires were paid, but the terms themselves don’t guarantee a lump sum. The 200x bonus is best avoided.

  • Seven named, dated Mega Moolah millionaires
  • Honest jackpot meters on its games page
  • Kahnawake licence since 2010
  • $4,000 weekly clause with no jackpot exception
  • 200x wagering on the welcome offer
  • No published list of blocked countries

Notice the stakes. €15 and €20 bets, a 25c spin at Grand Mondial in 2018. Small bets can win the top prize, and that's the whole premise. The full list, with streamer wins next to the jackpots, is on our biggest casino wins page. Every sourced jackpot is listed on Mega Moolah winners and WowPot winners. On Mega Moolah, a larger bet increases the chance of reaching the jackpot wheel, but it never guarantees a spin on the wheel. Our biggest casino wins list puts these hits next to land-based casino records.

How a progressive jackpot works, step by step

The same idea applies to every network. The information below applies to Mega Moolah, the most famous of them all.

  1. A slice of every bet feeds the pool

    Instead of contributing to the base game, a small percentage of each spin contributes to the jackpot. That is why the pools grow even just a little with every spin, at every casino on the network.

  2. The jackpot wheel decides the tier

    On Mega Moolah, the bonus wheel has four prizes. The biggest is the Mega jackpot. On the 7Bit screen capture, the Major was won 3 days prior, and the Mega was won a year prior.

  3. The casino pays it out

    Studios like Games Global announce the big hits themselves. The casino pays the win into your account after its usual identity and source-of-funds checks.

  4. The meter starts again

    After a hit, the pool resets to a starting amount. Because of the reset, meters can vary widely from one year to the next.

There are two other jackpots in the lobby. Games Global’s Lotsaloot jackpot is a “must-win” jackpot, meaning it will drop and award the jackpot before it reaches a set amount, so the jackpots are smaller, but happen more frequently. A local jackpot is fed by players from one casino only, so they will also never award the larger, eight-figure jackpots. Seeds, tiers and the RTP trade-off are explained in how progressive jackpots work.

What progressive jackpot games cost you in RTP

The pool has to come from somewhere. It comes from the base game’s return to player (RTP), which is lower on the bigger jackpots.

  1. Mega Moolah86% RTP setting
  2. Mega Moolah88% listed at Stake
  3. Lotsaloot92% RTP setting
  4. King Millions96% on a few titles

RTP settings in Jackpot City's lobby data (August 2026) and the figure on Stake's Mega Moolah page (1 October 2026). Bars start at 80% so the gaps show.

The classic Mega Moolah games had an RTP of 86% in Jackpot City's lobby data, the lowest of all 192 jackpot games there. A normal slot games runs around 96%. Over a long session, $100 on the classic Mega Moolah gives back about $10 less than a normal slot.

That’s the trade. You pay for a small chance at a life-changing prize. Play Mega Moolah for the jackpot with a budget you’d spend on a lottery ticket, and play other games for longer sessions.

A check means the terms don't block you. It doesn't make online gambling legal where you live so be sure to check your local laws. Jackpot City and Spin share a list of 101, and 7Bit has 50.

It breaks the terms of all four casinos to use a VPN to get around a block, and with a jackpot on the line that's the worst way to lose one. The full lists are in each of the reviews: Jackpot City, Spin Casino, 7Bit, and Grand Mondial.

How we ranked these progressive jackpot casinos

The scores that follow rate each casino for a single job; being the casino you chase a progressive jackpot. There are four factors that determine the scores.

  • 35%

    Paid in full

    If the terms and conditions exclude progressive jackpot winnings from the weekly, monthly, and/or bonus caps.

  • 25%

    Jackpot range

    How many network progressives does the lobby carry and from how many game/software studios.

  • 20%

    Proof of winners

    Does the casino name dated winners, or does it only show meters and anonymous feeds?

  • 20%

    Who can join

    The shorter the blocked list, the more readers can actually play.

Jackpot City leads on range and on the written exemption. Spin matches it on both but offers less around them. 7Bit pays jackpots in full and carries more studios, but its bonus can't touch them and its licence shifts by country. Grand Mondial has the best proof and the weakest terms. Overall scores live in each review, and our review method explains them.

Progressive jackpot casinos FAQ

Which online casino has the most progressive jackpots?

Of the casinos we reviewed, Jackpot City and Spin Casino offer 192 jackpot games, of which 28 are Mega Moolah games. 7Bit has fewer Mega Moolah games and adds Playtech’s Age of the Gods games. See the Jackpot Games table.

Is the Mega Moolah jackpot the same at every casino?

Yes. The Mega pool is shared among all the casinos on the network. As of October 1, 2026, it was approximately $14.87 million at Jackpot City, Grand Mondial and 7Bit, which differed slightly as it increased between visits.

Do casinos pay progressive jackpots in full?

It depends on the terms. Jackpot City and Spin Casino exempt progressive wins from their weekly and bonus caps, and 7Bit pays them in full outside its 0.12 BTC weekly limit. Grand Mondial’s $4,000 weekly limit does not exclude jackpots. More in paid in full.

Can I use a welcome bonus on progressive jackpot slots?

Usually not in a helpful way. Jackpot games count 0% toward wagering at Jackpot City and Spin Casino. At 7Bit, bonus funds and free spins cannot be used on progressive jackpots. Play Jackpots with your own funds.

Do progressive jackpot slots have a lower RTP?

Yes. On jackpot games, a small percentage of each bet contributes to the progressive jackpot. Thus the base game pays back less. At Jackpot City, the Mega Moolah game was set at 86%, while the average for normal games was about 96% (lobby data). See the RTP cost.

Play it safe

Gambling is for adults only (18+, or older where local law says so). Treat every deposit as money spent on entertainment, never as a way to make money. If it stops being fun, take a break with the casino's own tools or talk to Gambling Therapy, which offers free support in many languages.
