We look at nine casinos, eight registered accounts and one method. We photograph their lobbies, pull the game feeds from their platforms, type deposit amounts into their cashiers and read their bonus clauses, then track the progressive pools they offer. This page is the door to all of it.
There are three progressive networks in the market for casino games and they all share the same progressive game counter between all of the casinos that offer the specific game. These counters are logged in the registered casino accounts from which the data is collected, on dates we print next to every number.

Stood at $2,256,953 by our next read, a climb of $4,435 between the two checks.
Counters move constantly; the figures above animate from the values we logged and keep climbing at roughly the pace we observed. The dated reading is the fact, the motion is an estimate. Full pool histories sit on each ranking page.
All of the data on this site comes from registered casino accounts. We take photographs of the lobbies. We log into the accounts and type amounts into the cashier to find the real deposit floors. We calculate the bonuses from the published terms and conditions for each casino. The three below lead the table. The other six, including the low scores for the casinos, are featured in the full review index.
The most complete jackpot shelf in the market, including all 28 titles of Mega Moolah, the full eight of WowPot and the deepest lobby of all the listed sites, with a published payout window to go with it. The Jackpot City review shows the screenshots behind every number.
Spin Casino's lobby is identical to Jackpot City's: our Spin Casino review machine-compared the two and found zero differences, jackpots included. Spin has 16 crypto coins beside Interac, and a lighter three-deposit ladder.
Royal Vegas offers the same 2,001 games behind a C$1,200 deposit ladder in four equal C$300 rungs. The Royal Vegas review covers the one real difference between these sites: a doubled Interac floor at C$10.
Strip the branding away and the nine casinos we review resolve into two platforms. Knowing which door leads to which room is most of the game.
Baytree Interactive operates four brands on one platform: Jackpot City, Spin, Royal Vegas and Ruby Fortune. Each brand includes 2,001 games, 192 of them jackpot titles, and offers 35x wagering on every offer. All games have the same payout settings. Our sister-sites guide proves this tile by tile.
Casino Rewards operates four brands on one platform: Zodiac, Casino Classic, Grand Mondial and Yukon Gold, plus the loyalty programme that connects them. Each site includes 1,582 games, the famous low-deposit offers and the King Millions jackpot. The group guide weighs all four doors.
| What we measured | Baytree Interactive | Casino Rewards |
|---|---|---|
| The brands | Jackpot City, Spin, Royal Vegas, Ruby Fortune | Zodiac, Casino Classic, Grand Mondial, Yukon Gold |
| Games per lobby | 2,001 | 1,582 |
| Jackpot shelf | 192 titles, including all 28 Mega Moolah | King Millions' 27 games, 5 Mega Moolah titles |
| Wagering | 35x | 200x on the first two deposits |
| Deposit floor | C$5-C$10 by Interac | $1 at Zodiac, with the catch we document |
| Weekly payout cap | Progressive wins exempt | $4,000 |
Each ranking page takes one slice of the market and prices it from the account evidence.
Eight doors sell the same $13M pool. What differs is titles, cost and terms.

The Guinness World Records entry for the largest online slot payout still belongs to Mega Moolah. The slot paid out €17,879,645 on October 6, 2015, which translates to $20,062,600 according to Guinness. We checked the record page on August 7, 2026 and the entry still stands.
The casinos add their own claims. The homepage of Grand Mondial has for years featured a winner's cheque for $1,413,537.73 dated November 15, 2017, and its rotating testimonial cites a $11,610,536.59 Mega Moolah win. These are operator statements on operator pages. Worth reading, worth weighing.
Every verified payout we could document is represented in the Mega Moolah winners list. A detailed explanation of how the nine-figure counter builds back up after a win is in how progressive jackpots work.
Fourteen support guides carry the research on which the rankings are built. All of these guides are built from the same account evidence and named sources.
One reviewer works the accounts, eight of them registered from Calgary, under a rule with no exceptions: if a casino refuses our connection, it gets no score. LeoVegas currently refuses every province except Ontario, so its page carries no button to visit the casino. For the complete method used in the rankings, see how we review.
Dean opened and maintains the research accounts behind every review on this site: lobbies photographed, cashiers tested, terms read in full, pools logged on dated checks. What he found at each casino is on his author page.
The largest of all the pools that we track belongs to Mega Moolah, which read $13,016,431 in the Jackpot City lobby on August 5, 2026 and climbed continuously that week. WowPot read $2,252,518 and King Millions read $2,342,878 the same week. All casinos that feature these games show the same shared jackpot counter for those pools, so no site displays a larger version of the same jackpot.
Jackpot City features the highest score in our reviews at 4.2 out of 5, based on 28 titles for Mega Moolah, a minimum deposit of C$5 with Interac, and a published 1-3 day withdrawal time. Spin Casino and Royal Vegas score 4.1 and 4.0 respectively, on the same platform but with different offers. All nine casinos, with their highest and lowest scores, are displayed on our casino reviews page.
Partly. Zodiac Casino will accept your $1 deposit into its cashier and features four different variants of Mega Moolah in its lobby, but the advertised 80 chances are spins on Mega Money Wheel, a different game, at $0.10 per spin. At the Baytree brands such as Jackpot City, the practical floor is the C$5 Interac minimum. This guide to the $1 deposit breaks down the offer for you clause by clause.
For recreational players, no. According to the Canada Revenue Agency, gambling winnings are an amount that is neither reported nor taxed, and Income Tax Folio S3-F9-C1 states that gambling wins are considered windfalls. However, the interest earned on those winnings is taxable, as is the gambling income of professional gamblers. Both of these exceptions are quoted in our withdrawals and taxes guide.
These are international casinos that accept Canadian players, and most hold a permit from the Kahnawake Gaming Commission, which we verified on the regulator's own register. Ontario has its own licensing authority for casinos. LeoVegas is the only casino we cover that is licensed there, and it keeps itself separate from the other provinces. Find out more about the gambling laws in each province in Canada.
A progressive jackpot is a kind of lottery that is priced per spin. These games offer some of the lowest payback percentages in any casino lobby: the flagship Mega Moolah pays back 88% by design. Set a deposit limit before you play and treat each spin as entertainment with a price. For the limit tools we found at each casino and the free help lines in every province, see our responsible gambling page.

Progressive spins weight 0% toward the welcome bonus here. A jackpot chase and the C$1,600 offer are two separate budgets.
