A regular slot pays from a fixed table: the biggest possible win is a set multiple of your stake. A progressive jackpot slot adds a prize pool on top that keeps rising until someone wins it. A small slice of every eligible bet feeds the pool, so the longer it goes unclaimed, the bigger it gets. At Jackpot City, the most popular pools are shared across many casinos at once, which is how they can climb into seven or even eight figures.
How progressive jackpots work
Networked vs. local pools
Networked (or "wide-area") jackpots link the same game across many online casinos run by different operators. Because thousands of players contribute, these pools grow quickly and reach the biggest totals — Mega Moolah is the classic example. Local or in-house jackpots are fed only by players at one casino or one operator group, so they're smaller but can be won more often.
Jackpot tiers
Most modern progressives have several tiers rather than one prize. A common structure is four levels, often called Mini, Minor, Major and Mega (or Grand). The lower tiers reset at modest amounts and drop frequently; the top tier is the life-changing one and can go months between wins.
| Tier | Typical size | How often it drops |
|---|---|---|
| Mini | Tens of dollars | Very often |
| Minor | Hundreds of dollars | Regularly |
| Major | Thousands to tens of thousands | Occasionally |
| Mega / Grand | Often C$1 million or more on big networks | Rarely |
Figures are illustrative; seed values and pool sizes differ by game and change constantly. The live amounts are shown in the lobby and inside each game.
How a jackpot is triggered
On many games the jackpot is decided by a separate random event — often a bonus wheel or a pick game — that can trigger on any spin. On several networks your chance of reaching that bonus rises with your stake, though even a minimum bet can win the top prize. Each game's rules panel explains exactly how its jackpot is awarded.
Jackpot networks at Jackpot City
Reviews in 2026 count more than 50 progressive slots at Jackpot City, almost all supplied through Games Global. These are the names you'll see most:
Mega Moolah
The safari-themed slot that made online progressive jackpots famous. Its four-tier jackpot wheel can trigger on any spin, and the top tier is seeded at seven figures. Mega Moolah has produced multi-million-dollar winners around the world, including players in Canada, and it now has several spin-off versions sharing the same pools.
WowPot
A newer Games Global network built to grow very large, with titles linked to a shared multi-tier pool. Like Mega Moolah, it's a long-shot prize sitting on top of an ordinary slot.
Wheel of Wishes
A fairy-tale themed slot with its own wheel-based jackpot feature and several tiers. It's frequently mentioned alongside Mega Moolah as one of the jackpots that pushes pooled prizes past the C$5 million mark.
King Millions and other pools
King Millions and a rotating set of smaller progressives round out the section. The selection changes over time, and the Ontario and Alberta sites may list different titles from the rest-of-Canada site.
Wolf Gold isn't a progressive, but its three fixed jackpots make it a lower-risk way to try jackpot-style gameplay. For more non-progressive options, see our Jackpot City slots guide.
The Mega Millionaire Wheel
Separate from the jackpot slots, Jackpot City runs a daily prize wheel for players who have made a deposit. You get ten free spins on the Mega Millionaire Wheel every day, and the top prize is C$1,000,000. Most spins land on small prizes such as free spins or bonus credit, or on nothing at all — but they cost nothing to use.
The million isn't just marketing copy. According to gambling.com, a player from northern British Columbia won C$1,000,000 on the wheel on January 12, 2025. Prizes from the wheel usually come with their own terms, so read them in your account before you play through any winnings. The Jackpot City bonus guide covers how the wheel fits in with the welcome offer.

Go to Jackpot CityWhat are the real odds?
It's worth being blunt here: the chance of winning a top-tier progressive on any given spin is extremely small. Studios don't publish exact odds, but the maths of a seven-figure prize funded by small bets means most players will never hit the top tier. The lower tiers drop far more often and are a more realistic target.
Lower base-game returns
Part of every bet on a progressive funds the jackpot, so the base game usually has a lower RTP than a typical non-jackpot slot. In other words, you pay for the chance at the big prize through smaller everyday returns. That's a fair trade only if the jackpot is what you're really playing for.
Jackpots and bonus wagering
Progressive jackpot games count 0% towards the welcome bonus's 35x wagering. If you spin Mega Moolah with bonus funds, you'll use up your balance without making any progress towards a withdrawal. Many players clear the bonus on standard slots first and switch to jackpots afterwards, or skip the bonus entirely when they only want to play progressives.

What happens if you win big
Large jackpot wins go through extra checks before payment, including verification of your identity and sometimes the source of your funds. Big prizes may be paid in instalments or under specific terms set by the jackpot provider and the casino, so read the game rules and the casino's terms for how wins above certain thresholds are handled.
Do you pay tax on casino winnings in Canada?
For most people, no. In Canada, gambling winnings of recreational players are generally treated as windfalls and aren't taxable. The situation can be different if gambling is considered a business or a professional activity, and any interest you earn after investing a win is taxable as usual. This is general information, not tax advice — speak to an accountant if you land a large prize.
Our take on Jackpot City's jackpots
Few casinos available to Canadians can match the depth of Jackpot City's progressive lineup, led by Mega Moolah, WowPot and Wheel of Wishes, plus a free daily shot at C$1M on the Mega Millionaire Wheel. Play them for the dream, budget for the reality, and keep them separate from your bonus play.
