About this project
This is an educational reference about progressive jackpots: how a pool is funded by a slice of every qualifying stake, how it is seeded, how a drop rule bounds it and how a win resets it. It exists to describe a mechanism clearly, not to sell a game or to help anyone bet one.
Meter 01What this site is
This site explains the structure of a progressive jackpot. It covers the contribution that funds the meter, the seed that starts it, the qualifying stake that governs eligibility, the drop rule that bounds the pool and the reset that follows a win. It is written to be read with an operator's terms open beside it, so that the terms make sense rather than being skimmed.
It is one of a series of reference sites, each about a single subject in how gambling products work. Like the others, it is deliberately descriptive: it explains what a mechanism is made of rather than telling anyone what to do with it.
- How a pool is built
- Where the money comes from
- How a pool is bounded
- What decides a payout
- What a meter really costs
Meter 02What this site is not
The boundaries matter as much as the content. This site does not rank games, does not name an operator, does not suggest a stake and does not predict the trigger. It does not tell you whether progressive products may be offered where you live, and it does not tell you what is owed on a prize in your own jurisdiction. It describes a mechanism; it does not advise on your position or your eligibility.
| This site does | This site does not |
|---|---|
| Explain how a progressive pool is funded and bounded. | Recommend a game, a stake or a provider. |
| Describe the rules that decide eligibility. | Assess your own eligibility or jurisdiction. |
| Show how the arithmetic of a contribution behaves. | Promise or predict an outcome. |
| Point to responsible-gambling support routes. | Offer legal, financial or tax advice. |
Meter 03How the pages fit together
The pages follow the life of a pool. The pool introduces the inflow, the bound and the trigger. Contribution shows where the money comes from and what one stake costs. Seeding explains the starting figure. Must-drop covers the ceiling. Reset explains why the meter drops. Networked compares local and shared pools, eligibility covers the rules that decide a payout, how to read one is the checklist and false beliefs collects the common misreadings.
A note on sources
Explanations here describe mechanisms that are documented in operator terms and in the published rules of the games themselves. Where a number is given as an example, it is labelled illustrative: the actual rate, stake or ceiling of any game is set by its own rules, not by this site.
Meter 04If gambling is causing harm
This site is for adults, and it treats the risk of loss as a fact to be described rather than a caveat to be buried. If gambling is causing financial harm, or is affecting your relationships, your sleep or your mental health, free and confidential support is available in most countries through national gambling-harm helplines, for players and for the people around them. Setting deposit limits, session timers or self-exclusion before you play is far easier than trying to stop in the middle of a session.

The clearest single explanation of what a progressive is: a container fed by a slice of every qualifying stake, bounded by a rule and emptied by a rare win.
Affiliate disclosure and risk warning
Every affiliate link on this page and in the header is a sponsored link to a partner operator, and we may be paid if you open an account through it, at no extra cost to you. That link pays us; it does not make a jackpot more likely to land, it does not improve any decision, and it is never a recommendation to play. Nothing on this page is legal, financial or betting advice. 18+ only. Gambling is a real risk of real loss. A progressive jackpot is the clearest case there is of a prize that feels like a windfall and is in fact a funding mechanism: the meter is other players' money, collected a fraction of a stake at a time; the road that leads to it is the game itself, whose house edge is applied to every stake whether or not the meter ever climbs; and the event that pays it is rare, deliberately weighted, and usually open only to the maximum stake. The average player is behind before a single spin, and a larger prospective prize does not change the arithmetic of the game that funds it. Whether these products may be offered where you are, who may play, whether the operator is licensed, what is owed on winnings and whether any form is lawful all differ between countries, states and provinces, and they change; a general explanation of how a meter is built is not advice on your own position or your own eligibility. Never stake money you cannot afford to lose, never borrow to play, and never chase losses with a larger stake. Chasing a growing meter with bigger stakes is the single most expensive habit this subject invites. Gambling can cause serious financial harm, including debt and damage to relationships and mental health. Free and confidential support is available in most countries through national gambling-harm helplines, for players and for the people around them.
