What are progressive slot machines? Meters and Nevada's rule
A share of each bet feeds a jackpot meter that resets to a seed when hit. Standalone, local and wide-area progressives, and the rate Nevada now prints.

Progressive slot machines are slots whose top prize is a meter rather than a fixed amount. A share of every qualifying wager is added to the jackpot, which keeps rising until it is won and then resets to a seed value. The meter may belong to one machine, a bank in one casino, or a network across many venues.
That is the whole mechanism, and it is evergreen: it holds for today’s multi-prize games as much as for a single meter. What varies is the composition, from how big a share feeds the meter, how many machines share it, and what the regulator says the share must be. This piece sets the three common types side by side and adds a figure the incumbent explainers this desk read do not give: Nevada’s minimum rate of progression. On 1 November 2026 this desk read the Nevada Gaming Control Board’s published copy of Regulation 14 and CDC Gaming Reports’ account of the Board’s July 2026 workshop.
How do progressive slot machines work?
Think of the meter as a running total with three parts. There is the seed, the amount the meter starts from after each win, funded by whoever operates the jackpot. There is the increment, the percentage of each qualifying bet added to it. And there is the trigger, the event that pays it: a symbol line, a bonus round or a random award, depending on the game.
The increment is easiest to see in the worked case the Board’s technology division chief, Jeremy Eberwein, used, as CDC Gaming Reports reported it: a $1 wager on a linked progressive with a 5% increment rate raises the jackpot by 5 cents. That 5% is an illustration, not a typical or required rate. Rates are set game by game, and the paytable is the copy of record for the build in front of you, as this site’s guide to how to find RTP on a slot machine sets out.
Standalone, local and wide-area progressives compared
| Type | Who feeds the meter | Who competes for it | Nevada rule in 14.045 |
|---|---|---|---|
| Standalone | one machine’s qualifying wagers | players on that machine | not covered; the section is limited to inter-casino links |
| Local (in-house linked) | a bank of machines in one venue | players in that venue | not covered, for the same reason |
| Wide-area (inter-casino linked) | machines across several establishments | players at every linked venue | at least .1 of one percent of amounts wagered, or $100 a day for a meter that grows over time |
The wide-area row is where the size comes from. Eberwein described wide-area or multi-site progressives as products in which players at many establishments compete for one jackpot, and said the pooled liquidity is what makes the prize larger. He also said that until 2016 every wide-area progressive available in Nevada had to be confined to the state, when the regulations were amended to allow multi-jurisdictional prizes.
What is Nevada’s minimum rate of progression?
Section 14.045 of Regulation 14, in the copy headed Rev. 08/26, says an inter-casino linked system whose payoff grows as it is played must have a minimum rate of progression for the primary jackpot meter of not less than .1 of one percent of amounts wagered. The figure has a history. Per CDC Gaming Reports, the rule dates from 1999, when the Board proposed .1% and the industry asked for .4% on behalf of its customers; in the Board’s account the higher number then stood as the minimum. The section’s own history line reads “Adopted: 5/00”, so the two dates do not quite agree.
In July 2026 the Board recommended lowering the rate to .1% at a workshop, after the Association of Gaming Equipment Manufacturers (AGEM) petitioned for it, and the Nevada Gaming Commission was to consider adoption. Deputy Attorney General Mike Somps said the aim was innovation and Nevada’s competitiveness. The published copy read here prints the lower figure, and the history line for 14.045 lists an amendment dated 8/26.
Why change a rule about one meter?
Eberwein’s reasoning, as CDC reported it, is about how the format has grown. When the rule was written, a typical area-wide progressive carried one prize per game. Games now stack several wide-area prizes, or mix wide-area and local ones, and a rule that singles out one parameter for one prize does not describe the offering as a whole. It is a fair point about composition: the meter is no longer the game, only one voice in it. The site’s piece on how Hold and Spin slots work shows the same layering in the fixed-jackpot ladders studios bolt onto bonus rounds.
Progressive slot questions
How do progressive jackpots work?
Each qualifying wager adds a fixed share to a jackpot meter, so the prize grows with play until someone triggers it. The meter then pays out and drops back to a seed value set by the operator, and the climb starts again. The share, the seed and the trigger are design choices printed in the game’s rules, not constants of the format.
What is a progressive slot machine?
It is a slot whose top prize is not a fixed amount but a meter that rises as the machine, or a group of linked machines, is played. Standalone progressives grow from one machine’s wagers, local ones from a bank in one venue, and wide-area ones from machines across several venues competing for the same jackpot.
Progressive slots vs regular slots: what is the difference?
A regular slot pays every prize from a fixed paytable, so the top award reads the same on every spin. A progressive moves part of each qualifying bet into a growing jackpot, so the top award changes from one spin to the next. Some games require a particular bet level to qualify, and the paytable states which bets do.
A larger meter is a sum of other people’s stakes, not a change in anyone’s odds, and this page describes the mechanism rather than recommending play; the wider math is in how online slots work. 18+. Slots carry a built-in edge, progressives included, and the paytable governs every session.
