Slot Machine Payout Percentage by State (2026)

Slot Machine Payout Percentage by State (2026)

Search that question and you get a tidy table of fifty states with a percentage beside each one. Open three of those tables and the same state carries three different numbers. Nevada shows up as 93.23%, 92.89%, and 91.81% on pages that all claim to be current.

None of them are lying, exactly. They are quoting different things: one is a legal minimum, one is a fiscal year that ended six years ago, and one is a recent twelve-month window. The tables just never say which.

This page separates the two numbers that keep getting mixed together, gives every figure a reporting period and a link to the government source it came from, and says plainly where no data exists at all. That last part covers more of the country than you would expect.

Quick answer: what the numbers mean before you read them

Two different numbers get called "payout percentage"

The legal minimum is what a state's regulations require a machine to be capable of returning in theory. It is a floor, set once, and machines rarely sit anywhere near it.

The actual reported payback is what casinos really returned across every dollar players cycled through, filed with the regulator and published after the fact. This is the number that describes your session.

Putting Nevada's 75% legal floor and Iowa's 90.1% actual return in the same column, as several popular tables do, makes Iowa look four times more generous than Nevada. The reality is the opposite.

The short version

Disclosure

This site earns commission when a reader signs up with an operator through our links. That funding pays for work like parsing a 49-page state revenue report to get the numbers below. It does not influence them. Every figure here is attributed to a named government source with the window it covers, and no operator can buy a position in any table on this page.

Slots carry a negative expected return everywhere in the United States. Comparing states tells you where the cost of play is lower, not where it becomes profitable.

Legal minimum payback by state

The states that set a floor

We list only minimums we verified against the regulation itself. Where a widely repeated figure exists but we could not open the primary source, it is not in this table. That is deliberate: an unsourced number in a reference table is worse than a gap.

Why the floor tells you almost nothing

Nevada's floor is 75%. Nevada's actual statewide payback is 92.89%. The gap is nearly eighteen percentage points, and nothing in the law closes it. Competition does.

That is the whole reason a state ranking built on legal minimums is useless for choosing where to play. It would tell you Pennsylvania at 85% beats Nevada at 75%, when in practice Nevada returns more than Pennsylvania and always has. The floor only matters where it is high enough to constrain the worst machines on the floor, and in most states it is not.

Where the floor does earn its keep is at the bottom of the range. A player in New Jersey or Pennsylvania has a guarantee about the worst possible machine that a player in Nevada does not.

Actual payback: the states that publish it

Nevada, by area

Nevada publishes the deepest data in the country and the least specific. You get every area of the state broken down by denomination, and you can never see a single casino.

Twelve months from 1 June 2025 to 31 May 2026, from the Nevada Gaming Control Board monthly revenue report.

The zone detail matters more than the state average, because a visitor to Las Vegas never plays the state average. We took that apart denomination by denomination in loosest slots in Las Vegas.

Iowa, by casino

The Iowa Racing and Gaming Commission publishes payback per property. Three months ending June 2026.

Source: Iowa Racing and Gaming Commission.

Missouri, by casino

The Missouri Gaming Commission publishes a monthly detail report per property, broken out by denomination, with a total slots line. Month ended 31 May 2026.

Source: Missouri Gaming Commission. The commission notes on the report itself that these percentages represent the actual payout for a one-month period only, and that the 80% statutory minimum is calculated from standard probability rather than judged month by month.

How the reporting periods differ

This is where cross-state comparison gets slippery, so it is worth being explicit.

A single month bounces. One jackpot at a small property moves its monthly figure by a visible amount, which is exactly why Missouri prints that warning. Nevada's twelve-month column is the most stable number in this article, and Iowa's quarter sits in between. Comparing Missouri's May against Nevada's rolling year is fair for scale, not for a ranking to two decimal places.

Why most "payout by state" tables are wrong

Stale data from the pandemic year

The most cited slot payback reference in the industry still publishes fiscal year 2019 to 2020 data for most states, covering July 2019 through June 2020. That window contains months when casinos were closed entirely and months when they reopened at reduced capacity with a different customer mix. It is six years old and describes an abnormal year, yet it is the source behind a large share of the tables you will find today.

For comparison, that reference lists the Las Vegas Strip at 91.81% and downtown at 92.16%. Our current figures are 92.26% for the Strip and 91.55% downtown. The two zones have swapped places since then, which means every article repeating the older numbers has the central fact backwards.

Mixing legal minimums with actual returns

One widely ranked page lists Louisiana as "80 to 99.9%", Michigan as "min. 75%" and Nevada as "93.23%" in the same column. Those are three different kinds of number. A reader scanning that table concludes Louisiana might return 99.9%, which is a statutory ceiling nobody operates at.

Percentages with no period and no source

The same page carries an update date but attaches no window to any figure and links no regulator. A payback percentage without a period is not a fact, it is a rumour with a decimal point. Whenever you meet one, the first question is which months it covers, and the second is who filed it.

The states with no public data at all

Tribal gaming

Roughly 500 tribal casinos operate across the United States. They run under tribal sovereignty and state compacts, and those compacts generally do not require public payback reporting. Some of the largest floors in the country, including those in California, Oklahoma, Washington, and Arizona, publish nothing.

This is not a loophole. It is how the legal structure works. The practical result is that if you play in a state where tribal gaming dominates, no honest payback figure exists for your casino, and any table that gives you one is filling a gap with an assumption.

States with no commercial slots

Several states have no legal commercial slot machines at all, so there is no payback figure to publish. Others allow only limited categories such as video lottery terminals, historical horse racing machines, or electronic pull tabs, which are regulated differently and often report on a separate basis that is not comparable to a casino slot floor.

What to do when your state publishes nothing

Work from the closest published market rather than from an invented number. If you are in a tribal-heavy state, the regional casino range of 89 to 91% is a better working assumption than a state minimum, because market structure predicts payback better than law does. That pattern, and the reasoning behind it, is laid out in which casinos have the loosest slots.

From there, focus on what you can verify: the denomination in front of you, your bet size, and your session length.

Denomination matters more than your state

The Nevada ladder

Nevada, all licensees, 12 months to May 2026.

Four points separate pennies from five-dollar machines inside one state. The entire spread between Iowa's best and worst casino is 1.4 points, and the spread between Nevada and Missouri statewide is about three. The choice you make at the machine is bigger than the choice you make at the state line, which is the opposite of how this topic is usually framed. The mechanics behind that are covered in what changing denomination on a slot does.

The multi-denomination shift

Almost 70% of Nevada machines are now multi-denomination: 87,819 of 125,815 units. On those cabinets you pick the bet level on screen and the payback frequently moves with it. Any state table built on the old penny, nickel, quarter, dollar categories is describing a shrinking part of the floor. The multi-denomination line is increasingly the only one that reflects what most people actually play.

What a payout percentage costs you in dollars

Per hour by state

At 500 spins an hour and $1.50 a spin, $750 cycles through the machine each hour. Using only verified current figures:

Same bankroll, different state

Take $1,000 and play until it is gone at that pace. In Wendover it lasts about 25 hours. At the tightest verified property in Missouri it lasts about 12. Same money, same bet, same spins per hour, less than half the play time.

That is the honest case for caring about this number, and it is also the honest limit of it. Nothing here changes the direction of travel, only the speed. Run your own bet size through the RTP calculator rather than trusting our example pace, then check the swing width with the volatility calculator. Payback sets the trend; volatility decides whether you ever get to see it. If you want the same maths across table games, the house edge calculator puts them on one scale.

Land casinos against online slots

Median RTP across 3,674 games

Our RTP database holds 3,764 entries from 15 providers, of which 3,674 are slots, collected from provider certification data and frozen on 27 July 2026.

Only 39 of those 3,674 online games publish an RTP below 94%, which would place them near the bottom of the land market range. The structural reason is straightforward: a server does not need a building, a floor staff, or a location.

The same game at five certified RTPs

The comparison has a catch most sites leave out. In our data, 313 slots ship in more than one certified configuration, with a median spread of 3.5 points. Starburst is a fixed 96.08%, but plenty of famous titles are not. Fire Joker is certified at 84.26%, 87.24%, 91.23%, 94.23%, and 96.15%, and the operator picks which build to run.

So "online pays more" holds only if you check the version. Per-game pages such as Starburst RTP list what is certified, the highest RTP slots ranking narrows the field, and the methodology sits on our RTP database. The interaction between return and swing size is worth reading before you use any of it, and that is covered in RTP vs volatility.

How to check the number for your own state

Where to look

Go to your state gaming commission or control board website and look for revenue reports, statistics, or publications. Three patterns turn up.

Some regulators publish a payback column directly, like Iowa and Missouri. Read it and you are done.

Some publish handle and win without a payback column, which is most of them. Divide win by handle, subtract from 100, and you have the payback for that period.

Some publish revenue only, with no handle at all. In that case payback cannot be derived, and any figure circulating for your state was estimated by somebody.

What to ignore

Ignore any table without periods. Ignore any figure attached to a tribal property. Ignore legal minimums presented as expected returns. Treat single-month property figures as noisy, exactly as Missouri's own regulator asks you to.

One practical footnote that catches people out: a good payback percentage does not change how a big win is taxed. If you are planning around a jackpot rather than a session, the gambling tax calculator and our guide to where offshore play stands legally matter more to your net than a point of payback does.

The verdict

There is no single slot payout percentage for a state, and the tables that pretend otherwise are usually blending a legal floor with a stale actual return.

What we can verify right now: Nevada returned 92.89% statewide over the 12 months to May 2026, with a range from 91.55% downtown to 94.74% in Wendover. Iowa's 19 casinos ran 89.3 to 90.7% over the quarter to June 2026. Missouri's 12 ran 88.87 to 90.76% in May 2026. Legal minimums we could confirm span 75% in Nevada to 85% in Pennsylvania, and none of them describe a real machine.

Everything else is either unpublished, tribal, or an estimate wearing a decimal point. Judge any payout-by-state table by one test: does every number carry a period and a source you can open. Most fail it, and now you have the version that does not.
