The number you are asking about is not on the player's screen
The payout percentage on an IGT slot machine is not a control a player can reach from the button panel, the touchscreen, or a service menu on the casino floor. It is a figure set in the game's software configuration, and changing it is a procedure that happens away from the machine, under conditions the player never sees. The question "how to change payout on IGT slot machine" is therefore not a how-to for a player; it is a question about where the setting lives and who holds the key.
This article explains the mechanism, the roles involved, and the channel through which a reader can find the current figure for a specific machine. It does not describe a procedure for altering the setting, because no player-facing procedure exists.
What the payout percentage is
The payout percentage, also called return-to-player or RTP, is a theoretical figure built into the game's mathematics. It expresses the proportion of total wagers the machine is designed to return to players over a very large number of spins. It is not a dial that moves from spin to spin, and it does not describe what any single session will do.
For a given IGT game title, the manufacturer produces multiple approved configurations. Each configuration carries its own theoretical return. The casino chooses one of those configurations when the machine is installed or reconfigured. The choice is not made by the player, and it is not made at the machine's own screen by floor staff.
Who can change the setting, and where the change happens
The change is made through the machine's internal configuration software, which is separate from the player-facing game. Access to that software is restricted. The people who hold access are typically the casino's slot operations department, working with the manufacturer's technical documentation and the jurisdiction's rules for machine changes.
In most jurisdictions, a change to a machine's theoretical payout configuration requires the machine to be taken out of service, the new configuration to be loaded, and the change to be recorded. Some jurisdictions require the change to be reported to the gaming authority or to be performed in the presence of a regulator. The exact conditions vary by state and by the class of machine, and a player cannot verify them from the floor.
Why a player cannot do it from the machine
The player-facing interface on an IGT machine offers no pathway to the payout configuration. The buttons, the touchscreen menus, and the help screens show game rules, pay tables, and denomination choices. They do not show a payout percentage setting, and they do not offer a way to edit one.
Any attempt to reach the configuration area without authorisation would involve bypassing the machine's access controls. That kind of tampering is outside the technical standard the machine was certified under, and it is handled by casino security and the gaming authority rather than by the player. The article does not describe any such method.
What a player can see on the machine
What the player can see is the pay table, which lists the winning combinations and their payouts for the selected bet. The pay table is not the same as the payout percentage. The pay table tells you what a particular winning combination pays; the payout percentage tells you the long-run theoretical return across all combinations and all outcomes.
Some jurisdictions require machines to display a theoretical return figure on the machine or in the help screens. Where that is required, the figure is shown as information, not as a control. The reader should check the machine's help screens and the jurisdiction's published rules to see whether such a display is required where they are playing.
How to find the figure for a specific machine
The authoritative current answer for a specific machine sits in two places: the casino's slot operations records and the gaming authority's filings for that jurisdiction. The player does not have access to the first, and the second is a public record in some states but not in others.
- The casino's slot operations department holds the configuration record for each machine on its floor.
- The gaming authority for the state or territory holds the approved configurations for the game title, and in some jurisdictions the record of which configuration a specific venue installed.
- The manufacturer's published game documentation lists the available theoretical return configurations for that title, but not which one a given casino chose.
For a reader who wants the figure, the practical channel is the gaming authority's public records office or the casino's guest services desk. Neither is a URL this article can supply; the reader should search for the authority by state name and the term "gaming commission" or "gaming control board".
What changes when the payout configuration changes
When a casino changes a machine's payout configuration, the visible game does not necessarily change. The symbols, the pay table, and the bonus features can stay the same while the underlying mathematics shifts. The change affects the long-run theoretical return, not the appearance of the game.
That is why a player cannot detect the change by looking at the screen. The change is in the software configuration, and the only outward sign may be a different theoretical return figure on the help screen, where the jurisdiction requires one, or a different entry in the casino's records.
What to confirm before you assume a machine's figure
Before a reader assumes they know a machine's payout percentage, they should confirm three things: whether the jurisdiction requires the figure to be displayed, whether the figure shown is for the current configuration, and whether the machine is the exact title and denomination they think it is. The same game title can exist in multiple configurations, and the figure for one machine does not transfer to another.
The channel for confirmation is the machine's own help screens first, then the gaming authority's public records, then the casino's guest services desk. None of these is a number or a URL this article can print; each is a channel the reader reaches through the venue or the authority's own site.
FAQ
Can I change the payout percentage on an IGT slot machine from the player screen?
No. The player-facing interface shows the game, the pay table, and the help screens. It has no control for the theoretical return configuration. The setting is changed through separate configuration software by authorised slot operations staff, with the machine out of service, under the jurisdiction's rules.
Where is the payout percentage displayed on an IGT machine?
Some jurisdictions require a theoretical return figure on the machine or in the help screens. Where that requirement exists, the figure is shown as information, not as a control. The reader should check the machine's help screens and the state gaming authority's rules to see whether the display is required where they are playing.
Who do I ask to find out a specific machine's payout percentage?
The casino's slot operations department holds the configuration record, and the state gaming authority holds the approved configurations for the game title. In some states the authority's records are public. The casino's guest services desk can also tell a player whether the figure is available on request.
