Slot Check, Inc., is an independently owned and operated company with no ownership interest from any casino or its owners.

Slot Check was founded in 2020 by professor and entrepreneur, Grant Stousland. Before creating Slot Check and making slot transparency his mission, Mr. Stousland made history in the casino gaming industry with Gaming Informatics (GI). GI brought to market IRIS® – a first-in-class Integrated Regulatory Information System for casinos and casino regulators in the United States.  Today, IRIS® by Kobetron®, continues to work behind the scenes to help ensure that the slot machines you play comply with tribal, state, and federal regulations. In doing so, it helps to ensure fair play for the consumer.

It is no surprise that it took an innovator to embark on the audacious goal of creating a technology company that shares real-time slot performance data with players. Slot Check and its affiliate casino provide players with the Hot Slot Insights they have wanted since the invention of the slot machine in 1894.

Players, the public, investors, and gaming industry veterans often ask us, “Why are casinos sharing access to their slot data? What incentive do they have to share their slot data with the players?”

The answer is straightforward: Player Loyalty.

Player Loyalty:

When Slot Check was being developed, our player focus groups were asked many questions. One of those questions was, “If you have three casinos to choose from, and one is on the Slot Check app, which will you go to first?” 100% said they would go to the Slot Check casino first.

Being a Slot Check Affiliate Casino means more new customers. Regular customers will visit and play more. Slot Check means more entertainment value to players and more revenue for casinos. It is no surprise that what is good for players is good for casinos. When players win, casinos win.

Slot Check receives its data, by agreement, directly from the casino. Slot Check could not provide players with slot transparency if it was not for our affiliate casinos who provide us with a one-way feed of their slot data from their slot accounting system. To all our innovative casino affiliates, who have agreed to democratize their slot data, we applaud you for listening to your players and truly putting them first; and making a bold statement in the casino industry. A statement that is changing the way players think about and play slot machines, and the way casinos are thinking about customer loyalty, continuity, and how to make slot play more fun!

The data accessible to players in the Slot Check app is real-time.* It comes from the casino’s slot accounting system. This is an independently tested system that is certified to comply with gaming regulations in their respective jurisdictions – tribal or state. 100% of the slot machines in any Slot Check affiliate casino are regulated by both tribal and the state gaming regulatory authorities, where applicable. As such, players on Slot Check are assured that the machines they play at any Slot Check affiliated casinos meet federal, state, and tribal regulations.

From time to time, data errors and run-away slot meters occur. These rare events do not affect the integrity of the games or playing experience. Such events are rare and only affect the data that is viewed in Slot Check. If you see anything in the app that does not look right, please Contact Us. We want to hear from you. Be assured that we are always working to improve data integrity and performance.

*Real-time is a relative term. Slot Check data is refreshed in the app every 2-5 minutes. This timeframe may vary as it all depends on how fast we can get it to you, since it has to travel from casino to cloud and then onto your phone, tablet, or PC. The strength of data connection and other factors may affect the speed at which fresh data points appear in the app. We are always improving.

Each slot machine in Slot Check affiliated casinos have been tested to ensure that they produce randomly generated results that payout in compliance with the state’s casino gaming regulations. For example, slot machines at tribal casinos in the state of Wisconsin are tested to produce randomly generated results that payout to player (POP) at least 80% of the monies it takes in during their life cycle, per the Wisconsin Department of Gaming. Most tribal slots in Wisconsin are set to pay out above 90%. In Slot Check, you can see POP and you can see how much each slot has Returned to Player (RTP) in the last hour to the last 30 days.

Note: Slot machines in the bars and taverns in Wisconsin are not regulated. 

Slot Check only works with trusted casinos that exhibit sound regulator and compliance practices and promote responsible gaming behavior. Slot Check is only available to carded players.
