    Common Myths about Slot Machines

    Will your slot machine strategy actually work?

    Let’s answer some common questions.

  • A fishing rod extending over a calm river with a small fish caught on the line, surrounded by a foggy and serene natural landscape.

    Does a "near win" mean that I'm close to winning?

    There is no such thing as a “near win” or a “near miss.” If you receive less money than you paid to play, then that is a loss.

    The probability that you will win next time does not change.

  • Can you predict which machine is close to a payout?

    Slot machines are neither “hot” nor “cold.” There are no “loose” machines.

    All machines operate using a random number generator. The probability of winning is always the same. Each machine has fixed odds that do not change.

  • The photograph captures a portion of the sky with a visible waxing or waning moon in the center, surrounded by scattered clouds. Some green leaves from a tree are visible in the lower left corner.

    Can the timing of a spin affect the outcome?

    It is impossible to time a win, because your chance of winning never increases or decreases.

    The time of day or day of the week has no effect on wins. The rate of pushing buttons or time between bets has no effect on the outcome. Playing two or more machines at the same time does not increase chances of winning.

  • Golden grass field on a hillside with a clear blue sky.

    Will my payment type affect whether I win or lose?

    A player card is not able to alter the probability of the game, and neither can a free play.

    A slot machine’s random number generator does not change based on your payment type.

How Do Slot Machines Work?

  • Class III slot machines are based on random number generators (RNGs). RNGs continuously produce random numbers, even when no one is playing the machine. The numbers are generated multiple times per second.

  • The numbers that are generated by the RNG are matched with the symbols of the slot machine.

    Some symbols will have many numbers associated with them; this increases the odds that this symbol will appear.

    Some symbols have very few numbers associated with them; this lowers the odds of that symbol appearing.

  • The cost of play on slot machines is built into every spin.

    For example, if the payout is 90% to the customer, then the cost of play is 10% per spin.

    This means that if you spend $1 per spin, on average you would have $0.90 remaining, and your cost of play would be $0.10 per spin.

  • The average payout includes all types of wins.

    Using the example above, if the slot machine has a 90% average payout, incremental wins and jackpot wins ($1200 or more) also count in the 90% payout.

    Jackpots make up only 1% of all payments.

  • Neither casinos nor customers can control the outcome of a spin.

    All legal machines and all casinos in Oklahoma are monitored by the Oklahoma Office of Management and Enterprise Services, Gaming Compliance Division.

There is no skill to playing slots, and there is no strategy of play that increases the chances of winning.

    Warning Signs

    Do you know the signs to watch out for?

  • Long exposure photo of a dark road at night with car headlights creating light trails, curving into the foggy distance.

    High Frequency of Play

    Slots have a high rate of play, because the time between one spin and the next is very short.

    Higher rates of play are associated with higher risk for gambling disorder.

    Using Gambling to Escape

    The sights and sounds of a slot machine are designed to trigger dopamine.

    If you are gambling to escape difficult emotions, that can be a sign of a problem.

    Other cognitive, social, emotional, biological, and genetic factors can also increase your risk for developing gambling disorder.
