Is There a ‘Best Time of Day’ to Play Slot Machines?

Some slot machine players are convinced that playing at a certain time of day will make a difference in their ability to win or lose.

STATUS: Slot machines don’t factor time into paybacks.

I’ve already covered in depth how casinos aren’t manipulating slot machine payouts based on locations, casino’s whims or whether they’ve paid lately. But some players claim to always win at a certain time of day, for instance, with the belief that this is because the casino is setting things up that way.

The RNG in a machine doesn’t know what time it is, just like it doesn’t have a memory of previous spins. It’s actually against gaming regulations for external factors like previous spins or historical payout to be used to calculate what future spins will pay. So this one can be chalked up to confirmation bias.

I’ve mentioned that phrase before, but haven’t really defined it, so let’s take a moment to do so.

What is Confirmation Bias?

The idea behind it is simple: If you have a certain belief, you’re more likely to recall and store examples that lend credence to that belief or theory, and more likely to throw away examples where it doesn’t work out.

For instance, if you’ve had some major handpays late at night, and also some massively poor sessions late at night, but you believe casinos are more apt to pay at night, you’ll be more likely to remember the handpays and forget the routings. Even not obvious or guaranteed examples can and will be used to support the position.

Confirmation bias has its basis in psychology, and has been studied heavily. Gamblers tend to be a superstitious folk, and so anything that may lend credence to a superstition that make people feel lucky or that they’re more likely to win can pick up steam very quickly. The inverse, that casinos are somehow cheating players, also pick up steam for similar reasons.

While most of the superstitions are harmless, they’re just that, superstitions. Games are programmed to pay over time, through millions of spins, based on a math model, not what’s on the clock.

So don’t feel like you have to go to a casino at 3 a.m. to win. You’ll be just as likely to win at 3 p.m.
