How Slot Machines Are Rigged


Slot machines are one of the most popular games in casinos, accounting for more than 60% of gaming earnings in the United States each year. They’re easy to play and don’t require any prior gambling experience, making them an attractive option for casual players looking for a quick fix of entertainment.

They’re rigged

As you might expect, slots are rigged to pay out the most money for a given coin in, so players should be careful not to overspend on them. It’s possible to hit the jackpot by betting just a few coins, but it’s unlikely to occur often enough for it to make a dent in your bankroll.

They’re rigged to pay out the most money on every spin

As we discussed, slot machines are rigged to give you a high payout on each pull, but this is largely due to technology, which allows manufacturers to program their machines to weight certain symbols more or less than others. Consequently, symbols that appear on reels more often than others have a higher probability of winning.

They’re rigged by computer and software

As mentioned above, modern slot machines use computer technology to generate billions of combinations and outcomes each second. They employ a random number generator (RNG), which is a piece of software or hardware that assigns different probabilities to every symbol, regardless of where it appears on the reels.

They’re rigged against you

A lot of people believe that slots are programmed to have hot and cold streaks, or even to favor certain symbols over others. However, these theories are a bit of an overstatement. As we explained in our previous article, all slot machine outcomes are completely random, and the only thing that can influence them is your own luck.

They’re rigged in a number of ways

The most common way slots are rigged is by having specific patterns that flash when service is needed, if the door doesn’t close properly or if the slot is not secure. This information is displayed on the candle at the top of each machine.

It’s also worth noting that each game has its own rules, so it’s important to read the game’s instructions before you begin. This is particularly true for video slots, which typically have a HELP or INFO button that walks you through the various payouts, play lines and bonus games.

They’re rigged for taste

It’s important to remember that slot machines are rigged against you, and this applies in both live and online casinos. There are some exceptions, like progressive machines. Nevertheless, most slot machines are rigged against you, as they return about 90% of the money that’s placed into them to the player.

They’re rigged around the clock

A number of slot machines in casinos have lights that flash when they’re not working correctly, and this is particularly common on progressive jackpot machines. This lets slot attendants know if someone is attempting to enter the machine or if it’s secured, so they can quickly fix the problem before you get out.
