How Do Casinos Control Slot Machines?

Many players at casinos often ponder if they can control slot machines. This misconception, however, is untrue and should be dispelled.

Though technically possible for casinos to manipulate slot machines, the potential benefits would be minimal and could potentially conflict with government regulations. Therefore, doing so is not recommended by casinos.

Random number generators

Random number generators (RNGs) are an essential element in how casinos operate slot machines. They generate numbers corresponding to symbols on the reels, which ultimately determine the outcome of every spin.

True random number generators rely on data gathered from the environment to produce truly random numbers. This includes atmospheric noise and quantum and electromagnetic phenomena such as radioactive decay.

Contrastingly, pseudo random number generators (PRNG) are software-based and use algorithms to simulate selecting a value from either an infinite or limited distribution.

These generators are usually faster than true random number generators, but they cannot guarantee a certain level of entropy at all times. Some systems take a hybrid approach by harvesting natural entropy when available and periodically seeding software-based cryptographically secure pseudorandom number generators with natural entropy. This enables them to provide optimal randomness without blocking or degrading performance while being less susceptible to disruptions than systems using only physical hardware.

Payback percentages

Payback percentage is one of the most misunderstood concepts in the casino industry. Many players mistakenly believe it means how much of their money will be returned to them in jackpots; others think the casino has some kind of switch somewhere that officials can throw to reduce payback percentage on a particular machine.

Casinos are the only way to control slot machine payouts so they meet their financial performance targets. This is done by continuously altering the odds to fit their target payback goal, whether that be up or down over time.

Altering the payback percentage of a slot machine is no small feat, even for casinos with the technology to do it. A new chip must be installed inside the machine and an entire system with predetermined outcomes must be set up before any modifications can be made.

Bonus rounds

Bonus rounds are an excellent way to win money at slots. They come in many forms, from free spins to pick ’em games. Additionally, these can have various effects like expanding wilds and win multipliers. Bonus rounds offer players plenty of chances for financial gain!

Some bonus rounds are activated automatically, while others require players to collect certain symbols or reels. Other bonuses may be randomly triggered during play.

Players who are used to consistently winning at their favorite slot machine may become frustrated. They may wonder if casinos can influence the outcomes of slot games in order to cause them to lose even more money.

Unfortunately, cheating in real-world casinos is not a common occurrence. Most establishments would face severe legal repercussions and could potentially lose their licenses.


Slot machine operations are governed by various regulations and laws. These guidelines strive to make the games fair, so no one can influence the outcome.

Casino slots are further regulated through gaming commissions. These commissions inspect the software code to guarantee that no manipulation has taken place with the machines.

This will shield players from being conned by casinos. Additionally, it encourages good behavior and prevents problem gambling.

Slot machine regulation is also heavily influenced by state law or negotiated compacts. These laws establish limits on how much a casino can pay out to players.

Additionally, slot machine odds can be adjusted onsite at a casino to increase winning chances. But this requires substantial infrastructure and building clearance to accommodate all cables running from each machine.
