How to Know If a Slot Game is Fair


How do you know if a slot game is fair? To understand how slot machines work, you should first understand what a random number generator is and how it determines the outcome of a spin. This random number generator is found in every slot and is designed to generate random numbers within a large spectrum. The outcome of a spin is determined as soon as you press the spin button, and despite what you may think, stopping the reels does not change the outcome. Random number generators are not entirely random, and until this technology is perfected, we will have to accept the fact that the results are determined by the computer’s algorithm.


The RNG for slot machines is a microchip that randomly generates numbers throughout the game. The generated numbers determine where the reels land, and the levers and buttons are designed to display the position of the latest number generated. The RNG should be random enough to give players a fair chance of winning. Several major software providers test their games using an independent third-party company to ensure they are random. The iTech labs, for example, tests the random number generator’s algorithm to ensure it is non-repeatable and predictable.

Physical reels

Physical reels in slot machines are traditional symbols of gambling. But, with the development of electronic and video technology, they have fallen by the wayside. Despite their recent revival, physical reels continue to lose market share to their video and electronic counterparts. This is because, despite their similarities, these games do not pay out the same way every time. In the end, the payoffs that you get are dependent on the hit frequency and the payback percentage.

Payback percentage

The payback percentage of a slot machine refers to how much of a player’s bet will be returned to them after a specified number of spins. These numbers can range anywhere from seventy-five percent to ninety-eight percent. However, the payback percentage is of no relevance if the player doesn’t understand how these figures are calculated and how these payouts relate to the number of spins the player makes.

Random number generator

During the time when there is no game being played, a random number is generated and sent to a slot machine. A main server connected to all of the slot machines calculates this number thousands of times a second. The output of this algorithm is what is displayed when a player presses the button on their slot machine. This number is the one that determines if they will win. If the player pushes a button, this number is sent back to the main server and it is this algorithm which determines the outcome.


If you play on a slot machine with a jackpot, your chances of hitting it are incredibly slim. A single spin on a slot machine can result in a jackpot if you land five symbols of the designated symbol and no other symbols. The same applies to games with wilds. However, if you do manage to land the jackpot, it will not count towards your Biggest Win stat. Here are some tips for increasing your chances of hitting a jackpot on a slot machine.
