How to Determine the Fairness of a Slot Machine


In order to determine the fairness of a slot game, you need to understand several factors. These include the Reels, Symbols and Return to player. Once you know these important factors, you can find the right slot for you. In addition, you can learn more about the different types of bonus features offered. You can find these bonus features and their payout percentages on the Payback percentage page.

Payback percentage

The Payback percentage of a slot machine is a statistic that relates to how much a player will win after playing a machine for a specified period of time. Generally, the higher the bet, the higher the payback percentage. For example, if a person plays for 40 hours on a machine with a 94 percent payback, he will receive approximately 1,200 credits. Higher denomination machines are also associated with higher payback percentages.

The payback percentage of slot machines varies from casino to casino, but in Las Vegas, the average is 92%. Video poker machines have much higher payback percentages, ranging between 95% and 99%. Therefore, if you’re looking to improve your payoff odds, switching from slots to video poker is a smart move. However, remember that the payback percentage is not the same as the return on investment (ROI).


Reels are the basic component of a slot machine, and they can make or break the outcome of a game. Some video slots use cascading reels, which cascade from the top to the bottom. This type of reel arrangement creates an interesting visual experience. As a player makes a winning combination, the symbols on the top part of the reels will disappear and new ones will appear in their place. This allows players to add to their bankroll and maximize the chances of a bonus round.

The cascading reels feature has become popular in recent years. The spinning reels and cascading paylines add more depth to the game and increase the player’s chances of winning. This feature is common in newer slots that use modern software.


Slot symbols can help a player make a big profit. These symbols can be multipliers, wilds, or symbols that combine two multipliers. A combination of two multipliers can increase a player’s payout by as much as six. These symbols can also trigger special bonus features. Bonus symbols can be free spins, cash prizes, or progressive jackpots. These symbols work similarly to scatters, though they don’t usually award payouts.

Slot symbols have changed throughout history. Some symbols, which were popular centuries ago, have since become less relevant. For instance, the horseshoe was used for gambling in the middle of the nineteenth century. It was also used in the early days of horse racing, where it was associated with good luck. While the horseshoe may be outdated, it still represents gambling and good luck.

Return to player

The Return To Player (RTP) value of a slot game is a crucial aspect of choosing a casino to play in. Typically, online casinos will display this information in the Help Section of their game. If they do not, make sure to contact the casino to request this information. This will ensure that players know exactly what to expect from their session.

The RTP rate of a slot machine is expressed as a percentage. It varies depending on how many lines are played and what choices players make. These percentages are calculated over millions of spins and should be used as a guide for players.
