The Math Behind Online Slots

You can find a wide variety of online slot games at reputable casinos. They can range from simple to intricate and feature various themes, reel configurations, symbols and audio visual side effects. Some even offer progressive jackpots and other bonus features. However, it is important to understand how they work under the hood to maximize your winning potential.

The math behind online slots will determine the chances you have at profiting from them in the long run. There are a couple of mathematical characteristics that will affect this: RTP and volatility/variance.

RTP is a percentage that tells you how much money the slot game should return to players over an extended period of time. It is determined by a machine’s house edge and other factors. The higher the RTP, the better your chance of winning.

Volatility is a factor that influences the number of small wins a player can expect. It is usually classified as low, medium or high. A low volatility game will offer regular wins while a high volatility one may only pay out occasionally but can reward big wins when they do occur.

Aside from the RTP and variance, other factors can also influence the amount of money you win when playing an online slot. For instance, some slot machines have special symbols that can increase your chances of winning, such as Wilds or Scatters. These symbols can substitute for other symbols, create lines of three or more symbols and trigger various bonus features. In addition, there are branded slots that are themed after movies, TV shows, sports celebrities and rock bands.
