Online slots have a general objective, which is to create lines of matching symbols, with the winning payoff being proportional to the amount of money bet. Modern slots have five vertical reels with three or four active rows. These reels are separated by a single line called the payline. The paylines are the possible paths that can be followed to create a winning combination. They can be horizontal or diagonal. The player can bet on any combination of symbols. Wild symbols can substitute for any other symbol in the same line, and the resulting combination will win the jackpot.

The RTP value is a mathematical calculation that tells how much an online slot machine will pay back over time. It is usually expressed in a percentage, such as 96%. This means that if you bet $100 on a game with 96% RTP, you will receive $966 of your money back. While this is a statistical calculation, it does not mean that a certain game will pay out 100%, nor will a single spin yield a 100 percent return.

The Return to Player (RTP) value tells how much a slot machine will pay back over time. It is typically expressed as a percentage, so a 96% RTP will pay out $96 for every $100 wagered. Nevertheless, this calculation is theoretical, and you should never depend solely on it. Therefore, you should make sure to read the RTP of the game before you place a bet. You may find that a particular game will have a higher or lower RTP than others.
