Slots in which you can win money are the ones that have the highest payout percentage. Also known as return to player (RTP) percentage, the payout percentage is the average return you can expect to get in winnings when you play a slot machine or slot game.

The RTP is a theoretical number related to the house edge associated with the slot game. The higher the RTP, the more likely you will win real money on the particular slot machine. Let’s look at an example of a high-paying slot game like Book of 99 by Relax Gaming:


Book of 99 has an RTP of 99%


You bet $100 repeatedly on the slot game


The slot game will theoretically return $99 in winnings to you. Remember that is an average return. In reality, you can win more, less, or even lose the entire amount.

Payout percentage (RTP) is not the only factor to keep in mind when looking to play the best slots for real money.

Here are other important things to consider when choosing the best online slots:

  • Check online threads, internet forums, and message boards

    You can check forums and sites like Reddit,, and even social media posts. Most players talk about the best online slot machines and casino games you can play at places like Macau, Las Vegas, Atlantic City, and online.

  • Research gaming software developers

    You can read reviews, ratings by real gamblers, or descriptions of online gambling software. Developers like Microgaming, Pragmatic Play, and NetEnt are famous for producing slot games with high payout percentages and bonus features.

  • Check the variance or volatility of the slot game

    This is a measure of how frequently you can win while playing the slot game. High-variance slot games pay less frequently, but the money you get when you win is larger. Low variance or low volatility slots pay more often, but the amount of winnings is usually small.
