For most players, the slots payout percentage is one of the most important considerations for online slots play. This tells a player what he or she can expect to receive in payout over the long term of playing. The percentage would be how much they receive for every $100 wagered. Naturally, players would choose the best payout slots or the games with the highest slots payout, but the percentage of payout is not always readily available.

Probability and Slots

For most gambling games, payout can be estimated using probability. An individual can easily analyze the probability of winning big with limited information. For instance, in roulette games, we know there are 19 black and 18 red numbers on the traditional European wheel. Therefore, the probability of hitting red would be 18/37 or roughly 1:2. Probabilities in slots are less difficult to calculate because of the random nature of slot spins. Therefore, the slots payout percentage can only be estimated over a very long period of game play.

Computer Simulation

Because it takes multiple iterations of play to determine the probability of slots payout, computer simulations are the best way to accurately assess any game's payout percentage. The simulation must include the number of reels, the number of symbols on each reel, and the frequency of each symbol across the reels. The computer program then must simulate tens of thousands of deals, record total payouts for the amounts wagered, and then calculate the percentage of payouts over the number of plays.

Finding the best payout slots online can be difficult because there are so many different slots games out there. New games appear almost daily. While most online gaming software developers aim for payout percentages between 94% and 96%, estimating the exact slots payout percentage alone is almost impossible.
