Advantage plays in slots are relatively easy to grasp compared to other casino games, like blackjack or poker. The reason for this is that slots do not require split second calculations – they are based on simple mathematics and probabilities. That is why online casinos have so many different types of slots available.

Casinos are under tremendous pressure to maximize their all-important slot revenue. However, they also fear that if they increase the house advantage too much, players will detect this concealed price increase and choose to play elsewhere.

So, how do they keep the game fun and their profits high while keeping the house edge low? The secret is random number generators. These little computer programs are designed to create an outcome that is fair and unpredictable for each spin. In other words, each time you push the button or pull the handle of a slot machine, the computer randomly picks a number from 1 to 100,000. It then decides which reel to spin and whether the player should win or lose. This ensures that the house edge stays low and keeps players interested in the game.
