How Do Online Slots Work?

We all enjoy spinning some reels. Whether you prefer classic slots or the more modern 3D ones, they all operate on the same mechanics. Each and every one of them uses a random number generator that creates unique number sequences every millisecond. This makes all the slots fair and unpredictable. 

So if, for example, a slot has just paid out a jackpot, the odds will remain the same as if this jackpot has never been won. Online slots have no memory. You can compare them to flipping a coin - just because you landed tails five times in a row, it doesn’t mean that heads is sure to land in the next flip.

There’s a lot of mathematics going on when it comes to online slots. And these equations also influence the payout rate (Return To Player). The RTP represents how much a slot machine will pay to its players for each coin wagered over time. It usually ranges between 82% and 98%.
