Online slots guide – Slot machines explained

Slots are currently the most popular casino games. The basic rules of this game haven’t changed since 1899 when Charles Fay assembled the first slot machine. A player bets and spins a set of reels with symbols. Each of these spinning reels stops at a random position. The player wins if the reels stop in a way that they make a line of the same symbols. The rarer the winning symbols, the higher the amount of the win. The size of the win for each winning combination is defined in the paytable.

Nowadays the randomness of mechanically stopped reels has been replaced by random numbers generated by a computer, but the principles remain same. These principles of randomness are honoured by every licensed game provider. The randomness of slots has several very interesting consequences, and it is important for every smart slots player to understand them.

How slots work

The majority of online slots still use reels to represent the result of each spin. Despite the fact that the reels are rendered by a computer, the game math under the hood still has 3 to 5 sets of symbols (virtual reels) that stop at random positions. Why change something that has worked fine for years, right?
