The invention of the slot machine in the late 19th century was an important event in the world of gambling. Slots quickly surpassed other forms of entertainment in popularity. In modern casinos they are chosen by more than 70% of players. Sometimes you can read that the idea of a slot machine inventor Charles Fey borrowed from poker. And it is true, often cards are used as symbolic pictures on the reels, and the combinations are somewhat reminiscent of poker. But still, even if the engineer started from the card game, in the end he went quite far from it.

The main advantage of slot machines is the independence of the player from both partners and the dealer. Slots are played alone. Fey took care of that. He owns a patented automatic mechanism for receiving and issuing coins. Now a person could simply walk into a bar, drop a nickel, pull the handle, and win ten times that – that was the jackpot in the first slot – 50 cents, not bad money at the time.

Later slot machines got an electric reel drive and beautiful lighting. But the principle remained the same: the same symbols on the 3 reels should line up in one line. Since drawings are made with different frequency, and the probability of their composition in combinations is different. For the rarest combinations are the biggest reward. And vice versa.

Modern slot machines use the same scheme, but the device they are completely different from the old slot machine. Now it is a specific computer programs. Land-based machines externally similar to their ancestors, but they have the most modern stuffing. As for RocketPlay online slots, they are exactly the same programs as those running inside their land-based counterparts.

The computer age has completely changed the economics of slot machines. Some land-based casinos still use coins or tokens to pay for play and give out winnings, but the newest slot complexes accept all electronic payments. As for online slots, they inherently only work by cashless payment.

The percentage of return to the player is an average value. It follows that it converges with the practice only after an astronomical number of moves.
