Playing in a casino is primarily associated with slot machine games such as the one-armed bandit. Previously, machines had a handle on the side with which the drum was turned, hence the name of this slot machine. Nowadays, it is enough to press a button. One-armed bandit is one of the simplest games available in a casino. It should be emphasized that such machines do not offer record winnings of the order of millions of euros, but a win of several tens of thousands of dollars is possible.

Slot machines in online casinos are more technologically advanced. This is reflected not only in the graphics of the slot, but also in the possibilities of the game. Many complex systems, internal mini-games, payout multipliers are usually quite complex. Online slot machines usually offer a progressive jackpot, due to which winnings can be significantly higher than in classic machines.
