Slot machines of this type were among the first machines that appeared in the history of casinos and gambling.
One Armed Bandit – a classic type of gaming machine with a mechanical lever that drives the reels.
The name of these slots is due to their appearance, as the lever resembles a hand. At the dawn of gambling, one-armed bandits were very popular, but later they were replaced by models with a more functional and practical button system.
However, such slot machines are still found in offline establishments. Moreover, developers of software for online casinos periodically release online slots stylized as one-armed bandits.
