Slot Glossary

A slot machine with a fixed jackpot amount, unlike progressive jackpots, the prize of which constantly changes.

Online casinos may limit the maximum amount a player is allowed to make, called the maximum bet. Alternatively, the term refers to the option at slot machines that bets the maximum number of coins.

A straight or zig-zagged line on a slot machine where symbols must line up for a win. Slot machines usually have up to 9 paylines, though video slot machines may have many more.

By linking together machines, online casinos are able to form a large jackpot (the highest payoff), one that grows progressively with every game played. Progressive jackpots can be found for slot machines or video poker, typically, but also for other casino games, including poker, blackjack, roulette and others too. The constantly changing progressive jackpot meter is usually showcased on the front page of the casino.

Only players who wager the maximum credits qualify for the progressive jackpot and it is won only with the highest payoff combination, e.g. a royal flush in video poker. Once a player wins the jackpot, the jackpot resets to a preset minimum level and starts climbing all over again.

Progressive Slot machines are a popular feature, with the jackpot amounting by having a group of linked slot machines. Slots linked across online casinos must be operated by the same software, owned by the same machine maker, with jackpots really hitting sky-high sums of millions of dollars.

The Random Number Generator (RNG) is the basic engine that powers Slots. Modern Slot machines are computerized, with the combinations determined randomly by the machine's software, without any human involvement. The RNG generates numbers at a high rate, and the timing of when the lever is pulled determines the outcome. An advanced RNG will be as random as possible, never repeating the number sequences.

Slots, or Slot machines, are gambling machines that operate by inserting coins into a narrow opening and pulling on a lever, or in online Slot machines simply pressing a button. Slot machines are simple to operate and little strategy can be applied.

When at the Slot machines, you are in the hands of luck. As such, Slot machines are arguably the simplest casino game available and one of the most popular ones too.

Video Slots are the most complex and advanced of the Slot machine variants, with as many as 40 paylines and video game quality visuals and audio.
