Online slot is a casino game where players place bets and spin the reels in order to win. The games are available at many different sites and can be played from any computer or mobile device with an internet connection. They use software based random number generators to determine the outcome of each spin and are therefore considered fair. They are also available for both real money and free play.

A player can select the coin size and number of coins per payline in order to customize their bet amount. This allows them to place bets ranging from a few cents to hundreds of dollars per spin, depending on the rules of the particular game. Some games require the activation of all paylines, while others offer a more flexible system that allows players to choose which lines they wish to activate.

Many newer online slots also include extra features like Wilds and Scatter symbols. These add a extra layer of excitement to the game and can often help to link up lines and create winning combinations. The exact details of these features will be outlined in the game’s paytable.

Some newer online slot titles also feature progressive jackpots. This means that the prize grows with each bet placed on the game, allowing it to reach huge amounts of cash in a very short period of time. Unibet offers a range of these jackpot games and more information can be found in our article about jackpot types.
