A slot is a narrow opening, as in a door or window, into which something can be fitted. The term was probably borrowed from the Middle Dutch sloet, from Proto-Germanic *slutila (source also of Old Frisian sletel, German schloss “a bolt, lock, castle”), from PIE root *slauthu (to shut, close).
In an online casino, slots are digital reels with symbols that spin and stop when a player places a bet. When the reels stop, they reveal a sequence of symbols and payout amounts according to the pay table. Some slots offer additional bonus rounds and features that require players to build their way to them, as opposed to being triggered by a random event on any given spin.
When playing online slots, the gamer will select the amount they wish to bet and then click on the “Spin” button. The reels will then display random symbols. If the symbols match on a payline, the player wins. The payout amounts will be listed in the paytable, which can include wild symbols, scatter symbols, and bonus symbols.
Slot is a dynamic placeholder in the ATG Personalization Framework that holds content dictated by a scenario using either an Add to Slot action or a Targeter to fill the slot with the contents of the target repository item. Slots and scenarios work together to deliver content to the page, while renderers specify the presentation of that content.
