A narrow depression, perforation, or aperture; especially one for the reception of a piece fitting or sliding in it. Also, a position in a schedule or sequence. For example, I booked your haircut for the 2 p.m. slot.
A slot is a dynamic placeholder that either waits for content (a passive slot) or calls out for it (an active slot). It can be mapped to a scenario with an Add Items to Slot action or a targeter, and then the content of that slot is dictated by the scenario. It can also be mapped to a renderer, which specifies how the slot is presented on the page.
Slots are designed to accept a minimum bet, which is typically equal to the amount of credits that appear on the screen. Depending on the machine, this may be as little as a penny. In the case of a progressive machine, this bet contributes to a jackpot that increases over time.

Increased hold decreases the average time that players spend on machines, so it reduces the machine’s overall profitability. It also makes the machine less attractive to new players, and may discourage them from making a long-term commitment to the brand.
