A narrow opening, especially one for receiving something, as in a machine or container. Also: A position within a group, series, or sequence; a time slot.

In video slots, symbols that appear on a payline are weighted differently than in reel machines. Manufacturers can adjust the frequency of symbols, which gives players more chances at winning without paying more coins. They can also add additional features like regular multipliers (like 2X or 3X), Wild Multipliers and Progressive Multipliers which increase with each spin of the reel.
Another way that video slots differ from reel machines is in the ways they calculate payouts. In reel machines, payouts are fixed depending on the number of coins a player bets per spin. This method of calculating payouts limits jackpot sizes and reduces the probability of hitting a winning combination. However, some video slots have clever statistical models built into them that can improve a player’s odds at winning by changing the weighting of symbols on each reel.
If a slot is playing well and paying out a lot of money, it is said to be hot. If it isn’t, it is said to be cold. Some slot games also keep a percentage of every wager and add it to a progressive jackpot that will eventually hit, allowing a lucky player to walk away with millions of dollars.
