The symbols in a slot machine are responsible for giving payouts and they vary depending on the type of game. The standard reel symbols include fruit icons such as lemons, strawberries, melons and oranges. They also include card numbers from Tens to Aces, as well as wilds. Wilds act as a joker and can substitute for other symbols on a payline, increasing the chances of landing a winning combination.

Other special symbols in a slot are called scatters, which can trigger different bonus rounds. These don’t need to be aligned in a payline to work, but players should check the pay table before playing to make sure that they understand how they work. In addition, scatters can be stacked to take up multiple spaces on the reels and increase the odds of winning.


Paylines are a crucial part of slot machines and they affect how winning combinations are formed. They can be fixed or adjustable and can run horizontally, vertically or diagonally on the reels. The easiest way to find out how many paylines a slot has is by consulting the game’s pay table. The pay table is displayed on a tab on the machine’s screen and can be accessed by clicking or touching the info button.

The number of paylines in a slot determines the amount of money you can win. To form a winning combination, you must have matching symbols on an active payline. Traditionally, winnings are made on a single payline from left to right, but modern games often offer All-Ways pays, which means there are multiple ways to win.

Bonus rounds

Bonus rounds in slot machines can add an extra element of fun and can give players the chance to win big payouts. These features can vary widely from game to game, but are usually triggered when specific symbols appear in a winning combination. They can be a special session of free spins with different reels and a higher payout potential, a second screen minigame or an added multiplier on wins.

The Rocky slot machine’s Knockout bonus feature is a good example of this type of round. It is triggered when two of the same symbols land on the first and fifth reels. This bonus round allows players to choose between Apollo Creed, Ivan Drago or Clubber Lang and then fight their opponent in a video clip from the movie.

Weight count

Weight counts in slot games are important because they help players estimate their winnings. This method involves weighing the value of coins or tokens removed from the machine by casino employees. This helps players plan their gambling budgets and maximize their returns. However, it does not guarantee that they will win every time. In addition, some slot machines have stacked wild symbols that increase the player’s chances of hitting a winning combination. These symbols can be either regular or bonus symbols, and they will behave differently depending on the game and the rules.
