Depending on the type of slot game, the symbols can be arranged horizontally or vertically. The number of paylines may be a fixed number or a range. Some games also have wild symbols, which can substitute for most other symbols. These special symbols may also be stacked across the entire reel, or may offer a lower prize for non-natural combinations.
Some of the more popular features on slot machines include Hold&Spin. During this feature, special symbols stay on the screen until another one lands. During this time, credits are awarded for certain combinations.
Some slot machines also have bonus rounds. These bonus rounds typically are aligned with the theme of the game. A bonus round usually gives players the chance to win bonus credits, credits for certain combinations, or free spins. Some bonus rounds can be repeated, meaning players can play several bonus rounds in a row.
These machines also have a “max bet” button, which allows players to bet the maximum amount on each line. The “max bet” button can be turned off if a player prefers not to bet the maximum amount.
A game’s payout percentage is also an important factor in determining the game’s profitability. The higher the payout percentage, the higher the odds that a player will win.
The paytable, or list of winning combinations, is also important. The paytable is usually found on the machine’s face, or on the help menu. The paytable lists credits for each winning combination.
