A slot machine has three or more vertical reels seen on a screen which spin when a button (or a lever) is pushed by the player.
Each reel has a set of patterns or symbols.
These symbols are usually brightly colored and easily recognizable, such as images of fruits, numerals or letters, and simple shapes such as bells, diamonds, or hearts.
Once the spinning reels stop, the game is determined by the aligned front symbols.
The player wins the bet if the same symbol is aligned horizontally in each reel.
The higher the amount of the bet, the higher the payout will be. In addition, each symbol has a different value, which determines the award received.
Basic slot machines have three reels and figures must align in one horizontal payline (usually the front line).
However, traditional but more complex machines have up to five reels and three horizontal paylines, in which players can choose to gamble with just one line or with several at the same time.
Naturally, this will determine the bet level and therefore its payoff odds.
In some cases, players can use up to five lines – this includes two diagonals- in order to match the symbols.
Newer slot machines can have up to 21 different paylines, allowing lines with angles that form multiple combinations of figures.
This means that visible symbols that are not aligned on the main horizontal may be considered for winning combinations.
They can use animated cartoon characters and even images of popular actors or singers as matching symbols.
