In the context of online slots, the term "blank" typically refers to a symbol or space on the reels that does not have any value or specific function. In many slot machines, the reels are filled with various symbols, which can include images related to the theme of the game, such as fruits, numbers, letters, or other symbols.
Blanks are essentially placeholders that do not contribute to winning combinations or trigger any special features. They are included on the reels to create a balance in the game and determine the odds of winning. The presence of blanks alongside other symbols affects the overall probability of landing winning combinations.
The arrangement of symbols, including blanks, on the paylines or reels determines whether a player wins or loses on a particular spin. Blank spaces can appear between other symbols, and their position in a combination can influence the outcome of the game.
