During the 1920s, slot machines became extremely popular in resort areas. This popularity persisted even during the Great Depression. Despite legislation that banned their sale and transportation, many people ignored the restrictions and continued to play. The laws were eventually relaxed, but not before some people began exploiting their newfound popularity. Today, slot machines use microprocessors to calculate the odds of winning each game. Because of this, the odds of winning a jackpot have become much higher.
Wild symbols are another important feature that distinguishes modern slot games. They act as substitutes and can also award multipliers. In addition, some slots have sticky wilds, which stay in place while the reels spin free. Bonus modes can also be triggered by bonus symbols, which are also commonly found in modern slots. Bonus modes are games that reward players for matching specific combinations of symbols. Some games even reward players with extra credits if they match three or more symbols.
Paytables can be found on slot machines to determine how much you can win if the symbols on the reels match. This information is often found on the face of the machine or in the help menu. Older machines usually list the pay tables above or below the spinning wheels. Video slot machines display them in a help menu. A pay table can be helpful in determining how much a player can win, and how much a winning combination would earn.
