Most slot games have a specific theme. Typically, the symbols on the reels will be related to the theme. Some classic symbols include fruits, bells, and stylized lucky sevens.
Most slot games offer bonus features. Bonus features are typically aligned with the theme of the game. The bonus can either come in the form of free spins or a multiplier. The multiplier is a number that multiplies the winnings. The multiplier can increase based on the combination of symbols on the reels.
Multi-line slot machines have become more popular in the past few decades. These types of slot machines allow a player to bet up to 15 credits per line.
