Slot machines have been around for centuries and have been used in a wide variety of casinos. They are essentially electronic devices that take in coins and spit out credits. The credits can be used to play other games or to cash out.
The odds of winning on a slot machine are determined by the pay table, which is a list of possible rewards given for different combinations of symbols. Slot machines with high dollar denominations tend to have better odds because there are more possibilities for rewards.
