Some slots also have a progressive jackpot that grows incrementally as players make bets. This feature is particularly common with online slots, but can also be found on some land-based games. Some of these jackpots are very large, reaching millions of dollars. Some casinos have started offering these jackpots as an incentive to attract new players.

Some of them have themes that relate to popular culture, such as television shows and movies. Others have a more traditional feel and are designed to appeal to older audiences.
