Modern slot machines have symbols that are more varied than those on classic mechanical machines. They may include traditional bells, spades, hearts, diamonds, and horseshoes, as well as fruits, and playing card icons such as aces, jacks, queens, and kings. Some slots have symbols that are themed after popular movies or TV shows.
Some states, such as Alaska, Arizona, Arkansas, Kentucky, and Minnesota, have no restrictions on private ownership of slot machines; other states, including Connecticut, Hawaii, Nevada, South Carolina, and Texas, prohibit it.

This is partly because of the fact that people who play slot machines can be exposed to gambling advertisements 24 hours a day. The popularity of slots has led to the creation of gambling clubs, which offer a variety of slot machines to members.
