Gambling

According to the Wikipedia Online Encyclopedia, a casino is a building that accommodates casino gambling. Customers may gamble by playing slot machines or other games of chance and some skill. Casino gambling games usually have mathematically determined odds built in that ensure the house retains an advantage over the players. This advantage is called the “edge”. “Payout” is the percentage given to players. Some statistically even games may take a commission or tax, a "rake" on bets customers make against each other.
