Slot machines are a popular way to gamble in Las Vegas. In most cases, you put money into the machine and hope to win a prize.
However, not all slot machines take coins. .
Some slot machines only take bills, while others may take both coins and bills. There are also some machines that only take credit cards.
Some people believe that slot machines that only take coins are harder to win than those that accept both types of currency. However, this is not always the case.
In fact, many people believe that winning on a slot machine that takes both coins and bills is just as likely as winning on a machine that only takes bills.
