In modern casinos, gamblers will find a wide variety of slot-machine types. Some of them are described below.
Progressive Slots are linked in a bank of machines so that a certain percentage of every bet goes to the progressive jackpot pool. This jackpot pool belongs to a group of slots in a casino, or even in different casinos.
The more people playing on the linked machines, the faster the jackpot increases. Finally one lucky player will scoop the jackpot he/she hits the highest winning symbol combination. To hit the jackpot the maximum coins must be played.
A multiplier slot machine doesn't have a jackpot, but the payback for additional coins is a multiple of the payback for a single coin.
Some slots have an additional wheel that can be played after a win. So a player has a 50/50 chance of doubling (or losing) his/her winnings.
Nudge machines have a light mounted on them that comes on occasionally. When it on, the player may move (nudge) a wheel forward or backward one location to get a certain combination of symbols on the payline, so a losing bet can become a winner. The house edge on these machines is usually the same as for regular slots.
The special prizes is waiting for you if you get a special symbol combination or collected certain symbols. If you do, you will enter a bonus round. Usually a player have to bet maximum coins to qualify for the bonus round.
These machines have a special wheel mounted on top. When the winning symbols appears on the slot machine this wheel spins and the player has a chance at winning the wheel-of fortune jackpot.
