There is no strategy that can really help you to win when playing slots Never believe if somebody says that he has an incredible winning strategy. The outcome of slots is accidental. The slots don’t have memory, that’s why it is not wise to try to outwit them. The strategy can be represented only by a number of tips. Different slots have different payouts. So play slots with the higher payout. You want to find anything above 95%. When playing slots you must always know the odds and probabilities of the slot you are playing. Before you start playing slots get acquainted with the payout schedule. Determine your losing limit for the day. Stop playing when you reach this losing limit. When playing remember that you can win as well as lose. Give up the machine that isn’t paying out and is not going to. If the machine pays out good you’d better make higher bets. When you're slumping, bet less. Find a machine that suits your bank-roll. Look for a dollar machine, and have some fun. Cash out the credits you’ve won before leaving the slot machine you’ve been playing. Sounds obvious, but a lot of people forget! Always play what you know.

I tis important to now what you are playing.
You should know exactly how many coins you are supposed to insert into a machine. Always cash out your credits before leaving a machine.
Slots shouldn't be a stress for you, just enjoy. If you feel lucky increase your bets and vice-versa.

Slots Rules: Understanding the rules of the game is always important, no matter what game you are playing.

Rules for playing Slots
Only slots have so simple rules. In fact it is so because there are no rules at all. All the player has to do is drop coins in the slot and pull the handle or push the spin button. The mission of the game is to match preselected symbols on the pay line, (or paylines, depending on the machine being played, there can be up to 5 pay lines on some machines), to earn credits. Slots machines have different betting limits. They can be as low as 5 cents and as high as 0.
Especially beginners like slots. They don't have to worry about rules and regulations, or being laughed at by the other players for making a bad play, all they have to do is try to hit the jackpot by matching the highest paying symbols on one of the pay lines.

United States

Classes Of Slot Machines
No federal law governs slot machines. There is no universal classification for all states. There are restrictions on the type of slot machines that can be used in a casino or other gaming area in some states. "Class III" (or "traditional") slot machines operate independently from a centralized computer system. Every play has equal chances of winning any payout. Nevada or Atlantic City have more Class III slots than any other state. They are sometimes referred to as "Vegas-style slots".
There is a connection between "Class II" slot machines ("video lottery terminals" or "VLTs") and a centralized computer system. The outcome of each wager is determined by it. The chance of winning a series of limited prizes is equal for each machine. A fee for each Class III game is paid by the casino to the state. The regulations for Class II games are not so tight.

Class II Game Characteristics
The player is playing against other players. They are competing for a common prize. One player always wins the game. The game stops when the winner appears. There is a certain number of wins and losses in a given set of wins. The combimation that has already occurred cannot occur again until a new batch is initiated. The games are dependant on each other. The player must be an active participant. There is the same set of numbers for all players.

Class III Game Characteristics
The house plays against the player. Each game is independent of previous games. Any possible outcome can occur in any game.

These reels are spun. The machine pays winnings if certain combinations of fruit appear. Slot machines seen in casinos and elsewhere around the world are similar to these machines. But some extra features can be found. There exists a strict jackpot limit. Fruit machines in the UK also almost universally have the following features. A player may be given the opportunity to hold one or more reels before spinning. This can sometimes increase the chance of winning. A player may also be given a finite number nudges following a spin. The term nudge is used to denote a single-step rotation of a reel of the player's choice.

According to the main slot classification there are two types of slots. They are straight slots and progressive slots. If you play slots then you are paid in accordance with the payout schedule, which is always shown on the slot. Inside the straight slot group four more types are distinguished. They are multiplier, bonus multiplier, multiple payline and buy-a-pay slots. The bet amount determines the sum of the payout in multiplier slots. Bonus multiplier slots are characterized by a bonus round, which is activated if making maximum bets. The principle of multiple payline slots is that the number of enabled payline depends on the number of coins bet. The Buy-a-Pay slots are profitable only if you place maximum bets. Progressive slots are characterized by the big jackpot, which progressively gets larger and larger, as every coin is put in. The amount of the Progressive jackpot is always shown on the slot.
