There are a lot of myths and superstitions about slots.
You can spot a winning slot machine.
The only way you'll spot a winning slot machine is when the bells are ringing and the money is dropping. RNG is the main element of every slot machine and one never knows what combination it will form.
Casinos place loose slots near the cashier, aisle ways, etc.
If this were true, it would be the only machines anyone would play. A casino mixes slots all over the casino floor. No one with any experience at playing slots would make a statement like this.
Count the number of symbols on the reels to determine your odds.
This is mathematically impossible, remember the RNG (random number generator) determines the stops. Thereare literally millions of combinations on a 3 reel slot machine, so there is no way of determining odds by the symbols on the reels alone.
Casinos can tighten or loosen slot machines from the back office.
It is not as simple as that. The casino can’t just change the chip of the slot machine. It is illegal and it has to be permitted by the commission.
A slot machine that has not been paying is due to hit.
Absolutely false. The RNG assures this. You have an equal chance of winning on a losing machine as you do on a machine that just paid out the jackpot.
Pulling the slot machine handle produces more wins than pressing the spin button and visa versa.
It is also a mistake. These things are only mechanisms for beginning the game. The machine knows whether you win or lose before the symbols begin to stop.
Playing with hot coins improves your chances.
Once again, the computer determines a win or loss and the temperature of the machine or moneyirrelevant. Although it's funny that people still burn their fingers with lighters believing this works.
Casinos set slot machines to payback more on the weekends.
Wrong again. Your odds of winning are the same no matter if it's 4:00pm Monday, 8:00pm Saturday or 3:00am Wednesday. Casinos can not and do not do this.

Slots Rules: Understanding the rules of the game is always important, no matter what game you are playing. Slots are the easiest casino games. The rules are very simple. The player has to insert coins in the slot machine, then push the button or pull the handle and wait for the combination of symbols. If the bells ring and lights flash, open up your pocketbook because you are in the money! Enjoy, but never gamble with more money than you can afford to lose.
Rules for playing Slots
Only slots have so simple rules. In fact it is so because there are no rules at all. The principle of the game is the following: the player inserts coins, pulls the handle and then checks the combination of symbols on the lines. The main objective is to match certain symbols on the paylines. But the player can do nothing to affect this. Slots machines have different betting limits. They can be as low as 5 cents and as high as 0.
It is a popular game for beginners because it is just them against the machine. 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.

The USA

Classes Of Slots
Slot machines aren't governed by any federal law. There is no universal classification for all states. Some states have restrictions on the type of slot machines that can be used in a casino or other gaming area. A centralized computer system operates "Class III" (or "traditional") slot machines. Every play has equal chances of winning any payout. Nevada or Atlantic City have more Class III slots than any other state. "Vegas-style slots" is another name for them.
There are "Class II" slot machines ("video lottery terminals" or "VLTs") which are connected to a centralized computer system. It determines the outcome of each wager. The chance of winning a series of limited prizes is equal for each machine. There is a fee for each Class III game that the casino has to pay to the state. Class II games are not so tightly regulated by the state.

Class II Game Characteristics
The players are playing against each other. There is a common prize for which they are competing. One player always wins the game. The game continues until there is a winner. In a given set there is a certain number of wins and losses. Once a certain combination has occurred it cannot occur again until a new batch is initiated. The games are dependant on each other. The player must be an active participant. The same set of numbers is played by all players.

Class III Game Characteristics
The opponents are the player and the house. Each game is independent of previous games. Any game has any possible outcome.

Slot Clubs
In American casinos there are "slot clubs" the membership of wich is free. A small fraction of the amount of money that is bet is returned in the form of comps. These clubs require that players use cards to insert into the slot machines. The differences in the maximum theoretical returns can be significant thanks to comps or "cash back" from these clubs.

There is similarity between these machines and slot machines seen in casinos and elsewhere around the world. These games have lots of extra features. The jackpots from these machines are limited. 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.

The main classification of slots distinguishes two types of slots: straight and progressive slots. The main principle of the straight slots is that you get paid according to the schedule listed on the machine itself. Straight slots in their turn can be divided into multiplier, bonus multiplier, multiple payline and buy-a-pay slots. The bet amount determines the sum of the payout in multiplier slots. The main principle of bonus multiplier slots is a bonus round, which becomes active if you play with maximum bets. The feature of multiple payline slots is that the number of active payline is dependent on the number of coins being bet. The Buy-a-Pay slots are profitable only if you place maximum bets. Progressive Jackpot is the main characteristic of the progressive slots. Progressive jackpot grows with each coin being bet. The amount of the Progressive jackpot is always shown on the slot.
