As you know there are different types of slot machines. And do you know that there are even types of slot palyers.
Persistent player.
The players of this type believe that very soon there will be a period when the machine begins to pay. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
Players become so persistent if they have already spent a lot of money for this slot and haven’t got anything or if they have found a slot machine that haven’t paid for a long period of time. They believe that a big win is sure to happen right now. They can’t leave the machine because as soon as they do it will burst forth and pay out large sums. Makes sense if you have lost 0. 00 and have yet to win. The machine must pay.
Many years ago in the case of the payout players touch the coins to check whether he coins were hot or cold. If the coins were hot they believed that the machine had not paid for a long period of time. But in reality any machine has numerous lights which heat the coins.
Chaser is the next type of slot players.
Players feel more comfortable and confident because they have been reinforced with a win and gain trust in the machine. There is some kind of comfort and trust between the slot machine and the player.

Slots are one of the oldest casino entertainments. They came through a number of changes and improvement. But the objective and the principle of the game always remain the same. The player inserts coins in the machine and then wins or loses according to the outcome of the game.
In fact all slot machines are the same. They only differ in some peculiarities: odds, payouts, payout percentage and symbols. There are so many varying designs around the classic slot machine that everyone could probably find their own ultimate preferred flavour.
Two most distinct types of slot machines are single line and multiline slots. In single line slots, the machine has just one line of reels, usually with 4 or 5 wheels, while in multiline there are a number of reel lines. Multi line slots are a little bit more complicated because winning combinations may play out across a number of lines; when you win, the machine will draw you how the symbols combine together and calculate the win automatically. Sometimes you don't win anything at all, and sometimes multiple combinations award you with relatively big winning money. Paylines can be different. They can be vertical, diagonal, zigzags and what not.
Jackpot is also a feature peculiar not for all slots. If the slot machine has a jackpot it means that a certain amount of each additional bet is added to the jackpot. So the jackpot becomes bigger and bigger with every bet. Jackpots can reach several hundreds of thousands dollars. A certain winning combination hits the jackpot, and the lucky gambler collects everything that the ones before him left behind.
Since slot machines appeared they have been played with coins. Online casino slot machines are no exception to that rule, even though bets might differ slightly. Indeed, as well as with all small wager games, there are top bets - they're known as table limits in table games. Unlike the table games, slot machines don't involve any decision on the player's part and so aren't threatened by game management systems because of their fixed odds; the bet limits are more of a traditional thing than anything else.
Software slot machines (as well as the digital ones) are equipped with a random number generator which is what actually plays the game. This methodic allows very fair and precise balancing without actually hurting neither the players' interests nor the casino revenue.

Meet the man who beat the slots.
Slot machines pay on a random basis, but what if you could improve the payout a little? Would you do it? Tommy Glenn Carmichael would and did.
Tommy is now 53 and he can be said to have spent all his life inventing different devices to cheat slot machines. His first device was a kind of a top-button joint. By the way, for this device he was sent to prison. After the release Tommy began to invent new kinds of devices for cheating slot machines. His next invention was a slider, a guitar wire. He inserted it into the machine, which released coins form the hopper.
Later the slot machines were not any longer mechanical, they were computerized and as a result there appeared a need for a new device. Tommy found a manufacture who showed him the inside of a slot machine. It was enough for Tommy. His new inventions was a light want that blinded the sensor of the slot machine and as a result got winnings. Other gamblers liked his invention and he had a lot of customers, which allowed him to earn up to ,000 a day. Now he could afford the most expensive cars and several houses.
But as known good things can’t last forever. Tommy was caught using his invention in one of the casinos. While charges from that incident were later dropped, he was caught under similar circumstances in Laughlin and later Atlantic City. By this time, authorities had tapped his phone and recorded conversations with other cheats who used his device. He served three years’ probation and lost both homes. He has been banned from entering any casino.
