Right after its development in 1895, a slot machine became very popular with casino gamblers. And since those times its popularity is only increasing each year. But today slot machines are much more advanced and developed than those first examples. Unlike the first mechanical devices, which had special spinning cylinders with signs on them, almost all of the modern slot machines are operated by a computer chip. Modern software allows using all the possible scenarios, graphics and sound effects for the slot machines. All that makes modern slot machines very entertaining, and that is possibly one of the reasons why so many people play slots at the casinos.

With all these technical abilities many casinos started to make slot machines that replicate classic casino games, like roulette, blackjack and poker. But don't be confused with these machines. Although there is an illusion that you can affect the game's outcome by making special bets or choosing cards in video poker, in most case these games are operated by the usual slot rules. This means that no matter what you do during the game, it won't increase your chances to win. The possible house edge is programmed in a computer chip that controls the game, and it cannot be changed by any mean.

So as long as the house edge in the slot machine is constant, it is necessary to choose the best paying slots machine of all the available machines in the casino's hall. How can you differ the best paying slots from all the others? In most cases the slots of Vegas style have the so-called slot candles. These are the lights on the top of each slot machine. The color of the slot candle usually shows the denomination of this particular slot machine. Usually colors are the following: red light for the nickel slot machines, yellow light for the quarter`s slot machines, and the blue one for the dollar slot machines, but it is better to find out the color differences at the casino. Of course, the more you bet - the more you can win. So with the blue colored candles slot machine you will be getting bigger sums of money.

Another important thing to consider when you are choosing the best paying slots machine is the pay out rates. The house edge programmed in each machine defines how much money this machine returns to the player. The usual value of the pay back rate in most of the casinos is about 90-98%. That means that in a long term (for a million bets, for example) from each $1000000 the slot machine will return about $980000 (if the pay back rate is 98%), and the casino will take $200000. Probably the lowest pay back rate is at the English casinos as they allowed having as low as 70% pay back rate - the usual number is 78%. You have to keep that in mind, if you are going to play slots in Britain.

In your search for the best paying slots, you can figure out the pay out rate of the slot machine by its pay table. If the machine has more combinations with smaller wins, then probably it has a higher pay back rate.

And whatever you do, playing slots at the casino, you need to keep it slow - always know when to stop the game - otherwise you can lose a lot of money.
