The slots machines are one of the most popular games in the online casinos, they are called in different ways as for example Poker Machine and Fruit Machine.   

The first slot machines were built around in 1890 and it has been one of the biggest attractions in the casinos.  

The mechanism of the slot machine is based on a horizontal roll fixed on a central axle.  

On every face of the roll a symbol is represented that in base to the combination, with the faces of the other rolls it determines the value of the win.   

The slot machine can have three rolls or to be multiple (more than three rolls, so that to have increases of combinations).  

The traditional slots normally pay only the wins on a horizontal line, called line of payment.   

With the advent of the video slot the builders have invented the multi-line videoslots where the wins are counted on more lines.   

These new videoslots generally use 5 spools and gives the possibility to use 25 lines, to activate a line you have to insert a token (or a credit), this means to activate all the 25 lines you have to insert 25 tokens.   

If in this case, one of your wins is on a line not activated the win is not received.   

In the multi line videoslots the possibilities of winning are very high, but on the contrary of the traditional videoslots with one line, you need to know the number of the lines to activate for being able to be awarded a rich prize.  

A lot of Videoslots offer some bonuses on the deposits to attract new players, these bonuses consist on the percentage of the increase of your deposit, or of a bonus of entrance during the registration.  

Some videoslots have a progressive jackpot, this means that the value of the jackpot is not based on your combination (to get the jackpot in the Jackpot Deuces for instance you need to have a Royal flush of diamonds; in the Supajax four jacks and the joker card Supajax) but on an amount that grows up until a fortunate player wins it.   

In both the games described above to access the possibility to win it needs bets with 5 credits.  

To play with the slot machines it is very simple, you insert coins (or of credit if you are on the online slot machine), you decide the amount of your bet, you pull the lever of the “spin” (or click the spin button) and you observe the wheels that turn.   

At the end of the “mixes” if you have been fortunate and you have made a good combination you will receive the reported jackpot to your combination (every real slot machine or online slot machine has a chart where are explained the winning combinations to the correspondent prizes).  

In the slot machine game a good strategy is in to individualize those with higher payments, where you will have greater possibilities of profit; keep in mind that the slot machines can not use systems of probability seeing that the game is totally causal.
