Types of Slots

No matter what design or number of reels there are in a slot machine, there are basically two variations of slots games: straight and progressive. There are different variations of these two, but generally these are two types that you will find in any casino, be it online or in real world. The main difference between straight and progressive slots is the way the jackpot is calculated.

Progressive slot machines have a constantly increasing amount of jackpot, which results from the number of coins you have played. In case you are playing a linked slot machine, the amount of jackpot is comprised of the over number of coins played in the entire network (and there can be hundreds of machines there). The amounts of jackpot you can win playing progressive slots are impressive. On the other hand, the chances of you hitting the jackpot are very low, because there are many players in the same network competing for the prize.

Straight slots in that sense are much simper. You play all by yourself and the sum of jackpot is predetermined by the machine. Your chances of winning are fairly high if compared to progressive slots, but the jackpot itself is very low.


Slot Machine Odds

No matter what symbols you see on the reels of the slot machine you are playing, the only thing that matter is how many symbols there are on each reel. And how many reels there are in the machine. The less reels there are and less symbol on each, the higher is the probability of your win.

Let’s take that you have to get three lemons in the payline to hit the jackpot. Taking the case that you are playing a 3-reel slot machine and there are 18 symbols on each reel, the chances of you winning are:

All possible combinations in the machine: 18 x 18 x 18 = 5,832
The probability of hitting the jackpot: 1/5,832 (1 in 5,832)

When playing a 5-reel slots game with the same number of symbols per reel a simple math calculation shows that your chances of hitting the jackpot are:
1/ (18 x 18 x 18 x 18 x 18) = 1,889,568 ( 1 in 1,889,568 )

As you can see, the chance of winning dramatically decreases by having just two additional reels in the machine. Sometimes, the more reels the machine has, the higher is the jackpot. Yes, it may be quite thrilling but be sure to do the math first and see what are your chances with each slot machine.


History of Slots

The first slot machine with three reels in it was invented in 1895 by car mechanic Charles Fey in 1895. This machine was called the Liberty Bell and had diamond, spade and heart symbols on each reel, with an additional broken liberty bell symbol, from where the machine got its name. The machine became so huge, that Charles Fey wasn’t able to keep up with the demand even when his own state banned gambling. Many have offered Fey to sell his production and distribution rights, but he refused. And that has led to the creation of Operator Bell, which was actually a modification of the Liberty Bell with the famous fruit symbols introduced to the reels.

In 1930’s the industry has moved away from the original iron design that made the machines very heavy, and introduced wood boxes. During that period, there were also new designs introduced to the layout of the machines to make them more attractive and memorable.

But it was only in the mid 1960’s when a fully automatic slot machine was introduced, that was able to operate and perform payouts without the help of an attendant.


Slot Machines: Online vs Offline

When slot machines have first made it online, they are so different from what you were used to in land-based casinos, that online slots seemed like a completely new game. But today, with the development of the Internet and online casinos, you can’t actually think of a difference between real and online slot machines.

Both online slots and their land-based predecessors operate using the same RNG principles. So the game itself is completely identical. Whether you push the spin button online or pull the handle at a land casino, there will be exactly the same process going on inside the machine, and your odds of winning will be the same too. Online casinos give you the chance to play free slots by using virtual coins. Unless, you choose to play paid online slots, where the coins have the exact same value of real casino coins. Another pro-online aspect is that you can play slots for as much and whenever you like, when with real slots you’ll have to travel to a casino.

Playing slots online will cost you less than playing land-based slot machines. Why is that? Because you don’t have to spend any on traveling to a gambling site and can enjoy slots right at your home. Another aspect is that online slots have higher payout percentage compared to real slots. This is because online casinos have far lower costs of operation than their real-world counterparts and can offer their players higher chances of winning.

One really big difference between online and offline slots is that you won’t be offered a free meal when playing online. But online casinos have made steps to substitute this advantage and reward regular players by other means. For example, some online casinos have points accumulated with your every game, which you can then redeem as casino coins. Other online casinos even offer real merchandise for the points you have accumulated.

In what concerns progressive jackpots online casinos cannot yet compare to the tens of millions of dollar jackpots paid out at offline casino. But still there are some really big wins available online too, with nearly 2 million jackpot being hit at an online progressive slot machine once. Smaller amounts of money (tens of thousands) are won at a regular basis, with numerous online slots being linked in major progressive jackpot networks. The main advantage of online casinos regarding progressive slots is that you receive your win in a single installment. In land-based casinos a big jackpot is usually divided in smaller sums that are paid out on a timely basis.

Guide To Playing Progressive Slots

If you want to hit it really big and get a jackpot that will change your entire life, you have definitely given a spin to progressive slots once or twice. Progressives are probably the only casino game that offer you the chance to hit a really big win (we are talking about millions here) for quiet a small bet amount.

Progressive slots were first introduced in the early 80’s when slots games manufacturers started using microprocessors in slot machines. That’s when they’ve decided to add a feature of a constantly increasing jackpot that would result from the number of the bets placed.

The real breakthrough with progressive slots came in 1986 with the advent of Megabucks — a whole network of slot machines at various sites that all shared a single jackpot. This caused really big jackpots to be accumulated because now there were hundreds and thousands of players contributing to the amount.

Since then, progressive slots have become one of the most played casino games both online and offline. Today, numerous online casinos payout million dollar jackpots on a regular basis.

The idea behind progressive slots is very simple. With each coin placed in the machine and each spin of the reels, there is a percentage of your bet added to the jackpot. On the other hand, the payout percentage in progressives is much lower than in ordinary slots. For example if 5% of your bet are added to the jackpot, this means that the payout is less than 95%. Adding some house percentage from the casino itself will land us with less than a 90% payout.

The key to winning in progressive slots is placing max bets. Why? Because virtually all progressive slots, whether online or land-based, only payout the jackpot when you bet the maximum number of coins. Imagine the disappointment when you hit the winning combination and get nothing in return just because you’ve placed a small bet.

And always keep in mind that playing progressive slots is pure entertainment. If you have a sole purpose of hitting a big jackpot, than you’ll be very disappointed. Have fun while playing the game and you’ll be a winner with every spin.
