How do free slot machines work?

Here’s how slot machines work! Every Slot Machine has a chip inside, called the Random Number Generator (RNG), which does high speed mathematical calculations in the background. However, the chip stops and a random combination is displayed, precisely when you pull the handle. Well, this is how online slots work, except for the fact that there is no chip, but a software program that does the random number generation.

How to play free slots online?

You can find countless websites that let you play free slots online, but unless you know the basics right, you may not be able to enjoy the thrill that comes with every spin. So, to make you the undisputed master of reels, we bring you more clarity and a list of some of the must-knows for free slot enthusiasts.

Reels and Paylines

The most basic form of traditional slot machines used to have three reels, but the modern day machines usually have more than that. The same goes for online slot machines and you can find them with different symbols and varying number of reels.

If you aren’t familiar with what reels are, then you ought to know that reels are the vertical lines in the slot machine that appear like columns. So for the player to win, three or more symbols need to line up on the payline. How much a player wins depends on the wager and the underlying value of the symbols. So, we strongly recommend that you go through the relevant Pay Table before you get started.

Typically, the game starts when the player hits the ‘Spin’ button, which is precisely the moment when the reels start moving. These reels generate random numbers in a manner similar to that of the traditional slot machines. The only difference is that the random number generation in the physical slot machine is controlled by a chip, called the Random Number Generator (RNG) chip, while the online slot machines generate random symbols based on a software program.

However, unlike traditional slot machines, their online counterparts do not stick to the traditional rule of horizontal paylines. Instead, there are multiple paylines that you can wager on, and if the symbols appear on your chosen payline, then you win the game.

Bonus Features

Not all online free slots offer bonuses — but most of them do, which makes the game all the more exciting. If you aren’t aware of bonuses, then you are missing out on what’s in fact the real money maker.  Bonuses are a bunch of micro games, within a slot game that only some lucky ones get to chance upon. Usually, these are the hidden treasures within the game which include multipliers, and other inbuilt smaller games that can vary from board games to skill based games or simply include extra spins. So, Bonuses can be widely classified into free play bonuses and free spin bonus. For better clarity, it is recommended that you refer to the particular slot machine’s Pay Table.

High Volatility vs. Low Volatility

Volatility refers to the number of wins and the size of the rewards given out by a slot machine. Some tend to offer smaller rewards more frequently while there are those that seldom let you win, but when they do, the rewards are exceptionally high.  So which one you wish to choose is absolutely a matter of personal choice, but we’d recommend that you look for high volatility slot games. If you are wondering how to figure them out, then high volatility slot games are easy to pinpoint and are the ones that offer most bonuses, because that’s where the money is.  So take a look at the Pay Table to gauge its volatility.

Return to Player (RTP)

Usually, the payout for physical slot machines is between 85 and 98 percent, and online slots also offer a similar payout range, which is known as Return to Player (RTP). Now that you know what free online slot machines are, let’s figure out the various types of free online slots.

Types of Free Online Slots

Fruit Machines

Fruit Machines are synonymous with slot machines in the US, and are one of the most celebrated categories of slot games, that are beginner-friendly. Usually, free play fruit machines don’t have any complex paylines and are easy to operate. Plus who doesn’t enjoy watching some juicy fruits spin on the reels.

Mobile Slots

You can now download secure mobile slots on your android and IoS devices, for an amazing gaming experience. Mobile devices have indeed made our lives easier and when it comes to mobile slot games, they go a step further to offer the same benefits that most casinos do, including the introductory bonuses.

Progressive Slots

These are dynamic slot games, where the jackpot increases in size with every spin. So, progressive slots refer to slot games with a “progressive” or increasing jackpot amount. This amount grows with every player’s participation, as a fraction of the wager goes into the jackpot.

3D Slots

Unleash your imagination and let it go wild with graphic-rich 3D slots that offer an enhanced video gaming experience. No, you don’t need those geeky glasses, but can still feel the objects popping out of the screen, to give you the thrill of a lifetime.

Video Slots

These are the traditional video poker slots that are simple and easy to operate, and come without any distractions. So, if you are someone who isn’t too tech savvy or aren’t a graphics buff, then the regular video slots should be just fine for you, so pull the handle and go!

No Download Slots

Online casinos operate either by requiring the user to download a software (on their computer or mobile), or on a ‘no download no registration’ basis. The latter does not require the user to download anything and enables the user to gamble straight from the browser, through internet.

No Registration Slots

These are slots that let the user retain a higher degree of anonymity by not requiring the user to register.

Free Slot Machines Features

Free Spins

You may either win free spins or may get those as introductory bonuses, but here’s what ‘free spins’ actually mean. A free spin gives the player an opportunity to spin the wheel but without any deductions from the player’s account balance, so these are indeed ‘free’.

Re spins

If you “just missed” the jackpot and seriously wish you had another chance, then you might, but only if you can afford it. Now this type of arrangement is known as a‘re-spin’ and mustn’t be confused with ‘free spins’. We recommend that you seek more clarity on the cost of the re spin, in order to avoid any unpleasant surprises later on.

Wild Symbols

Wild symbols are the bridging symbols, which increase your chances of winning in many ways.  Say, you are looking for 3 monkeys on the payline but get only 2 monkeys and a wild symbol — then guess what? You’ve won because as mentioned earlier, ‘wild symbols’ bridge the gap so they transform into a ‘monkey’ or anything else that can fill in, and favour your chances of winning the slot game.

Scatter Symbols

Scatter symbols help unleash the bonuses and open up a whole new range of benefits for the player.  However, you need to check beforehand whether or not the chosen slot machine offers scatter symbols. Although the traditional 3-reel slot machines seldom offer scatter symbols, but you are more likely to find them on the 5-reel slot machines.


Multipliers multiply the reward that you are likely to receive by ‘X’ number of times, and this can also come in the form of bonuses.

Bonus game

Bonus games are mini-games within the main slot game that few manage to qualify for. These are designed around the main theme of the slot game, and are more interactive.

Shifting Reels

Just like the wild symbol, the shifting reels increase your chances of forming a favourable combination.  The only difference is that the wild symbol is static, while the shifting reels usually shift to the nearest and most favourable place.


Jackpot slots typically refer to progressive slots, which have a ‘jackpot’ that grows with participation. So, each time a player places a wager, a part of it goes into the jackpot. So, these are usually high-ticket bets.

Slots Popular Themes


The good old fruit-themed slots seem to be a favourite amongst slot gaming enthusiasts. This was in fact the very first theme around which the traditional slot machines were built.


A bunch of crocs and lions make slot games a lot more interesting and add the fun element to it, which enhances your gaming experience.  No wonder animal themed gaming slots continue to be popular.


The Egyptian theme continues to be a hot favourite amongst online slot players, and takes the player into a wonderland, hoping for some magic with every spin.

How do you pick a winning slot machine?

This isn’t really possible, but there’s definitely something that you can do in order to increase your chances of winning a jackpot. Look out for high volatility games with more bonuses listed on the pay tables. Also, by simultaneously placing your bet on multiple paylines, you increase your chances of winning.

Can you win money playing online slots?

Online slots are quite similar to the slot machines in casinos, except for the fact that they run virtually, at the click of a button. So, yes, you can win money playing online slots, but only if you get lucky.

Can casinos tighten slot machines?

The slot machines in casinos generally make money by retaining a small percentage of what you gamble and give out the rest in the form of rewards that generally range between 85 to 98 percent.  So, when a casino buys a slot machine, the casino has the discretion to choose its cut off percentage and communicate the same to the manufacturer who would then program the machine accordingly.  So the answer is yes and no! While this is possible, most ethical casinos would not do that because they need to give a full disclosure of the payouts to the concerned regulatory authority.

How are slots programmed?

The slots are programmed to generate random numbers at lightning fast speed, and this is made possible with the help of a chip or software program called random number generator. Besides generating the random numbers, the developers also program the slot to retain a small fraction of the sum gambled.


Above listed is a comprehensive guide on slot machines, but we strongly recommend that you do your own research to confirm the legitimacy of your preferred online slot. Also, look up for one that permits your preferred mode of payments, as some of the above listed slot machines also offer payments through bitcoin.
