Some of the most common slots bonuses are classic deposit match bonuses, free casino spins, free casino money, free play bonuses, wagering bonuses and special package promotions. Casino promotions and welcome bonuses come in many forms.
The type and generosity of the welcome offer will depend entirely on the size of the online casino, how long it’s been operating and what it can afford.
Some slot focused casinos will design offers based solely on online slots and give players a selection of slots to choose from. In this section, we’ll be delving into the top casino promotions which are targeted to online slot enthusiasts:
As the name suggests, these types of promotions are catered for online slot lovers. The number of free spins awarded in the welcome bonus tends to be generous, especially when combined with a deposit bonus. These free spins are usually able to be played on one particular slot.
The casino will specify which online slot is eligible for their promotion and in some cases, you’ll have the liberty to choose from a number of top online slots. Be sure to visit the terms and conditions first, as from there you’ll discover the wagering requirements and any capped winnings from your free spins.
No deposit bonuses are some of the most sought after bonuses by casino players, for obvious reasons. The online casino bonus rewards players just for opening an account as a token of appreciation for choosing them.
No deposit free spins are probably the most preferred casino promotions relating to online slot enthusiasts. Players feel at ease knowing the fact that they're able to spin the reels without having to commit any funds.

The terms and conditions will list the online slot games available to use the free spins on, so be sure to read through them before you accept the bonus as this means you will be fully aware of any wagering requirements.
Differing from a regular welcome bonus, Welcome Spins to be a bit more generous than a regular welcome bonus, as they are dedicated just to spins. For instance, some online casinos offer free spins on all NetEnt games in their free spins package while others will only have a couple of games to choose from. Some of the best-known games making their way in free spins bonuses include: Starburst, Blood Suckers, Dead or Alive, Rich Wilde and The Book of The Dead.

Slots come with all sorts of features – from a classic three reel game that you’d recognise from an antique game, up to a state of the art video slot with extra mechanics, there are so many ways to win and play. Here are the best slot features that you’ll find in the online casino world.
A typical characteristic of classic slots. The well-known symbols consist of cherries, lemons, bells and BAR-symbols, each with their own assigned value from low to high paying. Fruit machine slots also use card suites as winning symbols. These are where it all started – and tend to feature in a lot of slot games even when they’re brand new!
Progressive Jackpots have been around since the brick and mortar casinos, making it a highly volatile yet rewarding feature. By having a bunch of slot machines lined up together, the collective loses will be pooled together into a communal jackpot, making one lucky player very happy once the jackpot it hit! Most online casinos offer progressive jackpot slots, and often the jackpot is put together by players across multiple casinos – making for huge winnings!
Wild symbols can really switch up your game - with a wild symbol able to replace any other symbol in play, they can line up combinations that you would not have gotten otherwise! When lining up your symbols on the reels, wild symbols can either let other symbols work together for set wins, or trigger their own special rounds, depending on the rules of the game.
Scatter pay symbols pay out winnings no matter how they land on the reels. These make for exciting gameplay, with potential wins all over the game, and when combined with other symbols they can make for huge wins.
There are plenty of parts that make up a slot game - these are the most important parts of a slot game and what make it tick.
Coins are used to place your stakes on the slot machine you’re playing on. The coin size determines the value of your stake and how much your wins the payout. The higher the coin size you place on your stake, the higher your payout will be. Most games will give you the option to switch between currency and coins.
Volatility is usually stated within the review of the slot game when you check its instructions. The higher the volatility, the more the symbols will change on the reels and the higher the payout will be once the player does manage to land a winning combination on the reels. The lower the volatility on a slot, the more frequent the wins and stability of the symbols are, but the less the player will get paid out.
The RTP percentage, or Return to Player, is the amount over an unlimited amount of time that a player can expect to get back when playing a slot. The RTP will always be stated before playing the slot game. RTP can range from anywhere between 90% to 98%.
Paylines are the winning combination that can be made on a slot machine by lining up or matching symbols. There can be a few or there can be as many as over a thousand – it depends on the developer and the game mechanics.
| Name | Release Date | Provider | Reels | Volatility | Rating |
|---|---|---|---|---|---|
| Book of Dead | 2016 | Play'N GO | 5 | High | 5 |
| Wolf Gold | 2017 | Pragmatic Play | 5 | Medium | 4.5 |
| Gonzo's Quest | 2010 | NetEnt | 5 | Medium | 4 |
| Bonanza Megaways | 2016 | Big Time Gaming | 6 | High | 5 |
| Fire Joker | 2016 | Play'N GO | 3 | Medium | 4.5 |
There are several Ways To Win features, one being specific to one game provider. These are ways of lining up symbols in the reels which can lead to more wins for the player.
Like the name suggests: this feature allows the player to strike up matching combinations using both ways on the reels. Whereas normally players are only able to utilise combinations made from left to right on the reels, the Win Both Ways features goes from right to left as well, increasing win chances.
The 243 Ways To Win was the first one of the features to be developed and implemented on online slot machines. Like the name gives it away: slot machines with these features allow the player to land a winning combination in up to 243 different ways, increasing chances to win and landing a higher payout as well. This extended the classic left-to-right formula that was around on slot games in years prior.
A massive upgrade from the original 243 Ways To Win feature. 1024 is always played on a slot machine with 5 or more reels, making it possible to combine different symbols into this huge amount of winning paylines. Common on most online slots, you shouldn’t have any difficulty finding a game that offers you these options.
Perhaps the crème-de-la-crème of the Ways to Win features. This slot technology has been developed by the software provider Red Tiger Gaming and adds an additional reel on the slot, making for huge potential wins. This feature is limited to specific games right now, but more are popping up as time goes on.
Real money slots are where the excitement is – your big wins can be added to your bank roll and withdrawn, means you get the full benefit of the great gameplay of slots that you wouldn’t in free play. Some of the biggest bonuses of real money slots are:
Some more benefits of playing at real money online slots are, that unlike card games or table games in general, where you may go through multiple rounds before obtaining a good hand or play, slots can provide you with a win from a single spin. That’s a highly appealing prospect for many gamers, as you can bet the minimum on a spin and receive a pay-out for a winning combination occurring in the game.
Slot games are known for having exciting themes and gameplay running through them, but there’s also the possibility of winning huge jackpot payouts, too. Jackpot slots are favoured by many players because of this prospect. Imagine placing a minimal wager and receiving thousands in a jackpot pay-out after just a few spins – it’s rare but it does happen!
For UK players there are plenty of real money slot options. With some of the top casinos in the online casino sphere operating in the UK, they can be guaranteed not only a safe, secure, and fun experience, but also some of the top slots with the best gameplay. With bonuses available in many UK online casinos, as well as stringent regulations from the UKGC, you're guaranteed to have a good time.
Things changed for a lot of online slots in the US when the law was reformed. Now there are hundreds of slots available, and depending on which state you are in, playing real money slots in the USA is legal and easy. For example, gamblers in NJ have plenty of NJ online casinos to pick from which allow them to play slots for real money. Local laws may affect your online gaming experience, but if it's legal for your area then you have plenty to pick from!
Canada has hundreds of options for online gambling - with plenty of casinos not only specialising their offering and bonuses to Canadians, but also allowing you to play in English or French, and use Canadian Dollars, your real money online slot options are almost endless. With some of the top slots available at Canadian online casinos, with potential huge wins at your fingertips, you can expect a great time.
Once you’ve made yourself comfortable with online slots, perhaps you’ll want to try and incorporate some sort of strategy into your gameplay, too. Of course, there’s not much that can be done to really influence the outcome of a spin on a slot. However, you can minimise your losses and get to grips with managing your money by remembering certain tips and putting them into effect.
As noted earlier, playing slot games isn’t the same as playing blackjack or baccarat for example, where different plays can be used. Instead, games in this category are created with a random number generator (RNG) that controls the fairness of the slot. This means that every spin has a randomly decided outcome when you hit the button to start the game.
Check out what the pay-outs for each symbol combination are. See what sort of bets you’re able to place when playing it. Look into the way(s) that you can trigger the different special features of the slot. The more you know about your chosen slot game(s), the better your chances are of remembering what’s going on when you play it. Furthermore, if you know the betting range on offer, chances are that you’ll be able to tailor your bankroll more effectively.
A couple of final things to remember to take a look at are the RTP rate and the volatility level of the game you’re playing. These can dictate to you how often you can expect to win and the strength of the pay-out you can expect to receive.
If you start out with smaller bets, you can discover more about how the game operates and you’re not risking too much of your balance at the same time. You need to be playing with funds that you can’t afford to lose in the first place anyway, but starting out by placing the minimal bets will allow you to better get to grips with how the slot works and how often the features will trigger.
Try some out in free play demo mode first, then choose one or two that speak to you more.
With so many different types of slots, features and casinos, it can be quite daunting to decide from where to start. We took some time to answer our readers' most common questions below.
What is a free spin in the best online slots?
Free spins are a set number of spins that a player can make without needing to bet with their own money. They may receive 10 free spins as part of a bonus, for example, and they can use those free spins to play a certain game without needing to stake their own money.
Which slots have the best odds of winning?
When looking for the best odds of winning, you want to find the slot with the best RTP. This is the "Return to player". Basically, it's a percentage value that shows how much you would get back for every bet statistically. You're not guaranteed to get that same amount all the time, but as a general rule a higher RTP is a higher chance of winning. There isn't a special trick to winning, but a higher RTP is a safer bet.
Which slots have the best RTP?
Some slots generally average around 96% RTP, but some can go as high at 97-98%!
What kind of slots are the top online slots?
Although all slots follow the same premise of spinning to match symbols, there are variations in online slots. Video slots are almost like a videogame, and have interesting effects and game play. Classic slots are more similar to what you'd find in your everyday casino. Jackpot slots take a percentage of each stake, from every site that they're found on, and put it together into a cumulative jackpot which any player has a chance to win.
