Choosing the Best Online Casino for Slots

Obviously, most online casinos offer a variety of slots, but what is it that makes these slot sites stand out from the rest? Well, here are some other areas that we look at when picking our preferred online casinos:

  • Firstly, we look for quality. The online casino should be second to none when it comes to customer support – which should be 24/7 and include live chat support. There should also be several deposit methods, fast and secure online casino payment methods, fast payouts, mobile gaming and mobile slots.
  • A selection of excellent slot game providers, including NetEnt, Microgaming, Playtech and more. These providers offer hundreds of excellent top-end casino slots and the quality and quantity of providers are often what sets one online casino apart from the others. They should also offer several different types of games such as progressive jackpot slots, table games, video poker, live dealer casino games and more.
  • A safe and secure place to play casino games. The best sites are fully licensed and regulated by top regulatory bodies and encourage players to gamble responsibly with free gambling addiction resources.
  • Welcome bonuses. We look at the size of the welcome bonus and the terms attached to the welcome bonus including wagering requirements so that you can not only use the online casino deposit bonus on a good number of slots but that you can also withdraw bonus wins.

Playing at one of our top recommended online casino sites will offer players a fun experience. These sites will allow you not only to play for real money but also to play for free in demo mode so that you can choose your preferred online slot games before jumping in with both feet and risking your own funds.

These are some of the best video slots that can be found in pretty much all of the best online casinos. However, this doesn’t even include the ever-popular progressive jackpots that can be found at some of the top slot sites. Here is our pick of the top progressive jackpots games:

  • Mega Fortune
  • Mega Moolah
  • Mega Moolah Isis
  • Mega Fortune Dreams
  • Arabian Nights
  • Divine Fortune
  • Jackpot Giant
  • Age of the Gods
  • Everybody’s Jackpot
  • Treasure Nile

Generally, you won’t be able to use free spins or bonus spins on these games, so they aren’t great for those looking to play welcome bonuses or deposit bonuses. However, when it comes to real money slots, the excitement offered by jackpot slots can’t be beaten. With huge progressive jackpots on offer, if you hit the winning spin in the jackpot bonus game, nearly all New Zealand casinos offer their players a chance for a life-changing win.

The Best Online Slots Features

The good thing about online video slots is that they come in all different shapes and sizes – whether you like the classic three-reel slots with fruit symbols, bars and lucky 7s or the more up-to-date Megaways slots with technology and bonus rounds galore. The best online casinos will have a good mix of all the different best online slots so that all players are catered for. What’s more, many online slots sites will also offer even more ways to make these games exciting, with prize drops, missions and slots tournaments and more.

Here are some of the features you should look for when playing slot casino games.

Fruit Machine Symbols

For lovers of old school casino games, there are excellent slots that emulate the classic fruit machine games. These games offer up all the classic fruit symbols as well as bells, 7 symbols and Bar symbols – the higher paying symbols that create the big wins. This is where it all began for online casinos and there is still a love of these games, which will never be lost.

Progressive Jackpot Slots

If you’re signing up with online casinos to win big money, then progressive games are always games to try out! These have been around for years, way before the first online casinos were founded – and they will always remain popular because they offer players millions. Jackpot slots are highly volatile games that take all the money played by players and put it in a communal jackpot – and if the player hits the winning combination, they get the big prize.

Wild Symbols

Wild symbols can come in a variety of shapes and sizes – normal wilds, expanding wilds etc. These are symbols that can really up the game and the wins. Wild symbols replace all other symbols (apart from scatters) and can create even more winning combinations – often with multipliers. In some of the best online slots, wilds can even trigger bonus rounds for even more wins.


This is often the key to free spins and bonus spin rounds – and is more often than not the symbol that casino players will look out for. When you land scatters, the gameplay steps up even more and this is where the real fun starts.

Comparing The Best Slots Bonuses

When choosing between the best online casinos, one thing you look at will be the free spins offers, welcome bonus and deposit bonuses available. In this part of the article, we’ll look at all the different welcome bonus and deposit bonus options that work well for online slots. So, when you open a new account, you can get playing on your preferred online slots straight away. The choices generally include:

  • Free spins deposit bonuses
  • No deposit free spins
  • Match deposit bonus
  • Match deposit bonus plus free spins

Online Slot Reels

Free Spins Deposit Bonuses

The free spins welcome bonus offer does exactly what it says on the tin – it gives slot lovers free spins that they can enjoy on selected slots. Generally, when signing up for a new account, the number of free spins on offer tends to be pretty generous. Free spins and bonus spins offers generally vary between 20 free spins up to 200+ free spins.

It is important to check the terms and conditions applicable to the free spins. For example, what slot or slots are the free spins valid for? What are the wagering requirements attached? How can you settle those wagering contributions (the wagering contributions vary depending on the game you are playing), check to see if winnings are capped etc.

No Deposit Free Spins Bonuses

Basically, these are the most sought-after bonuses of all slots lovers because they give you the chance to play on some of the best online slots without even having to part with any of their own cash funds. No deposit free spins allow players to try out the games and enjoy different slots without having to commit their own money. To claim them, simply register your details at the online casinos offering the promotions, enter a bonus code (if necessary) and you will get them deposited straight into your account. Again, be sure to check the terms and conditions – often the wagering requirements attached to no deposit free spins are higher than standard wagering requirements and winnings will be capped.

Matched Deposit Bonus Offers

These are excellent bonuses not just for slots lovers but also for players that enjoy other games such as table games, video poker and more. With match deposit bonus offers, simply register an account and make your first deposit. This deposit will then be matched by the casino with bonus funds. So, if you deposit $20 you will get $20 in bonus funds. You can then use this bonus money to play whatever games you want. Again, there will be terms and conditions attached including wagering requirements, a max bonus, a max bet that you can make with your deposit bonus funds (usually around $5). There may also be payment methods restrictions such as Neteller, Skrill or PayPal. Also, generally, only cash stakes qualify and wagering requirements vary.

Match Deposit plus Free Spins Bonuses

Some online casinos offer a mix of match deposit bonus and free spins – which is the best of both worlds. Players can make an initial deposit, get deposit bonus funds to spend on whatever games they choose – such as table casino games, video poker, video slots etc and they can use the free spins on the online slot or slots specified by the casino. Always remember to check the T&Cs attached.

How Do Online Slots Work?

Slots vary a lot – some are more simple than others – however, most operate in a standard way when it comes to setting up the game and playing the base game. Here are some things you should know about:

Coins and Credits

When you make a deposit and look to play a game, you actually play the games using coins. The coin size is what determines how much you are actually playing per spin – and thus how much you stand to win. The higher your chosen coin size, the more of your own funds you are spending, but the higher your wins will be.

Game Volatility and Variance

You will notice that most games will be labelled ‘High’, ‘Medium’ or ‘Low’ volatility. Higher volatility games will offer players higher wins less often, whereas Low Volatility slots will offer smaller wins more often.

Return to Player – RTP Percentage

This is how much you can expect to get back from your bets. If a game has an RTP of 96% then, for every $100 you spend, you can expect to get around $96 back in winnings on average. However, this is not guaranteed. Most RTPs are between 94% to 98%. The higher the better.


Most video slots and slot games offer a set number of paylines – which is the number of winning combinations that a player can make on a slot by matching their symbols up. This can vary hugely – with some offering just a few and Megaways slots offering thousands!

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.

Free Online Slots

When you play slots, you don’t always have to play real money slots. Many online gambling sites allow players to enjoy free slots so they can try a game before committing money. We would suggest you play games for free before committing money to a specific slot site. Now, click here to find out what are the best free online slots.

Winning Real Money on Slots at Online Casinos

Free slots aside, you really want to play real money slots as that’s what makes it exciting – the idea that you can actually win real money is the biggest appeal of online casinos. If you want to win big on real money slots, here are some things you need to take into account:

  • How to play the game. If you are new to online slot games, pick easier games to start with to build confidence, then move on to more complicated games if you want.
  • Try out different games. There are lots of different styles of online slot machines. Try a variety of games and styles to decide which ones you like the most.
  • Casino Bonuses. Try out the games which have more slots bonuses aimed towards them. Games such as Starburst, Book of Dead etc will often have free spins offers dedicated to them, so are perfect games to practice on.

Slots are great because they don’t require strategies or tactics. One lucky spin can be all it takes. Just one single minimum coin spin can lead to a big win, which is why many people play slots.

The Best Online Slots Strategies and Tips

So, you want to play slots online for money – and you want the best chance of winning on pokies. Unlike games such as poker or blackjack, whether you win or not is all based on an RNG (Random Number Generator) and has nothing to do with how you play and which strategies you employ. Every spin is random.

The best way to give yourself a chance is to understand the paytable of the game and understand the different types of bets you can place. You also need to know the different bonus features and how to trigger these features. The more you understand your game, the better chance you have of playing successfully. You should also pay attention to your bankroll. Figure out how much you want to play and stick to it. For more chances of winning, go for low volatility games with a high RTP.

We would also recommend starting with small bets to get to know the game before moving on to bigger value bets.

As long as you open a casino account with a variety of slots games and practice playing slots for free before committing your own money, you are best placed to be successful. Check out our list of best New Zealand casinos to start your slot journey!

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.

Can I Use Match Deposit Bonus Offers on Slots?

Yes. You can usually use match bonuses on all different games, including slots. Remember to check the terms and conditions first as there will be a max bet that applies (usually $5). There will also be a max bonus – and the max bonus wagering requirements will vary from casino to casino. There may also be payment methods restrictions, so check the T&Cs carefully. However, these bonus funds can be used on any game of your choice and you can use this to win real money.
