How to choose the best online slots

Online Slots - best slot games online

Time to talk slots: the staple casino game that has been around since the nineteenth century in the form of those traditional 3-reeled slot machines, and arguably the most popular form of casino game online. Thanks to technological developments and the creative minds of several game developers, online slots have become even more entertaining nowadays. Although the principal behind them remains the same as it was with the traditional fruit machines (you have to land on certain identical symbol combinations), the ways of unlocking wins as well as the win potential itself have become so much more exciting when you play these games online! So whether you're new to online slots or you're an experienced slot player looking for the most rewarding ones, keep reading our article below to discover what you can expect to encounter at online casinos today!

Types of online slots

Slots come in many forms these days. You can still find online versions of the traditional slot machine, featuring a 3x3 game with those timeless fruit symbols. Sometimes, these online fruit machines come with additional perks or bonus games to step up the excitement. If you love classic slots re-worked into a more modern online game, we can recommend NetEnt's beautifully designed Fruit Spin slot and Just for the Win's Deco Diamond slot in particular.

Onine slots today are normally based on a particular theme, and you'll find all sorts of themes; there are horror slots, fairy-tale slots, Oriental slots, futuristic slots, slots based on popular movies - you name it, and you're likely to find it! What's more, these days you don't have to stick to the traditional 3x3 format; A lot of online slots feature 5 reels and 3 rows, but there are many slots that also come in a different format altogether, featuring multiple ways to win as well as a different game mechanic, such as a cluster pay mechanic (such as the cute Reactoonz slot) or a swirling reel (check out the recent Finn and the Swirly Spin slot!).

With so much variety out there and so much potential for innovation, we believe there's never been a better time to play online slots. You can now play most slots both on desktop and on any mobile device, as both developers and casinos are optimising these games for mobile.

Online slot developers

Because of the massive popularity of online slots, the number of slot providers or game developers is growing every year, which leads to the release of new slot games every week. But it's important to remember that not all game developers and their online slots are of equal quality and deserve your time and money. Some of our most favourite providers who have proven to be trustworthy by launching high-quality entertaining games with decent payouts are NetEnt, Playtech, Microgaming, Yggdrasil, Play'N Go, Quickspin, and Elk Studios. However, this list is not exhaustive, since there are also some new developers that are coming up with innovative slots that are worth a few spins. In order to discover about new developers and their creations, we recommend you have a look at some of our game reviews at CasinoHawks, because we only choose to review games which we can honestly recommend.

Highest jackpot slots

When you consider which slot to play online, there are many things you can take into account, such as unique bonus features, the quality of the graphics, unusual themes and interesting ideas. But if you really think about it, you'll also admit that in the end, we all play for a chance of winning, and preferably win a lot! If you wish to receive a life-changing prize that amounts to hundreds, thousands or even millions of pounds, you should go for slots with progressive jackpots. There are slot games which are linked to a jackpot that keeps growing as more and more players play it online, and most of them have already turned tens if not hundreds of lucky players into millionaires.

Online slots bets and RTP

Some of the less fun but crucial things to consider when you're choosing online slots are betting ranges, volatility, return to player percentage and hit rates. It all might sound like mumbo-jumbo, but understanding these things can make a lot of difference and save you a lot of money.

Betting range is simply how little or how much money you can bet on a slot. Wider range slots allow different kinds of players with various budgets to try out the slot game and see how it performs before betting more money. We also suggest that beginners try the slots for free to understand the mechanics and payout structure of the slot before risking their own money. You can do this at many online casinos these days; simply browse for the slot in the game browser and choose to play for free.

Hit rate or frequency is used to describe how often a slot machine will stop on a winning combination. Usually, the machines with higher hit rate allow you to win small amounts often, whereas the low hit rate slots can award massive prizes but it can take quite a number of spins to trigger these prizes.

Return to player rate (RTP) is a percentage measurement that tells you how much profit is set for the slot. An RTP of 95% means that the average amount that a player gets back is 95p per every invested £1, but that does not apply to one player, but to all players who bet on the slot. RTP is an opposite of the house edge, or how much money the house will take on average. If the game's RTP is 96.2%, the house edge will be the remaining 3.8%.

Volatility or variance is a ratio of size to the frequency of a slot’s jackpots. The higher the volatility, the more you can win and the more you can lose as it represents a greater risk. Low volatility games sometimes considered a better option for newbies with lower budgets, who don't feel like risking too much.
