A vampire-themed slot and a NetEnt classic, Blood Suckers has a very high RTP at 98%. This is much higher than the average of 96% that we see most slots fall into.

Different types of online slots 6j353a

When browsing the slot selection at an online casino, you may notice that they fall into different categories, such as megaways or progressive jackpots. The best online casinos will offer a range of slot genres, categorising them by their type, provider, or in order of most popular choices.

Understanding each of these categories is invaluable, as you’ll be able to find exactly what you want and where to look for it. With that in mind, here’s a look at every type of slot on the market for you below.

Classic Slots vs. Video Slots 5t1mw

If you were to think of a stereotypical slot machine in Vegas, you’d most likely be thinking of a classic slot. They involve three reels and offer comparatively simple gameplay compared to video slots. Classic slots come with limited paylines, a simplistic design, and give players uncomplicated entertainment, which is perfect for beginners. 

Video slots, however, have extra levels, bonus rounds, more paylines and more reels - making them ideal for players who want a bit more from their gameplay.

Slots with themes and storylines 51682x

Themed slots and slots with storylines have grown in popularity over the years due to their immersion and entertaining gameplay. The most popular slot themes include those that are Ancient Egyptian-themed, Irish-themed and fishing-themed.

A few examples of each of these themed slots include Book of Dead by Play’n Go for the Ancient Egyptian theme, NetEnt’s Finn and the Swirly Spin for the Irish theme, and, of course, the Big Bass series by Pragmatic Play for the increasingly popular fishing theme.

Slots with bonus rounds 55154q

Bonus rounds are in-game features that offer players free spins or a side game with exciting extras. There are different ways of activating bonus rounds. For example, in Big Bass Bonanza, the bonus round is activated after landing three scatters, which takes you into a free spins round.

If you’re ever confused, check the information (i) button on the slot to see how you can activate the bonus rounds.

Bonus buy features are also present in select slot games in certain territories, giving players the chance to activate the bonus game for a fee. The Dog House Royal Hunt offers a bonus buy as an option, with two options set at different prices. It’s common for there to be two or more choices for the bonus buy feature; one activates the standard bonus, and the others amplify the bonus.

Multi-line slots 1t2j3c

Multi-line slots offer several paylines compared to one-line slots, which only have one payline available. Here’s what you can expect from different slots and their paylines.

• Three reels, as seen in classic slots, offer one to five paylines.

• Five reels, used in video and more complicated slots, can use from nine to thousands of paylines.

• Progressive jackpot slots give prizes that grow with each wager, meaning there is no prize cap. Each progressive jackpot can have varying paylines, but tends to match video slots and have a higher amount.

3D Slots 67343i

A 3D slot will have implemented quality graphics and visuals to give the players the illusion that they are truly 3D. Whether it's characters jumping out or symbols exploding, players love 3D slots for their immersion. 

Megaways  2t6m5q

Unlike most slots, which typically use fixed paylines, Megaways alter the number of ways to win with every spin, meaning they are potentially the best-paying online slots. There are different symbols which increase the variability of the slot, giving the players a larger number of ways to win. A common feature found in a lot of Megaways slots is the avalanche feature, where symbols ‘drop’ into the reel at random.

Mobile slots 61mm

Some slots are designed with mobile compatibility in mind, either adjusting the gameplay or the features to run smoothly for lag-free, on-the-go gaming. There are, however, mobile slots that are made exclusively for mobile online casinos and created for the best gameplay possible for mobile gamers.
