Different Types of Slots Online For British Players in 2024

When you signup or login at the best slots casino you'll usually find that the slots category is the largest and also divided into different categories. This is where the filter function can be very useful once you know the type of slot games you are looking to play. Below are the main categories you'll find in 2024 after registration.

Classic 3 Reel Online Slots

Classic slots are three-reel games with a basic design and the ones you will likely have seen in pubs. They are retro style games with symbols such as fruit, gold bars, or lucky 7s. They can be very simple games to play, and many don't have additional features like bonus spins, scatters, or wilds. These online slot machines are often called fruit machines and there are plenty of great choices with huge jackpots waiting to be won at new slots sites. The Play'n Go Joker Freeze slot is a great example.

5 Reel Video Slots

There 5-reel games are the most popular type available. They will have 5 reels with 3 or 4 rows of symbols, and they are themed on everything you can imagine. They feature stunning graphics, storylines, animations, video, and great soundtracks. Video slots are engaging and the addition of bonus features like wilds, scatters, multipliers, and bonus games, make them more engaging and fun.

3D and Live Slots

3D slots have been growing in popularity. They play the same way as video slots, but the graphics are done in 3D style to really make the game come alive. They also include bonus features and stunning visuals. Some of the greatest titles to try in 2024 include Gonzo's Quest and Turning Totems. You will also have the opportunity to play the best live dealer slots if you looking for a more immersive and interactive gaming experience in 2024.

Progressive Jackpots

Progressive jackpots are for the big jackpot hunters. The jackpots up for grabs in progressive slot games can payout in the millions. The RTP percentages can be on the low side, but with the chance to become an instant millionaire, it's worth it. The progressive jackpot can be triggered randomly or through a specific combination of symbols and a percentage of every bet goes towards the jackpot prize which keeps rising until it's won. There are 5 reel and 3 reel progressive slots and the most popular titles include Mega Moolah from Microgaming and Mega Fortune from Netent.

Megaways Systems

Megaways are a new category developed by Big Time Gaming. They use the Megaways slot engine which gives players a larger number of ways to win, often as high as 117,649 in some titles. Each reel displays a random number of symbols after each spin usually between 2 and 7. The more symbols the great number of paylines. These are high variance slot games and there are plenty of great titles to choose from at top online casino sites.

Penny Slots

Penny slot games let you bet small and enjoy all the action and fun of real money slot games without breaking the bank. It doesn't mean the games are any less, far from it, they still have quality graphics, great soundtracks, and the chance to win big cash jackpots.
