Progressive Slots Developers: Microgaming, Playtech, NetEnt and NextGen.

Bonus Slots

Video slots can be an exhilarating journey into a world of luck and strategy. With a range of exciting features like wilds, free spins, scatter symbols, real money bonus rounds, and multipliers, real money videoslots that you can find at these top paying UK casinos offer more than just spinning reels.

Here are some top sites where you can choose from a wide menu of video slots games: bet365 UK, VideoSlots, 10bet, GrosvenorCasinos, Winomania and new Pub online casino.

What are Videoslots?

Video slots are the modern evolution of the classic slot format, featuring advanced graphics, sound effects, and animations. These games typically offer five or more reels and a large number of paylines, sometimes going into the hundreds or even thousands (often referred to as ways to win).

Video slots frequently include special symbols such as wilds and scatters, which trigger bonus features like free spins and mini-games. The themes of video slots can range widely from ancient civilizations and mythologies to popular culture, movies, and TV shows.

Video slots often come with higher volatility and RTP compared to classic slots, due to the additional features and ways to win. These games are great for players looking for engaging gameplay, immersive themes, and a chance to win big.

Example of Video Slot: Who Wants to be a Millionaire Megaways is an example of a video slot. This game offers high volatility and an RTP of 96.24%. With 6 reels and an astonishing 117,649 ways to win, it offers advanced features like Megaways, scatter symbols, and wilds.

Classic Slots vs Video Slots: What’s the Difference?

Online casinos present a vast array of games to cater to the diverse tastes of players. Among them, slots are incredibly popular due to their simple gameplay and potentially significant payouts. Slot games come in various forms, but the two most common types are classic slots and video slots. This article explores the differences between these two slot types to help you make an informed choice for your gaming pleasure.

The main differences between classic slots and video slots are in the complexity of gameplay, graphical representation, and bonus features.

Classic slots offer a straightforward, nostalgic gaming experience with few bonus features, making them great for beginners or those who prefer simplicity. In contrast, video slots provide a more interactive and feature-rich gaming experience, with advanced graphics and numerous bonus features.

In terms of payout, video slots usually come with higher volatility and RTP due to the additional features and ways to win. However, keep in mind that with higher volatility, wins are less frequent but potentially larger.

Understanding Return to Player (RTP)

The Return to Player (RTP) is a critical factor in selecting which video slot to play. The RTP represents the projected percentage of total bets that a specific game will return to players over a significant number of plays. This measure is typically calculated over one million plays or more.

However, it’s crucial to remember that the RTP is an average and not guaranteed each time the game is played. For example, a game with an 85% RTP does not mean that a player can expect to win an average of £0.85 for every £1 staked during a single playing session. RTP can vary widely due to statistical variance and differs from game to game.

Grasping Game Volatility

Volatility, often referred to as variance or dispersion, is another critical concept in video slots. Provided by Game Suppliers, volatility is a measure of the frequency and size of payouts that players can expect from a slot game.

A slot with low volatility will reward players with frequent wins of lower to medium amounts. In contrast, a high volatility slot, though not paying out as frequently, offers gamblers the chance of much larger wins.

Now that we understand these concepts, let’s dive into our list of the top 10 exemplary online video slots.
