Our Top 10 Best Online Demo Slots to Try in 2024

At Slotozilla, we’ve got thousands of the best free online slots to enjoy. Yet, if we had to narrow it down to our favourite 10, then check out our table below.

Variety of Slot Machines for UK Players

Not all online slots are created equally, there is a diverse range to choose from, with varying rules. It depends on what you prefer, with some slots offering higher volatility, whereas others provide more exciting gameplay. With that in mind, here are the main types of slot machines you can play on the internet.

• Video slots: A type of slot that uses a digital screen to display symbols and the gameplay. The reels typically number at least 5, and the paylines vary from 10 to thousands of ways to win. Volatility can also vary depending on the slot you are gambling on, from low to high.
• Classic slots: Made famous by one-armed bandits in pubs, classic slots typically have three reels and one to five paylines. These slots are popular because of their simplicity. The symbols are often nostalgic ones, such as cherries, bars, oranges, sevens and lemons.
• 3D slots: 3D slots offer players three-dimensional graphics and animated gameplay, for a more immersive gaming experience. A more advanced way of playing slots, 3D slots often have interactive elements such as mini-games and fun storylines. The graphics and audio are always high quality too.
• Progressive slots: A type of slot where the jackpot increases each time the game is played without being won. With many progressive jackpots, there are multiple tiers of jackpots such as mini, minor, major and mega. The most famous ones are Mega Moolah and Divine Fortune.
• Megaways slots: Developed by Big Time Gaming, Megaways slots give players up to 117,649 ways to win on the reels. The majority of Megaways slots use at least six reels and include cascading reels, multipliers and bonus features. The best Megaways slots are The Dog House Megaways and Ted Megaways.
• Multi-payline slots: Multi-payline slots give players even more chances to win on the reels. Paylines can run vertically, horizontally, diagonally, or zigzag and players can adjust their bet on each pay line. Normally, a higher number of symbols are displayed compared to classic slots including scatters and wilds.

Slot Functions

When playing slots, there is a lot of jargon to understand. That’s why our in-house team has made a glossary of all the slot features:

• Bonus rounds: A special feature which comes in all shapes and sizes. The most common type of bonus rounds are free spins. Yet other online slots have pick-and-win rounds, wheel of fortune, expanding wilds, mini reels and cascading reels. To trigger, you normally need to land scatters.
• Autoplay: If you want to play slots in cruise control, you can use the autoplay function. Simply select how many spins and the stake you want to bet on the rounds and hit the start button. From there, you do not need to spin the reels manually, as everything has been programmed to be automatic.
• Gamble feature: A type of mini-game that you unlock after a winning spin. Often, it’s a double-or-nothing option, where you either have to guess the colour of a card (red or black), a high card challenge or just a coin toss. Players love the gambling element as it gives them a chance to increase their winnings.
• Win both ways: In a traditional slot game, paylines are paid from left to right. However, with a win-both-ways slot mechanism, you can win from either the left-right or right-left. This doubles your chance of winning after every spin. The most famous type of win both-ways online slot is Starburst.
• Pick and click bonus: A type of bonus feature normally triggered by landing at least three or more scatters anywhere on the reels. You’ll then be given the option of picking an item related to the slot theme. In these items, you can win anything from instant cash prizes to free spins and extra bonus games.
• Respins: Respins are triggered by landing symbols or combos on the reels. If you get respins in the base game, one or more reels are spun again for free, giving you a chance to land more combinations and potentially increase your winnings. You can also get respins in bonus games by filling up the metre or landing specific symbols.

Symbols

When playing online slots at online casinos, symbols are the graphics displayed on the reels. These will be relevant to the slots theme. For example, on Big Bass Bonanza, the symbols are fishing-related.

The goal is to match the symbols on the pay lines to score wins after each round. Yet, there are special symbols such as the scatter and the wild.

Scatters

Whether you gamble at an online casino or play free casino slots with bonus rounds, the scatter plays a big role in the overall excitement of the game.

The scatter is a special symbol that typically triggers the bonus feature when you land at least three anywhere on the reels. In addition, it will be relevant to the slots theme. For instance, in the Book of the Dead, the scatter is the book, with Sweet Bonanza, it’s the lollipop and in The Dog House, it’s a paw.

Wilds

The wild is another special symbol when you play online slots because it substitutes for every other symbol so you can make winning combinations. Depending on the slot, wilds may or may not substitute for the scatter.

Because of its substitution qualities, the chances of winning are much better for the player. Also, they add an extra dynamic that makes online slots more exciting. Wilds have many varieties, including regular, sticky, walking and random.

Sticky Wilds

When wilds are sticky they are fixed in place until the free spins round ends or a certain number of spins finishes. Sticky wilds give players a better chance of making winning combinations because the wild is constant. In bonus rounds, sticky wilds may come with multipliers or trigger respins.

Walking Wilds

Walking wilds move in a specific direction after each spin so you have less chance of making winning combos than stickys. In classic and new online slots, the direction the walking wilds move can be right to left or left to right, adding a dynamic to online slots.

Random Wilds

Wilds are added randomly anywhere on the reels at any given time. This is a contrast to regular wilds where certain combinations or symbols must be met to trigger. The element of surprise is what makes random wilds popular with players. In the bonus features, wilds are introduced unpredictably.

The Most Popular Slot Themes in 2024

Online slot themes are a big part of playing slots on the internet. Everyone has their favourite, and many online casinos will provide the option to filter games by theme.

The most commonly played slot themes include Ancient Egypt, fishing, TV/Movies and sports. Below, we’ve constructed a table with the most popular slot themes this year.

The Best Software Providers for Free Slot Games

Thousands of software providers create games at online casinos, with free slots as an option. Game developers use state-of-the-art technology to produce games with exciting gameplay and bonus features. Below, we cover the biggest software providers in the industry.

• Playtech: With hundreds of slots to enjoy, Playtech’s library is diverse. Yet, if you love movie-themed slots, then Playtech is famous for DC Comic slots such as Batman and the Penguin and DC Justice League.
• IGT: IGT is a globally renowned brand that started making slots for land-based casinos back in the 1970s. Since then, it has produced a slew of online slots such as Cleopatra, Triple Diamond and Monopoly.
• NetEnt: Founded in 1996, NetEnt is one of the most reputable software providers in the gambling industry. The gaming library has over 200 slots, including popular ones like Starburst, Dead or Alive 2 and Gonzo’s Quest.
• Microgaming: On all 800 Microgaming slots, you can play the demo version. It’s a big brand in the industry, having started way back in 1994. The top slots the company produces are Book of Atem, Game of Thrones and Immortal Romance.

Playing Free Mobile Slots: A Quick Lowdown

You can download an online casino app, where you’ll be able to claim no deposit free spins offers. From there, you can even play slots for free if you want to learn the rules before using free spins or gambling any of your own cash.

Also, everything is instant play, so no download is required. If you wish not to download an app, you can also enjoy free slots at a mobile casino in your preferred browser like Chrome.

Free Slot Games vs Real Money Slots

Free slots are perfect if you are looking to learn the rules of the game and practise strategies. Yet, there is one major downside – it’s not possible to win real money.

If you are a beginner, it’s advisable to play free slots. Yet, when you are ready to play, there are plenty of online casinos for UK players to play the best slots online. If you’re undecided, we’ve made a table on the comparison of free slots against real money ones.

Why Should I Try Free Slots?

Free online slots give you the chance to play for fun and explore new games without the need to risk your own money. In addition, you can test out strategies and enjoy bonus features such as mini-games and the pick-and-click bonus.

Nevertheless, the main drawback of playing free slots is that you’ll win no real money. When you are ready, many casino sites will give you free spins, and you can even partake in tournaments to win cash prizes.

We’ve listed all the best free slots you can try today, as well as the finest software providers on the market. So start playing a few on our site, Slotozilla, and when you’ve mastered the rules, take the plunge, claim a welcome bonus and start playing for real money!
