Slots are categorised into different types based on their themes, mechanics, and payouts. These games have existed for over a hundred years, evolving by one component after the other. Today, we have 3D slots with cascading and tumbling reels for increased winning chances. The following are the different types of online slots you’ll encounter at casinos.
The ‘classics’ are so named because they’re the very first generation of slots. These machines were simple, coming with one payline and symbols like fruits, bells, bars, and sevens. From the 1900s to the late 90s, these classic slots dominated pubs and brick-and-mortar casinos. They had no bonus rounds until Reel ‘Em was produced in 1996. They form the bedrock of the more advanced slots we have today.
With the advent of the internet, video slots became the next big thing following classic slots. They capitalised on classic slots to incorporate more reels, bonus rounds, and more paylines. They’re commonly characterised by having a reel set of five reels and three rows. Paylines were up to twenty, creating a more fascinating gameplay than classic slots. Examples of a video slot are Gonzo’s Quest and Starburst.
Megaways slots are some of the most popular slots sites in the UK. These games come with expanding reels and an increasing number of paylines, up to 117649 ways. The number of paylines can also increase to more than 256,000 ways. An example is the Dog House Megaways.
Classic and video slots worked with a spinning reels mechanism. This means reels will spin and combinations will form to give a payline and earn a payout. However, cascading/tumbling reels changed the game with a new mechanism of clearing out symbols as they formed combinations. This means you can have multiple wins from a single play as long as matching combinations form.
Slingo is a combination of bingo and slots, where players spin a reel to generate numbers. The numbers are then marked in bingo style. When you complete the winning lines, you’ll get a payout. Some of these Slingo games have in-game bonuses such as free spins, wilds, and multipliers. Examples of Slingo games include Starburst Slingo and Tetris Slingo.
Progressive jackpots are such that players wager certain amounts, and a portion of the wager is accumulated in a prize pool. As more players wager, the prize will continue to increase. The jackpot win will be randomly triggered by a lucky win. Once the jackpot win is recorded, the prize resets, and the jackpot prize starts accumulating again. Examples include slots in a Lucky Rush tournament. Progressive jackpots can take weeks to months before they’re triggered.
Unlike progressive jackpots, daily jackpots give you cash prizes daily. The prize pool amount on daily jackpots is usually less than that of progressive jackpots. You’ll find these types of slots in categories such as ‘Must Go Jackpots,’ ‘Must Drop,’ and ‘Daily Drops.’
To pick the top slots websites in the UK, the following are factors you must take into consideration.
Before you think of picking a slots website, you must first assess the collection of slots in its games library. The casino should have a wide array of slot categories, ranging from classics to jackpot and Slingo. The games should have an info tab where you can get an overview of the game before you play. It should highlight the volatility, RTP, in-game features, max payout, and the number of paylines available. These slots should come in different themes and must be compatible with your mobile devices. If you’re particular about the software providers supplying the slots, check through the list of software providers available.
It’s important that the site has free online slots with no deposit required. These can include demo games or free-to-play slots where you’re given free spins to win real money. Demo games help you learn the rules and mechanics of a new slot before you wager with real money. You can test every feature of such games, come up with strategies, and maximise your winnings.
The site you’re playing with should have welcome bonuses and promotions tailored to slots. These will include cash prizes, free spins, reload bonuses, and cashback rewards. However, you must watch out for the wagering requirements and expiry dates to make sure they’re favourable.
The payment option you select for deposits and withdrawals will contribute to how seamless your experience gets at the casino. Slot sites deposit methods should be instant and convenient, and withdrawal methods should be fast and without fees. Some of the payment options you should watch out for include credit/debit cards, e-wallets, voucher cards, bank transfers, and cryptocurrencies.
The customer support service should run 24/7 and should involve multiple channels such as live chat, email, and phone support. Live chat is especially favoured as you can initiate a chat and talk with a representative within a few minutes.
The conventional way slots work is that you spin the reels and form matching combinations on a payline. Winning combinations are typically taken from left to right. However, with the many genres of slots developed now, the following are some of the game mechanics you may encounter.
The wide variety of slots can have you confused about strategies and helpful tips to explore when playing. The following are some of the best tips to use before you start playing.
Although you might get comprehensive information about the slot on an info tab, it’s best that you put what you’ve learnt to practice with the demo games. You’ll learn faster when you practise with demo games, helping you get familiar with the rules, mechanics, paylines, RTP, and volatility. Once you understand the basics, you can begin to come up with strategies to manage your finances and make better decisions.
High RTPs mean you’ll get more returns in the long run, compared to slots with low RTPs. Also, the more volatile the game is, the less likely you’ll experience frequent wins. However, high volatility games give the highest amounts when they finally start paying. Low-volatility slots give more returns, but the cumulative amount will not be as high as that of higher volatilities.
You can use free spins to earn real money from slots. Take advantage of them when they’re offered as promotions in your selected casino. However, be sure to check that the wagering requirements are easy to meet before you take the bonuses.
Stay within your budget, whether you win or lose when playing slots. Chasing losses can lead to you exhausting your bankroll without realising any wins.
This article has covered everything you need to know about slot sites and their offering in the UK. Each site we reviewed is certified safe, holding verifiable licenses from reputable gambling authorities. They come with thousands of slots, which you can play on your mobile devices or PCs. You’ll never get bored with the vast genres and themes available. From practice with demo games, you can develop strategies to become an excellent slots player with good wins to show for it.
