Low wagering slot sites are a blessing for gambling fans. They allow you to convert your bonus winnings into real cash much more conveniently. With that in mind, here are the best low wagering slot sites for 2020:

Slot Casino Welcome Bonus Wagering Highlight Casino Rating Safe Link T&C

The true value of a slot bonus can only be determined by checking the conditions. With a high wagering requirement, it can often be difficult to complete the required playthrough before the bonus expires, meaning you would lose any winnings you made with it. Low wagering slot sites, on the other hand, come with much more convenient conditions, so you can get your hands on your winnings much more easily.

The Best Online Slots: Top Slot Machines to Play Online

The Top Slot Jackpots You Can Claim

Progressive jackpot slots are a highlight of the game category. Whilst they give lower average payouts, they offer the biggest prizes you can win in online gambling. With a portion of all wagers on jackpot slots added to a prize pool, the jackpots can quickly build to life-changing sums of money. Want to play for big money? Here are the top jackpot slots you can play online:

  1. Mega Moolah – Guinness record for slot jackpot. (18,915,872.81€)
  2. Mega Fortune – NetEnt’s biggest jackpot payout. (17.81€ million)
  3. Gladiator Jackpot – UK player won the biggest jackpot. (2.4€ million)
  4. Jackpot Giant – Record jackpot was won playing on mobile. (£4.5 million)
  5. Hall of Gods – Features 3 jackpot prizes; Mini, Mini, and Mega.
  6. Age of the Gods – One of six Age of the Gods Playtech Jackpot slots.
  7. Pink Panther – Features Minor Pink and Major Pink jackpots.
  8. Beach Life – Playtech’s biggest slot payout (£6.2 million).
  9. MegaJackpots Cleopatra – Jackpot pooled with IGT MegaJackpots slots.
  10. Man of Steel – Top-Rated Playtech DC Superheroes jackpot slot.

Some jackpot slot games are linked. For instance, Playtech’s Age of the Gods slots all contribute to the same prize pool. You will also find that many progressive jackpot slots feature a range of jackpot prizes. For example, when you trigger the jackpot in Mega Fortune, you spin the wheel to win either the Rapid, Major, Or Mega jackpot. Slot jackpots are triggered randomly when you play. Yet, generally speaking, the higher your wager, the better your chance of hitting the jackpot. Still, there are some notable exceptions to the rule. Take Microgaming’s Mega Moolah slot for instance. On October 2015, a lucky Brit scooped a record-breaking £13.2 million with a bet of just 25p.

The Best Online Slot Games to Win

Online slots are games of chance. They require little skill to play, and there is no sure-fire strategy to ensure that you win. That said, there are ways that you can improve your chances of winning at top slot sites. You will need to do your research and check a lot of details. For your convenience, we have done the research for you. Here are the online slots with the best odds to win:

Gameplay: Information You Need to Know

Slots are among the easiest fun games you can play online. If you have never played online slots before, rest assured that it is easy to get started. Perhaps the hardest part is deciding which game to play. There are thousands of online slots available, and they can be separated into various categories. Classic 3-reel slots have a retro vibe, reminiscent of classic fruities. They typically feature fruit machine symbols, such as cherries, lucky 7s and bars. You will most commonly find 5-reel slots when you play at top slot sites online. Video slots with 5 reels offer many more paylines and ways to win, making for a more fun experience overall. They also boast a range of special features, with free spins and bonus rounds offering plenty of excitement and chances to win big. Video slots are not limited to 5 reels either. There are games with more reels and rows, expanding the winning ways.

The Variety of Games Found at the UK's Best Slot Sites

Online slots come in a wide range of themes. Among the most popular themes, you will find Egyptian, superhero, Asian, vampire, fairytale, and Irish slots. Video slots boast sharp graphics and beautifully designed symbols to capture the theme. They also offer imaginative features and ways to win. There are also 3D slots, which boast the most advanced graphics, creating even more immersive gameplay. You will find many branded slots online. These games are based on popular TV shows, hit movies, and other pop culture themes. The symbols and bonuses are authentically themed, and they are very popular with players.

Slots can also be categorised by whether they offer a jackpot. Jackpot slots can feature a fixed maximum prize. This can be won by filling a payline with the highest paying symbol, or through a bonus feature. Whilst progressive jackpot slots continue to build each time they are played. The prize gets bigger and bigger until a lucky player triggers the jackpot. The jackpot will then reset and continue to build once again.

Slot Rules & Basics

To play slots online, you should start by choosing the size of your wager. Slots come with the option to adjust the coin size and bet level, so you can adjust the bet size to suit your budget and style of play. Some slots have a fixed number of paylines, whereas others are adjustable. For the most exciting gameplay and more chances to win, we recommend playing with all paylines active. Once your bet is set, you simply click on spin to play the game. If you line up a winning symbol combination, you win a payout according to the paytable.

The most basic rules are the same across all online slot machines. So, you know how to play any online slot. Yet there are some special rules that you should also familiarise yourself with. Most slots feature an autoplay option. This allows you to select a number of spins to play automatically. This gives you fast, uninterrupted gaming. The quick spin option can also increase the pace of the game, by reducing the time the reels take to spin.

There are also some special symbols that you will encounter. Wild symbols are a common feature of slots. They substitute for other symbols, helping to complete winning symbol combinations, in turn, boosting your chances of payouts. Scatter symbols can offer payouts without needing to appear in sequence on a payline. You will often find that scatter symbols are the key to unlocking extra bonus rounds and free spins features. Multiplier symbols boost a winning payout by a specified amount. You can also find stacked, sticky, and bonus symbols among the more innovative online slots.

Slot Game Software: Best Providers for UK Players

There are many software houses that develop online slots. The game selection you will find at an online casino depends on the software providers the operator partners with. For most players, the software provider is extremely important in determining the best online slot sites to play at. The software determines which games you can play at a casino site. Some operators are powered exclusively by a single software provider. Others select their slots from a wide range of leading developers. Slots from different developers vary in terms of quantity, quality, innovation, RTP, and features. Here is the top slot casino software:

NetEnt are one of the best slot developers. Their slots are renowned for their innovative features, high-quality graphics, and favourable RTPs. NetEnt player favourites include Guns N’Roses, Starburst, and Gonzo’s Quest. Playtech is another leading casino software provider that is popular with UK players.

Slot RTP – The Meaning of Return to Player

We have referred to RTP several times in this online slot sites guide. In this section, we will delve further into the concept and explain the details you need to know. RTP stands for Return to Player. It expresses the amount of all wagers placed on a game which are returned to players as winnings. It is a good way to assess how profitable it can be to play a particular slot. For instance, a slot with 98% RTP will theoretically pay out £98 for every £100 wagered on the game. This is more favourable than a slot with 94% RTP, which will pay out £94 for £100 wagered. Therefore, the slots with the highest chance of winning are those with a high RTP.

You should note that the RTP is calculated over many thousands of spins. As such, you can see higher or lower returns when you play. Yet it is a good overall indication of how the slot pays out. Another term that goes hand-in-hand with RTP is house edge. This expresses the percentage of wagers that are kept by the casino as profit, rather than paid to players. In essence, the opposite of RTP. So, when a slot RTP is 97%, the house edge should be 3%. Top slot sites will list the RTP of a game within the rules. Plus, UK-licensed online casinos are independently tested to check that their games pay fairly.
