What Are Free Spins?

Comparing free spins is essential to choosing the ones with the best value. No deposit free spins are among the most popular bonuses and appeal to most players.  You will come across many types of free spins bonuses. Two common types of free spins are those you receive as part of a welcome bonus and promotions for existing members. Some free spins bonuses require you to make a deposit. You can then use them to play qualifying slot machines. Other types include players receiving several spins on specific titles as part of a promotion. Finally, there may be regular offers and no deposit free spins that boost the new slot's popularity. The benefits free spins offer are many! You can test your skills and improve your technique, try new releases, and have free fun while doing so. In addition, free spins allow you to play without risking your own money. 

Free Spins On Registration No Deposit

Many online casinos provide new players with free spins upon registration. Once you sign up at such a casino, you receive several spins without having to deposit. The only obligation to claiming the no deposit free spins is to sign up at the site. There will be wagering requirements, of course, as with many other bonus types. Once you satisfy them, you can withdraw your free spins winnings. In all probability, you may want to deposit and continue playing at the site, as you can also claim a standard deposit bonus to sweeten the deal. 

No deposit free spins are free games on slot machines that you can use without depositing at the casino. No depositing free spins are readily available and often part of the welcome bonus package. They effectively entice players to register and play for longer at the casino and deposit real money later. No deposit-free spins are available to play real money games without depositing any cash. No deposit-free spins are subject to cashing-out limits that vary with each casino, so check the terms before you sign up. 

No Wager Free Spins

No wager-free spins are growing in popularity, and it isn't hard to understand why. No wager free spins bypass expensive wagering requirements altogether so that you can access your winnings straight away. As a result, you won't need to invest more cash to get directly to your free spins winnings. With no wagering free spins, you'll never have to worry about paying more to cash your bonus. Plenty of UK casinos offer wager-free spins. They typically form part of a welcome bonus, regular promotional offers, loyalty perks and rewards. Most zero wager bonuses are for free spins. You can also refer to them as no wagering, no deposit free spins, and zero wager free spins. Whichever name, they all come with no wagering requirements. No wagering free spins are among the most popular as they provide winning chances for free.

Welcome Bonus Free Spins (On Deposit)

One type of promotion is where free spins go out in conjunction with a welcome deposit bonus. However, you need to make sure these bonuses are worth it as such bonuses usually have higher wagering requirements. In many cases, the rollover requirements for the deposit bonus and free spins are the same, with 25x to 35x typical rates. Many online casinos offer regular deposit bonuses with free spins to appeal to slot players. They may give free spins to players at once, or perhaps they go out over a while. It isn't uncommon to receive ten free spins a day if the number is considerable; that way, you can utilise them bit by bit, and they will last longer. You will find such bonuses have wagering requirements, so try to understand the terms before accepting the bonus gift. You can read about the wagering requirements below. 

Mega Value / Higher Value Free Spins

There are all sorts of free spins out there, so it's always best to read the small print. Mega or higher value free spins are those with the lowest wagering requirements, or no wagering free spins, with zero wager requirements. Seeking out the best value free spins is crucial. For example, it's better to have 25 free spins with 10x wagering requirements than 100 free spins with requirements of 70x. It's also vital that the slot titles included in the offer have a reasonably high RTP payout percentage; otherwise, their value diminishes. 

Different Slot Providers Free Spins

The market is full of casino software providers; however, many of them are renowned for their free spins offers. They include Netent, Microgaming, and Play N Go. Read on to discover why they are among the best for free spins. 

Netent Free Spins

Netent Free Spins are attractive perks you can receive at various casinos supporting Netent software. These particular freebies are available on multiple slot games, including the trendy video slots and any other classic slot machines. Not all platforms offer you that chance to play with additional free spins. Still, most of them will greet new players with special bonus packages, which are ultimately welcoming gifts after successfully singing for entertainment. Moreover, there are several Netent free spins hidden within slot machines waiting for you to trigger. You can use the free spins to practice your slot skills and verify if your luck matches the minimum requirements. Without the need to provide more funds, the free spins will usually be available after your deposit, providing even more funds to keep you playing. These handed out free of charge are even more appreciated than any other promotional value of a similar sort.

Microgaming Free Spins

Microgaming online casinos offer some of the best bonuses and free spins offers out there. Microgaming vets the casinos it provides licences to, and they all adhere to high standards. That essentially means that players can rest assured that the slots and other casino games they're playing are both safe and fair. Online slot machines are the best Microgaming casino games out there and the most popular online casino game, more generally. Every year thousands of players attempt to hit the jackpot playing their favourite slot titles. When it comes to slot software providers, they don't come bigger or better than Microgaming's. Most UK casinos offer free spins for the most popular slot machine titles. Therefore, you're sure to get good value. 

Play'n GO Free Spins

Play'n GO slot games are regularly available as part of a signing up bonus offer. The majority are free spins or a combination of deposit and free spin bonuses. There are welcome bonuses that include Play'n GO free spins, and the developer is pretty good when it comes to promos. The free spins are available only for Play'n GO casino account holders. Depending on the casino game, the free spins may need wagering requirements. Play'n GO games are available in most online casinos, with most of them are on these pages. The majority of UK online casinos offer free spin bonuses, and you have the opportunity to test your tenacity on their best games. The free spins typically come with a wagering need, and a cap on the maximum wins you withdraw. It is wise to go through the terms and conditions for the specific online casinos, but expect to find a wagering prerequisite for the free spins you win up to 40 times.

Free Spins Wagering Requirements Explained

The wagering or rollover requirements for free spins correlate with the total amount of your winnings, usually expressed as a multiple. That means if the wagering requirements are 20x, then you need to wager 20 times your winnings before cashing out. Suppose you have 25 free spins with wagering requirements of 30x. Once you play through the free spins winnings, you can pull in £20 in winnings. To cash out, you need to wager at least £20 x 30, which is £600 in all. Once you wager the £600, you can then cash out regularly and withdraw using a banking method of your choice. Forward-looking online casinos are starting to offer no wager bonuses alongside traditional deposit bonuses with wagering requirements.

Nevertheless, welcome bonuses are essential to attract new players and keep them engaged on the site for long. Regulars can look forward to deposit bonuses, reload bonuses, free spins, cashback offers, free money, free chips, or bonus credits. In addition, there are multiple regular weekly or seasonal promos. The problem is players often mistake the bonus as free credits to play games at the casino and win real money.
