Find the Best New Slot Sites

When looking for the best new online casinos, you need to consider the following factors.

Easy Registration Process

Look for sites that have a clear and simple registration process to create an account using your basic information. Additionally, Pay & Play and many crypto sites won’t require you to create an account at all.

Friendly Interface

A user-friendly interface can help you enjoy all the different games by making it easy to navigate to your favorites. Look for sites with a search option as well as the ability to filter games by type, provider, bonus features, and more.

Best Promotion for New Players

The welcome bonus is another factor to consider when picking a slot site. Look for Free Spins and Match Deposit deals. These bonuses can help you get acquainted with the different games at the casino. Do check the wagering requirements though.

Quick Withdrawals

The best slot sites will offer a range of safe and secure banking options with fast withdrawal times. There will always be some casino processing time to verify your request. Crypto and eWallet options are usually nearly instant once verification is complete.

What do we include in our slot sites rating?

There are several factors to consider: how do we rate online slot games. The next is the most important.

Licence

We consider a licence as one of the most important factors in our ratings. Having a licence guarantees that the casino operates to certain standards including providing fair gameplay, RNG games, standard verification procedures, and other equally important features.

Bonus codes

Many bonus offers require players to input a code. These codes are a series of numbers or letters that you must enter to qualify for the bonus. We check that these codes are readily available.

Return to player rate

The RTP or return to player rate indicates the amount of money players might win back when they wager on a particular slot. The industry average is an RTP of 96%, meaning that theoretically, for every $100 wagered, the player can expect to win $96 back over an extended period of play. We check the range of slot RTPs at each casino.

Hit frequency rate

Every slot has a hit frequency rate, which tells you how often that slot is likely to land a win, of any size. This is usually given as the percentage of spins that will provide a payout.

Slot Providers

We check that each casino offers games from a range of top-quality licensed developers.

Players choose TOP slot sites as usual

What players think about a site makes the difference between what we rate as a TOP site and one that is just acceptable.

Gamblers’ feedback is important

Players’ feedback is important to other players and the casino alike. It provides information on how the casino works, which features it offers, and any improvement that can be made.

Payment methods

Being able to offer an array of payment methods is paramount. The more methods available the wider an audience a casino will have.

Crypto enthusiasts can deposit as well

Nowadays it is also important to offer cryptocurrency payment methods. Crypto enthusiasts can withdraw and deposit without going through a verification process. Also, payments are made immediately.

Doesn’t block user accounts and funds

Many players choose online casinos that claim they don’t block user accounts or funds. However, all players must still adhere to the casino’s rules.

Highest RTP slots pros and cons

Let’s look at the advantages and disadvantages of playing on the highest RTP slots.

High returns for bettors

A high RTP implies that the casino has set a lower house edge. This increases your chances of winning more often.

Easy withdrawal of funds

Casino operators guarantee straightforward withdrawal methods as with high RTP slots payments could be more frequent.

Casino reduces the size of welcome bonus

One downside of offering high RTP slots is that the casino may cut the value of its welcome bonuses.

Long wait for customer support reply

Because of their popularity, some slot sites offering high RTP games have customer support teams that can be slow to respond. Check the customer support reply times before signing up.

Best online Casino slots FAQ

What does a slot’s volatility mean?

The volatility or variance level tells you how likely or unlikely you are to land big or small wins. A high volatility slot doesn’t pay out often, but when it does, that win can be huge.

What is a progressive jackpot?

Progressive jackpots accumulate in value whenever a slot is played. Some slots are single games, others are multiple slot machines linked together.

What is a paytable?

A paytable is a chart that shows how much you can win on a bet.

What is a payline?

The payline is the line that extends from one end of the slot window to another. Whenever the reels stop spinning, icons on each payline must match in a specific order.
