Our Online Slots Review Process
There’s a massive variety of best online casino slots regularly being launched in the industry. It’s important to us that we review these based on several key factors. We try out each of these games for ourselves with both real money and bonus funds so that we can give you an accurate overview. You’ll also be able to find reviews on the most popular slots of all time in our catalogue.
Mechanics of the Game
We’ll tell you the min/max stakes you can wager, the number of bet levels, paylines and reels. We’ll also let you know the combinations to watch out for that will deliver those all-important wins. As well as our opinion on the in-game bonus features and how well the slot works on a range of mobile devices.
Theme and Soundtrack
We take into account both of these important slot game factors. An annoying and repetitive soundtrack can either make or break your session, so we’ll always let you know our honest thoughts on this. As well as the type of slot theme and the quality of the symbols and overall graphics.
RTP and Volatility
You can rely on us to give you this important information clearly. We also test out each of our recommended online slots to show how fast they’ll play through wagers and provide a ratio of potential wins. As well as reporting to you the house edge which our experts calculate and how often you can expect to get a chance of winning.
Each of our slot reviews states the max win available and the combination of wager amount and symbols which you’ll need to aim for to achieve this. This saves you time reading through in-game information and trying to figure out complicated pay tables for yourself. We’ll also add in our expert thoughts on the max win and if this offers value for money.

Bonuses for the Best Slots to Play Online
Some slot-focused casinos will design offers based solely on online slots and give players a selection of slots. This section will delve into the best casino bonuses for online slot enthusiasts. Keep in mind these bonuses won't be available to be played with every casino game.
We recommend you read the terms and conditions of each promotion before playing:
- Free Spins Bonuses;
- No Deposit Free Spins;
- Welcome Spins.
Classic Free Spins
As the name suggests, these promotions are catered for online slot lovers. The number of free spins awarded in the welcome bonus tends to be generous, especially when combined with a deposit bonus. These free spins can usually be played on one particular popular slot.
The casino will specify which online slot is eligible for their promotion, and in some cases, you'll have the liberty to choose from several top online slots. Be sure to visit the terms and conditions first; from there, you'll discover the wagering requirements and any capped winnings from your free spins.
The free spins bonuses are often valid on a bunch of slot games. The most common are: Book of Dead (Play'n GO), Gonzo's Quest (Netent), Starburst (Netent), Wolf Gold (Pragmatic Play), Reactoonz (Play'n GO), Cleopatra (IGT), Book of Ra (Novomatic), Immortal Romance (Microgaming), Big Bass Bonanza (Reel Kingdom), Rainbow Riches (Barcrest), Bonanza Megaways (BTG), 9 Pots of Gold (Gameburger Studios) and Eye of Horus (Red Tiger Gaming).
No Deposit Free Spins
For obvious reasons, no deposit bonuses are some of casino players' most sought-after bonuses. The online casino bonus rewards players just for opening an account as a token of appreciation for choosing them.
No deposit-free spins are probably the most preferred casino promotion for the best slots-to-play enthusiasts. Players feel at ease knowing they can spin the reels without committing any funds.
All you need to do to qualify for a no deposit free spins bonus is register with the online casino as a new player, and you instantly be rewarded with your free spins. The terms and conditions list the online slot games available for free spins, so be sure to read through them before you accept the bonus, as this means you will be fully aware of any wagering requirements.
Like every free cash casino bonus on the market, even the no deposit free spins have some conditions to meet before the withdrawal.
Unlike a regular welcome bonus, welcome spins are a bit more generous than a standard welcome bonus, as they are dedicated to spins. For instance, some online casinos offer free spins on all NetEnt games in their casino welcome bonus package, while others only have a couple of games to choose from.
Some of the best-known names making their way in free spins bonuses include Starburst, Blood Suckers, Dead or Alive, Rich Wilde And The Book of The Dead.
Welcome spins are a perfect way for newbie players to get used to the mechanics of an online slot and an opportunity to get familiar with pay tables, game symbols and pay lines. This will make playing slots online a much better experience for new players!

Here are the best slot games with wilds:

Fun Bonus Games
Bonus games bring a secret extra twist to the best casino slot games. Sometimes, you'll spin symbols that trigger an extra round or a new gameplay mode.

Other Benefits of the TOP Slots
Some more benefits of playing at real money online slots are that unlike card games or table games in general, where you may go through multiple rounds before obtaining a good hand or play, slots can provide you with a win from a single spin.
That's a highly appealing prospect for many gamers, as you can bet the minimum on a spin and receive a payout for a winning combination occurring in the game.
Slot games are known for having exciting themes and gameplay running through them, but there's also the possibility of winning huge jackpot payouts. Many players favour jackpot slots because of this prospect. Imagine placing a minimal wager and receiving thousands in a jackpot payout after just a few spins – it's rare, but it does happen!

Best Online Casino Slots Strategies
Once you've made yourself comfortable with online slots, perhaps you'll want to incorporate some strategy into your gameplay. Of course, there's not much that can be done to influence the outcome of a spin on a slot. However, you can minimise your losses and get to grips with managing your money by remembering specific tips and putting them into effect.
As noted earlier, playing slot games isn't the same as playing online blackjack or baccarat, where different plays can be used. Instead, games in this category are created with a random number generator (RNG) that controls the fairness of the slot. Every spin has a randomly decided outcome when you hit the button to start the game.
Check out what the payouts for each symbol combination are. See what sort of bets you're able to place when playing it. Look into how you can trigger the different unique features of the top slot. The more you know about your chosen slot game, the better your chances are of remembering what's going on when you play it.
Some other suggestions are:
- Don't forget the classics: among the best online slot games, we have a few classics, such as 88 Fortunes, Wolf Gold and Gonzo's Quest. Give them a chance! These games are evergreen and still the favourite games of many players.
- Go for smaller jackpots: some of the best online slot machines have a jackpot to win. Go for the online slots with a minor jackpot to have more chances to win. Gladiator: Road to Rome and Pharaoh's Treasure Deluxe are small-jackpot slots.
- Check the paytable carefully: don't deposit real money and play with the top slots straight away! Take a few minutes to study the paytable. This step helps understand the game and when it is appropriate to raise your bet.
- Aim for the bonus rounds: the most popular slots are famous for their rich bonus rounds. Aim to obtain those combinations while playing. Some of the most popular games for their bonus rounds are Book of Ra Deluxe and Book of Dead.
- Read the reviews of the top slots: we review the best slots to play online. Check out our reviews and the rules of each game to have more chances to win. We share the secrets and best practices to play these games.
