How we rate slots – what we look out for

When it comes to slots, we created criteria on what we look out for when rating an online slot game. So, we highlighted how we put our slot review together with some key points below.

Free games and demo options

Demo games are an excellent way to enhance your slot strategy. We would look through the operator and find a free play option that you can practice before spending your real funds. If the game offers a demo play, we will rate it higher than a slot that doesn’t. It’s always a great idea to start with free slots before you do spend because it will also allow you to get to know the ins of the game and prepare your skills beforehand.


When it comes to different slot jackpots and online slots, we know that each will have its own paytable. We would look at the paytable, which shows what each symbol on the slot machine is worth and which is the most rewarding if you were to spin those symbols. We also recommend slot machines that have smaller jackpots and a lower variance, as these are more likely to be won. Different online slots have different amounts to win, so it’s up to the customer what they’re looking for. If they’re all high jackpots, they may be more attractive to the potential customer but less likely to payout if they’re a higher variance game.

Jackpot size

As we mentioned, we also recommend slots with a smaller jackpot size and lower payouts on symbols. If you’re new to slots and are not chasing the higher amounts, then the jackpot sizes may not be a big deal. Bigger jackpots can be enticing, and many slots have these, but they tend to have a higher variance which means that although the payout is higher, wins are less frequent and you could quickly blow your whole budget and never land a win. Smaller jackpot slots tend to have a lower variance, so the payout amounts will be less, but wins will be more frequent. They’re often a better place to start if you’re new to slots.

Return to Player (RTP) rates 

Each slot machine is different, so we researched the symbols, features, soundtrack, themes, and graphics they have to entice the customer. They also have a different RTP rate meaning the percentage of all wagered money the slot will pay back, on average, to the player over a certain time. It’s better to go for a game with a higher RTP rate, so check the percentage the online casino offers before you start playing.

Top developers covered- latest developer news

It’s important to have a look through the different slot game developers in the US to see how they’re making changes and improving the casino game industry. Our reviews always consider what these developers offer their customers. So, we listed a few to discover what makes them stand out.

IGT (International Game Technology)

IGT or International Game Technology is one of the most popular slot game developers in the US. They were founded in 1975 and are a huge force in the slot game industry, with their video slots making up the majority of those available in US casinos! They have a huge portfolio of casino games accessible in the US and worldwide, which makes them a reliable choice.

Some of these popular slot games include licensing deals with board games and tv shows, including Monopoly, Star Trek and Cluedo. So, if you’re looking for a developer that has a wide variety of options, IGT might be the right developer for you.


You may recognize this Japanese company as they have a history of producing the best-known arcade and computer games. Konami has expanded over the years to developing gaming entertainment in different fields, including casino games and in particular slots. They didn’t establish a take on slot machines until 1997 when there weren’t many competitors, so it could grow quite rapidly and expand across America and in Australia.

Konami’s slot games have a similar theme which is usually inspired by their Asian heritage. It is a popular theme for slot games, including Ancient Dragon, China Mystery, and Rising Sun. Their range of slot games is quite impressive, with nearly 400 available to play and counting.

Genesis Gaming

Genesis Gaming is another option of a popular developer to choose from. It doesn’t have a long history like Konami or IGT, as it was formed in 2008. But, it has had years to grow as a slot developer and is a top choice for online casino users. Genesis Gaming built their games on different structures, including Flash and HTML5, to be easy to access by players on whichever device they choose to play with. Some of their popular online slot games in the US include Ragnarok, Orion, Gods of Giza and Temple of Luxor.

Slots tips and tricks – how to win 

If you’re new to online casino games and want to know how to win at slots machines, then look no further, as we have put together a list of tips that could be useful! There is no guarantee that your outcome will always be a win, as you will need to practice the slot online and find a machine that works in your favor. But, these tips and tricks would be beneficial for any player to try after reading this review.

Start with a budget

This tip is extremely important for any individual that hasn’t played slots before. You may feel like you’re on a winning streak, but things could all change, and you could lose more than you bargained for if a budget is not a top priority. We recommend starting small and seeing where the lower-priced spins will get you. Budgeting is important for any casino game, so make sure you stick to it or risk getting caught out by enticing slot offers and jackpot claims.

Check out the developers

As we mentioned in this review, we looked at the top developers of online slot machine games in the US. It’s essential to see the competition and discover what they offer their customers who choose to play their slots. As the gambling world continues to expand in the US, there is always room for operators to improve their site’s development regarding the look and feel of the online casino. Customers can check the RTP percentage for each game before they play it and decide if the games are what they’re looking for. In addition, players can have a look at customer reviews of these developers to see what other individuals are truthfully saying about the games and avoid losing out.

Use bonuses

At TheGruelingTruth, we recommend that online casino players take advantage of the site’s bonuses they have on offer. There may be a welcome bonus to use that is risk-free and an excellent way to see the ins and outs of a certain game. These bonuses might not always be accessible, but when they are, you can make the most out of them and potentially generate returns! Most casinos in the US will allow you to sign up for notifications on when these bonuses and promotions are available to use. This can be through a text message or email subscription

Understanding the slot machines

Before you start playing these online slots, we think you should consider understanding how they work. Demo spins are a great way to practice these games before spending real money. And once you know how a game works, you will have the upper hand. Slot machines are based on a random number generator (RNG) software and will decide whether the spin will win or not from when you press play. Each machine is different and will have different odds, so it’s up to you to choose which one is right for you and will benefit your slot strategy in the long run.

Conclusion – check out slots online

Overall, we think using an online casino to play with slots is a great idea for new and familiar gambling enthusiasts. At TheGruelingTruth, we would recommend you try out the slot games to see if they could become your new favorite way to enjoy your time online. Choosing a slot game with a jackpot that isn’t too large and has a lower variance, is an excellent way to begin playing slots, as lower variance slots have better odds.

Our review looked at a range of top operators that allow you to use their online casinos to play these exclusive games. We think you should consider finding a casino that has slot games with free plays or offers a welcome bonus with free spins.
