how we review slots onlineHow We Write Online Slot Machines for Money Reviews

There are a few factors that we take into consideration when looking at a slot game. These essentially make or break a game in our online slot reviews. So, to find out if your favorite slot should get the title of “best”, we look for the following in a title:

Gameplay and Features

Then we look at the variety of slot gameplay and features being offered. Not only should the gameplay be dynamic and enjoyable, but we also ask if they are offering you anything new. Does it have exciting bonus features? Are they easy to trigger?

And, what do they add to the game? We also look at the scatter symbols, wild symbols (which help with making winning combos), bonus games and multipliers. Furthermore, we look at the number of paylines, the coin size, and the coin denomination of the game.

Top-Notch Graphics

When doing our online slot machines for money reviews, we firstly look at the quality of the graphics. Are they aesthetically pleasing? Do they make the game interesting and exciting? Because there has been a lot of innovation in this area, we expect games to have high-quality graphics.

Type of Online Slot Machine

In this criterion we look at what type of slot machine it is. Is it a three-reel, five-reel, or even seven-reel slot? How many paylines does it come with? This determines how much you’ll be using each round because the more paylines, the higher it costs.
Also, another factor we consider is whether or not the paylines are adjustable (can control how many lines you can play) or fixed (can’t change how many lines spin).

Mobile Slots App Version

People are playing gambling games like online slots more on mobile than ever before. This makes it an important aspect to consider when reviewing a game. If a slot is compatible with mobile devices, it shows that the developers are keeping up with the changes.

Best Online Slot Payout Percentage

Ultimately, slot players go for games with the biggest jackpots and payouts. It’s especially important if you’re playing real money slots. USA players can expect to find two types of jackpots – a progressive jackpot and a fixed jackpot. The first one increased with each person playing the specific game or the games on its network.
Furthermore, there’s the machine’s payout which is measured using the return to player (RTP) rate. This tells you the percentage of money the casino takes and the amount you get in return for every bet. Generally, the average RTP rate is 95%. So, a game that has something higher means it payout more often.

The Software Developer

Finally, we also mentioned that the software provider creates the gamse we play. This is because, with specific companies, we’ve come to expect certain things. For instance, Realtime Gaming (RTG) uses 3D graphics in their games. Others, like BetSoft, are known for having progressive slots that payout big.
