Where can I find the best online slot games?

There are thousands of slot machines out there for you to indulge yourselves in. The most popular is online video slots, many of which are based on games in land-based casinos. Slots offer a lot of fun, not to mention, rewards, bonuses, free spins, jackpots, progressive jackpots and are often the focus of many casino online promotions and prizes. We love to play our slots, and we will be looking to bring you reviews of the most popular, creative, innovative, lucrative and exciting online casino slots that are available to play today.


As online casinos have developed so has the spectrum of games they offer, and when you visit one today, you can expect to find an all-encompassing experience. The industry has become highly competitive, so, therefore, the choices on offer have grown to be out of this world, with most casinos online offering card games, dice games, virtual table games, and live casino lounges.

You can expect to be able to enjoy a real casino experience from the comfort of your own home, with games like blackjack, roulette, poker, baccarat, and their numerous variations.

With the advent of mobile casino apps and the leaps and bounds in the technology powering our online casino platforms, some of the big guns on the scene have even introduced live sports betting to their larder of treats for you to satiate your gambling appetites.

So you can see why it so crucial for us to give the latest and greatest offerings, as well as making sure you know the games and casinos that provide them are offering you a truly fair and random playing experience.

Terms and conditions

Reading the terms and conditions of the casino online you choose to play at is very important. We will reiterate this time and time again. If you have any issues understanding the T’s and C’s, then a good site will have an in-depth FAQ’s section and customer services that will be able to help. It is imperative that you have a solid understanding of how the casino online you choose to play at will work for you. They should strongly encourage this as much as we do.

Any disputes you may have are unlikely to be resolved in your favour if you just do not understand the rules and as there is no regulatory body overseeing online gaming the online casinos currently have no restrictions over what they include.

At OnlineCasinoMonsters we, unfortunately, cannot break down the T’s & C’s at every casino online we review but we will endeavour to steer you clear from any site we believe is not transparent and forthcoming with the information you need to make informed decisions about where you choose to play!

We get paid if you click

OnlineCasinoMonsters is an affiliate site. Yes, we are a marketing tool for online casinos to use to promote their platforms and yes we do get paid for each customer we bring. There is no bullshit here that is quite simply what we are; affiliate sites are the only sustainable means of implementing some kind of accountability in the industry.

We truly do not give a flying shit if an gambling site does not want to affiliate with our site or pay us for the reviews we write. If we have found them to be a distasteful and, have quite literally massacred them in one way or another.

Quite frankly it is our job, to make sure our readership have the most satisfying experience they can and if you are a casino online who believes in the same well then come and sit at our table will be happy to dine out with you!

We have tried to do our very best to bring you the most accurate and up to date information. We also strongly recommend for your security and benefit that you evaluate any of the online casinos you are interested in playing at yourselves. It is your money and your experience, not ours. Try playing small at first. This is a responsible way to gamble and gives you the time to become comfortable and know you can trust the casinos online you play at!
