Best Slots to Play Online – Slot Reviews and Free Play Slots

In our considered opinion these are some of the best slots to play online. With all the slots reviewed on these pages also available to play for free.

All the free play slots and slot reviews on this page can be found at the online casinos we recommend on our casinos reviews page.

You will find slots from software companies such as Microgaming, Playtech, IGT, Novomatic, WMS ( Scientific Games ), NetEnt and more.

There are currently in excess of 5000 slot machines available to play online. Yes you read that correctly, over 5000 slot machines and counting!

Numbering over 100 of the best slots to play online, our online slots guide features a good selection of the best of the current games available to play, at the casinos online which we feature on OCR. In short in our considered opinion these are some of the best slots around.

The Free Play Slot Machines pages have proven to be a popular section of the site with our visitors. To this extent we plan to grow the number of online slots featured on these pages throughout 2018 and beyond.

In November 2017 OCR featured our first free play slot game from Yggdrasil Gaming with their Golden Fish Tank Slot game. Yggdrasil will be the first of many casino software developers who we plan to add to our free play slots resource.

I sincerely hope you find our slots guide a good resource and more importantly have lots of fun playing the many online slots that we cover.

Should you find that any of the online slots featured on these pages do not work, please let us know, either by posting on our OCR Facebook Page ( Link at top right of every page ) or by sending an email to – slots@onlinecasinoreviewer.com.

Even if you are unable to play for real money many of the slot games featured on these pages, you will be pleased to know the vast majority of our free play slots work perfectly well, regardless which jurisdiction you live in.

Slot Machine Reviews Featuring Over 100 Free Games

All the slot games listed on these pages of our Online Slots Guide have an overall rating provided by us at Online Casino Reviewer. Please note though our individual slot ratings are subjective and slots we may like, you may hate and vice versa.

Unlike with our casino reviews, which are reviewed and rated due to a number of factors, such as payout time, customer service and number of games available. Our slot games are rated based on what the individual slot reviewer on OCR likes about slots. Hence all the slots which have been reviewed, you are also able to try out for free and rate them for yourself.

All the slots featured on these pages are listed in order of the rating bestowed on them by Online Casino Reviewer. We have also listed them by software company ( Drop down menu above ). If you cannot find the game you are looking for, just use the handy search box which is located at the top right of every page of the site.

On these pages you will find some of the best casino slot machine games to play and for free without having to register and open an account at an online casino.

Since the relaunch of Online Casino Reviewer at the beginning of March 2013, our dedicated online slots section has been expanded to include reviews of more games and also many more free play games to try out for yourself.

For information on the best payout slots we reference the Gambipedia site which provides visitors with a list of the top ten best paying slots, currently available to play online.

As of the end of May 2018, new games added, include the superb Planet of the Apes, Microgaming’s Phantom of the Opera and Novomatic’s extremely popular Kingdom of Legend. If you happen to be looking for free play tables games then please visit our casino games resource.

Finally, if you want to keep up to date with the slot games which we feature on OCR and also have a Facebook account, just click the like button in the Facebook Box on the top right hand side of the page.

As well as being informed as to which new games we add to the site, any additional content added to OCR, such as rogue casino warnings, exclusive casino bonus offers and more will be posted to the OCR FaceBook page, as and when they go live.
