The Best Online Casinos in 2021 to Play at (UK Friendly)!

Choosing the Best Online Casinos Made Easy!

At Wild Reels, we have personally played at and tested with real money every online casino that we list on our website. That’s our guarantee and personal promise as a passionate slots player before we even think to write a review or add an article for any online casino that we list on our website.

No bullshit ratings for casinos or fake rated online slot reviews, and no neverending lists of pointless casino “reviews” that always score very highly!

We do, however, list plenty of UK friendly online casinos to play at, but also understand that if you are a brand new casino player trying to make the best choices or are simply searching for a new online casino to try out that having a big list of casinos to choose from can be a very daunting task.

To make your life easier, we have carefully filtered through our current list of recommended online casinos and selected our personal 6 Best Online Casinos for 2021.

How Do We Choose Our Best Recommended Casinos?

On top of our personal recommendations from playing at each of these casinos, we have also taken into account, the generosity of the welcome bonuses and wagering requirements, the frequency and real value of casino promotions and importantly how well existing players are looked after at each casino, with things such as free spins and reload bonuses, and regular extra worthwhile casino promotions not just 10 free spins at min bet size!

Other important factors include – fast payouts, great customer support, a fully mobile-friendly casino, worthwhile and unique features that make these particular casinos stand out from the competition, and of course over the last few years a basic requirement that all newly added casinos must have a valid UKGC Gambling License so we can actually play there!

This is just a handful of the factors we have considered along with real player feedback so you can rest assured that any of the casinos listed here will provide you with a top-notch online casino you can trust and play safely at for years to come.

Whilst a lot of players will be continually searching for new bonuses at less reputable casinos, start with these 6 as a benchmark for how an online casino should operate!
