How We Select Best Sites?

All Sites Reviews
1 Check the site out for the first time

To properly emulate the user experience and give you a fair assessment, our bingo experts visit the site for the first time to explore the games lobby, check out the promotions and see what kind of first impression it gives.

All Sites Reviews
2 Create an account

To properly gauge what our readers will love about a bingo site, the reviewer will make an account to properly understand the user journey. This is key to giving a complete review, as we can alert bingo fans to any roadblocks or difficulties they might encounter.

All Sites Reviews
3 Claim a welcome bonus and test the games

Once we’ve made an account, we’ll make a first deposit to claim the bonus on offer. Our readers love a good welcome bonus, so It’s important to try each one out to see if it’s as advertised, or if a site is trying to trick you into signing up with big promises.

All Sites Reviews
4 Review the site honestly and assign a fair score

After one of our bingo experts has spent some time using the site and trying out everything it offers, it’s time to write a review that accurately portrays the highs and lows, alerts you to any worries you might have before you’ve made a commitment, and tells you exactly what to expect when you sign up.
