ESI Ranking System
We’ve created a ranking system to help you quickly know how good each gambling platform is. As gamblers ourselves, we know which factors matter most to you, so we follow a best-in-class methodology to test each one with no stone unturned. Once done, we then rank each platform based on the following tiers:
-
A-Tier High-quality sites that deliver a top experience every time. They boast strong performance, nice features, and reliable support, but are just shy of perfection. -
B-Tier Solid platforms that are worth a spin. They’re safe, fun, and functional, but may be lacking advanced features or have minor drawbacks.
-
S-Tier Reserved for elite operators only. These go well beyond the norm with lucrative bonuses, rewarding promotions, lightning-fast payouts, and a flawless experience overall.
