Re: Which Casino and Sportsbook have the best UI? Which others can improve?
For me, Stake has the best UI. The worst ones are Nitrobetting and Coinroyale.
I may not agree that Stake has the best UI but I thing i agree about what you said in Nitrobetting 
anyway I am not enjoying the UI of Duelbits , it may not the best for everyone but at least for me they are qualified as best one maybe because I want simplicity and i find that in duelbits .
I believe this is a typo error you made, so I am quoting you to bring your attention to it and possibly correct it.
Anyways, I won't argue about Duelbits Ui, they definitely qualify to be one of the best, but having played on Duelbits and also on Stake, I won't discredit Stake either, I still like the Stake Ui very much, I don't know about you or any other person but I personally think Stake's UI is very good, things are very easy to understand, navigating around the casino is also a breeze and no complicated or hard to understand features, the site is over all user-friendly, so, if we were to rate, I still give it a 9.5 out of ten, it's not 10 out of 10 because black is not my best color.
