Pocketdice = 1.9%
So chance of winning in bitsler is higher than in pocketdice. However i like the user interface pocketdice have compared to what bitsler have.
Means that you prefer to play on higher house edge because you like the user interface? How if there is other site with greater user interface than pocketdice but has higher house edge? Lets say 5% or more, will you choose a site to play because the user interface only?
Having good interface design only attract more visitor to your website, people will think twice to play on higher place HE because no one know how much their luck. Also people will think about the website reputation it's fair or not. Since fair was the primary that gamblers needed some people would to played on both site.
