6. Wagerweb.ag
It becomes a general theme on this list, but this is yet another site with too much clutter going on on the homepage and every consecutive page after that.
Again, this doesn’t work on mobile, people’s screens are just too small to be able to handle it.
But there’s more, the plugins that run the main functionality don’t work on mobile. So even if someone manages to go through the difficult to navigate design, they will still not be able to play any game.
