Man, there's still a lot to do, even if you initially made it with desktops in mind, the layout still doesn't adjust well, on my monitor the logo practically doesn't appear, or is that how it is?

I would assume most gamblers use their laptop anyways.
In this regard, you are mistaken. I believe that most gamblers use smartphones to bet. After all, they are with them all the time. A desktop or laptop are certainly more convenient, but many gamble on the way home, in a park, perhaps in a coffee shop...
It's a good idea to start optimizing your website for mobile devices too. You can do this practically at the same time as you develop for desktop devices. Current tools speed up this process.
