CS:GO virtual items jackpot

i want to create a website that is linked to a video game called Counter Strike Global Offensive. The focus of the website will be a jackpot sort of thing where you deposit a weapon camo from the game which costs money into a pool and a randomiser will select the winner randomly to receive all of the skins. The more value you put it the higher your odds. An example that my friend had created and is currently using is this website [login to view URL] I want to make it more visually appealing with maybe a wheel with a pointer that spins and will land on the winner showing the users live who is going to win. another example is [login to view URL] and [login to view URL] let me know if this is possible i know it shouldnt take much.
