I am looking to build a simple BTC game online - basically we would need a website and btc wallet backend system, to be deployed on Linux VPS. We have the website with one btc wallet. Players will be able to deposit as much BTC as they want into the wallet and the balance of this wallet is shown on the website. We also have a countdown timer on the website for 24hrs. Once the timer runs out a winner is randomly selected from all the people who entered the game and all of the BTC that has been deposited over past 24hrs is paid out to the winner, less a fee, which is deposited into our company wallet.
There is some sort of animation or graphic that shows the winner selection on the website. Then the process is repeated.
There is a login/registration feature with social media login
There is a "top winners" or top wins table as well.
