Replicate a program

One time small project for someone who can replicate this program.
http://167.71.148.59/shiny/CoinToss. Instead of showing a coin, we need a number to pop up on the screen. This program is done in R. No need for excellent graphics or advanced visualization. Main requirements:
i. Can log in and change parameters when necessary,
ii. Multiple players can play multiple times
iii. Ability to download data in excel or any other form

Thanks!
