Arduino Pong game, coding help

Hi, I am a beginer in arduino coding
I want to modify this code to make the game start by pressing a buton( added on pin 7 for example), now the game starts when i am moving one of the potentiometres.
And i want the game to stop to a max score(10), and add 2 leds for each winner. after the leds of the winner turns on for 5 secons lets say, the game will go back to splash screen.
Is that possible? I am to noob to do this… dont’t know where to modify the code.
The main code from Building Pong

my input to your question is to invite you to learn programming

Take a look into this tutorial:

Arduino Programming Course

It is easy to understand and has a good mixture between explaining important concepts and example-codes to get you going. So give it a try and report your opinion about this tutorial.
