This is a simple implementation of the Pong game using only one HTML file with embedded JavaScript code. The game can be played on smartphones with touch screen controls. The objective of the game is to hit the ball with the paddles and score points by making the ball pass through the opponent’s goal. The player with the highest score at the end of the game wins. The scoreboard is displayed at the center of the screen and updates dynamically as the game progresses. The game also uses emojis to add more fun to the experience.
