Here's an example of a simple billiards game implemented as a single HTML file, using JavaScript and pictograms for smartphone operation:

This implementation sets up a canvas element to draw the billiards ball. It uses the mousedown event to detect user touch on the canvas and calculates the difference between touch position and ball position to control the ball's movement. The game loop updates the ball position continuously using the setInterval method.

    var dy = -2;

// Draw the ball on the canvas

// Update the ball position and handle collisions

    }

// Handle user touch events for controlling the ball with finger swipe
    canvas.addEventListener("touchstart", function(event) {
      var touch = event.touches[0];
      var touchX = touch.clientX - canvas.getBoundingClientRect().left;
      var touchY = touch.clientY - canvas.getBoundingClientRect().top;
      
      // Calculate the difference between touch position and ball position

// Set the new ball speed based on touch direction

      dy = diffY / 10;
    });

// Start the game loop
    setInterval(update, 10);
