Sure, here's an implementation of a simple billiards game that can be played on a smartphone using pictograms. The game allows you to aim and shoot the cue ball to pocket the other balls on the table. The game will end when all balls are pocketed or when you scratch (potting the cue ball), resulting in a foul.
Please note that this is just a basic implementation and may not include advanced features like ball collisions, score keeping, or realistic physics. You can enhance the game by adding these features based on your requirements.
