1. Once the game is installed, open it and choose the game mode you want to play. There are usually different modes available such as classic, time trial, or adventure mode.

2. In classic mode, you control Pac-Man, a yellow circular character with a mouth that eats dots and fruit while avoiding four ghosts. Your goal is to clear the maze of all the dots and fruit while avoiding the ghosts. If you touch a ghost, you lose a life. If you lose all your lives, the game is over.

3. To control Pac-Man, swipe in the direction you want him to go. If you want him to turn a corner, swipe in the direction you want him to turn just before he reaches the corner.

4. You can also collect power pellets, which turn the ghosts blue and allow you to eat them for extra points. However, the power pellets only last for a limited time, so make sure you make the most of them.

5. Collecting fruit gives you extra points, but they appear only for a limited time.

6. Once you've cleared all the dots and fruit from the maze, you can move on to the next level. Each level is more difficult than the last, with faster-moving ghosts and more complicated mazes.
