There is no one specific way to get more apples in  Google Snake Games. However, there are a few things you can do to increase your chances of getting them. First, try to eat as many fruits as possible. Not only will this give you points, but it will also make the snake longer. That can be helpful (or dangerous!) later on in the game.
Another thing you can do is to practice your skills and learn the different patterns of the fruits. The more you play, the better you'll get at predicting where they will appear. With enough practice, you'll be able to snag those apples in no time!
