Chapters are a way of quickly traveling on the game map, and they show at a glance the progress you’ve made for each chapter. You can access the chapters in the main menu on the left side of the game screen.

Each chapter represents a section of levels, and for example, in Chapter 1, you can find levels from 1 to 15, levels from 16 to 30 in Chapter 2, and so on. You can tap on a chapter icon, and this action will automatically move you to that selection of levels on the map.

In the Chapters menu, you can also see the achievements available for each chapter, along with the progress toward completing them. Once an achievement is completed, you can collect the reward in the Chapters menu. Complete all the achievements in a chapter, which will be marked as completed as well.
