If you'd like to know which blocks are associated with which tasks, you can use the Plan Overview feature in To-Do Adventure. This feature allows you to see each block in your land and the tasks you have completed to discover them. Tap anywhere on the main page to view your plan overview. You'll then see a blueprint of hexagons for each of the tasks in your current plan. You can also tap the timeline on the main page and scroll along the timeline to see each day within your plan.
Note: If any incomplete tasks from yesterday have been delayed to today, you'll see a connecting line to indicate these tasks are a continuation of a previous day's task.
