The Manor's rooms are unlocked one after the other as the player progresses. There is no way to skip a room, or change the order of the rooms unlocked. It takes several episodes to completely renovate a room, depending on the player's match-3 performance. As you beat the match-3 levels and earn stars, use those stars on the tasks. Tasks might ask for several stars to complete. After each task for the room is completed, you can start the next room. You can keep track of your task progress from the task popup placed on the bottom left side of the screen.
