1. First, use the blue pillow in the upper left corner to make a big firecracker, and then use it to clear the Rope in the middle.

2. Second, clear the Books in the lower left corner, especially those four Books at the bottom. They will block the Teleporter and hinder the elimination of the upper right corner. So please be sure to clear all four Books at the bottom.

3. After completing the steps above, start to eliminate the upper right corner. Try to make as many vertical firecrackers or big firecrackers as possible to help.
