The structure of the board looks nearly like the teapot.
Prior to its web release, the conveyor belt moves in a circular motion, and candies spawn once the three-layered icing is broken. This makes this level impossible without the use of the free switch. This version is available in mobile v1.64, as the first mobile release usually represent pre-release web versions, and that upon release there are minor revisions.
This is only the third ever level to have the undefined difficulty that may be played. The others are 578, 634 (redesigns prevent this from ever becoming impossible. Also, mobile never had the impossible version), and 380/Dreamworld.
