Concrete mixers at the roadblock
Like in other King Games there is a path leading from level to level. This path is called road. You will move forward each time you succeed on a level. The avatars of your friends show up along the road at the levels they achieved
Episodes are separated by a roadblock. Upcoming episodes are all shown in the mobile version only. If you play with a web interface the road ahead will be covered by fog (of war). Passing the block will remove the fog.
