The Journey is broken into Regionz, which are made up of Citiez, which are made up of Stopz. Each Stop containz one or multiple Gamez that you need to pass in order to move to the next stop.
The first Region in the Journey is Dunitea, and the first City is Ignimbriton. Ignimbriton has 8 Stopz (labeled 1-1-1 through 1-1-8). Each Game also has a name - the first Game in the Journey is called Adalena.
As you complete gamez in the journey, you earn Pebblez Cash (Pz ... i.e., pointz in the game). Your goal is earn the most Pz possible and complete the journey. You can re-play gamez as many timez as you'd like to earn more Pz.
As you complete more gamez, earn more Pebblez Cash (Pz), and complete more stopz, you will earn a higher rank.
