how to play Carcassonne Labyrinth

About Carcassonne Labyrinth, from BoardGameGeek:

Two popular classic games with a twist - Carcassonne Labyrinth combines the best of both worlds. For 40 years, Labyrinth has been thrilling families worldwide - and for 25 years, Carcassonne has been an international game night favorite. Now, both classics come together in a completely new game. Players push tiles into the layout of the maze to shift the Labyrinth so they may find a path that leads to the treasure they seek. Any treasure tiles they collect and tiles pushed out of the Labyrinth can then be used to build the cities and roads of Carcassonne! The player who moves the most cleverly and builds the most skillfully wins this creative reinterpretation of two timeless games. -description from the publisher
