From the game rules --
For an easier game for younger players:
Use only 6 octagonal tiles in the center, and the 12 matching oval tiles for the path. This is a good, quick two-player game.
For a more challenging and longer game:
Players can choose to collect only one item at a time when they fly over another dragon who is carrying more than one item. This way they will have to fly over their opponent again to collect another item.
