The trip includes a Scavenger Hunt with lots of fun things to collect on the way. Each player has their own copy of the Xiama book to fill up. You can open the book at any time to see how you're going. Many items come from solving puzzles but many puzzles allow partial solutions.
All successes earn a score so there is the possibility of lots of competition between players.
