Following are all of the rules that determined the scoring of the trading game. The rules are cumulative, so the leg 1 rules also apply to all subsequent legs. The rules are presented here in the approximate order that they would have been discovered.
Most of the rules were embedded in handbook entries that get revealed by clue solutions. These rules were revealed to all teams at the same point in the route, assuming they actually read the handbook. Three of the rules were embedded as puzzles in the Galaxy Today that teams received Saturday morning. Most teams solved these puzzles, although not all.
A handful of teams turned in more than twelve goods at the end of leg 1. One team made what they thought was a sweetheart trade, receiving nine cards for one; they ultimately turned in twenty-six goods. Goods results were distributed shortly after each leg, so few teams made that mistake more than once.
