In addition to the original Ticket to Ride rules, the 30 Wild Wild West event cards are shuffled at the beginning of the game. Three cards are distributed to each player. Each player reviews his event cards and decides which ones to keep. A player must keep at least one card but may keep two or all three.
Playing the event card will cost one action to play an event card.
There are variety of interesting events in this card deck like: "Double the value of any of your completed Destination tickets worth 6 points or less, at game's end" or "This card is revealed at game's end. If you are the first player with 2 or less trains score 10 additional points. Otherwise, lose 5 points. "
