Leavenworth Scatter
The following puzzles are all in and around Leavenworth. The general flow is that teams will be sent to a central logistics spot (actual location TBD), and the people at that spot will send them to a puzzle. After solving, they'll get a stamp and be sent back to the logistics spot. After getting all the stamps (or fewer if we need them to move on), they'll be sent to Papers Please.
As such, you might get calls for any of them when teams are in Leavenworth.
